The End of Time (TV story)

The End of Time was a two-part Doctor Who special that was broadcast during the 2009–2010 Christmas season, concluding the "2009 interim season". It featured the final regular appearance of David Tennant as the Tenth Doctor and briefly introduced Matt Smith as the Eleventh Doctor. The story is also noteable for having revealed many aspects of the Last Great Time War, and giving important development to the character of the Master.

From a production standpoint, it marked a significant scene change in the history of Doctor Who. Like only The War Games before it, The End of Time ushered in a complete change of regular cast. Unlike that 1960s story, however, it was also the final story for its principal producers, Russell T Davies and Julie Gardner, and was the last regular story for its head writer, Davies. It was also the first to include any part overseen by — if not credited to — incoming lead writer and executive producer, Steven Moffat. Though Tracie Simpson was the credited line producer, her elevation to regular line producer on the first Matt Smith series meant that Julie Gardner effectively became the line producer for the first and only time in her tenure on Doctor Who.

Part one
It is the Tenth Doctor's final journey - but his psychotic nemesis the Master has been resurrected, on Christmas Eve! With both determined to cheat death, the battle ranges from the abandoned wastelands of London to the mysterious Immortality Gate, whilst the alien Ood warn of an even greater danger approaching, as a terrible shadow falls across the entire Universe...

Part two
The Doctor faces the end of his life as the Master's plans hurtle out of control. With the sound of the drums in the Master's head growing louder, and an ancient trap closing around the Earth, the Doctor and Wilf must fight alone. But sacrifices must be made, and the deadly prophecy warns: "He will knock four times."

Part one
An unseen voice (The Narrator) narrates the opening of the episode, stating "It is said that in the final days of planet Earth, everyone had bad dreams." On Earth, Wilfred Mott, experiencing a vision of the Master laughing maniacally, enters a church. Once inside, his attention is drawn to a stained-glass window bearing the image of the TARDIS. A mysterious woman appears, telling him that the church used to be a monastery in the 13th century, and was attacked by a demon from the stars which itself was repelled by a "sainted physician", whom Wilf recognizes as the Doctor. When the Woman suggests that the "physician" is returning, Wilf states that it would make his Christmas, but turns around to find that the woman has vanished. Heb however, once again sees a vision of the Master laughing, startling him. Elsewhere, in the 43rd century, the Doctor arrives on the Ood Sphere (after some procrastination, having seen galactic wonders, saved another planet, named a galaxy Allison and got married to Queen Elizabeth I, out of fear of his approaching demise). He is greeting by Ood Sigma, who he tries to make laugh by locking his TARDIS like an earth car, including a beep. The Doctor wonders how old Sigma is now, but is soon distracted by the marvelous city that the Ood have built and asks how long it has taken them to build such a society. When Sigma answers that it took only 100 years. the Doctor begins to worry as it is too fast for them to have the technology they have now as Sigma reached out into the 2050's to call the Doctor. Ood Σ|Sigma takes the Doctor to the Ood Elders who show him visions of the Master returning. He considers it impossible, as he saw his wife Lucy shoot him and he personally burned the body. However, the Ood show him something he didn't see: an old woman taking the Master's ring, carrying the essence of the Master. The Ood then warn the Doctor of an even greater danger is returning from the darkness, and that its return precedes 'the End of Time itself'. Among other visions are a scared Wilfred and a "King in his Counting House". The Doctor rushes to Earth in the TARDIS to try and find him. The scene shifts to Lucy Saxon, who has been incarcerated in Broadfell Prison ever since she murdered her husband. One of the warders of Broadfell is Miss Trefusis, the woman who retrieved the Master's ring. On the night of Christmas Eve, the prison governor brings Lucy to a chamber where it is revealed that most of the staff are fanatical disciples of the Master who have been working ever since his apparent death to bring about his resurrection. The governor even comments that unlike Lucy, they never lost faith. With the help of the ring, a biometric imprint taken from Lucy and the sacrifice of the cultists' life force, the Master is reborn in a swirl of energy, but Lucy and some other warders have prepared for this eventuality and Lucy hurls a harmful potion at the Master. This causes an explosion. The Doctor arrives the following day, too late as the prison had obliterated by the resulting explosion. However, the Master had survived the explosion in an immaterial form and later gained form. As a side effect of Lucy's potion, the Master gained supernatural speed, agility and the ability to generate and use electrical bolts as weapons, but his life force is left in a state of constant depletion. This leaves him with constant hunger, forcing him to drain the vitality of a number of homeless people on a desolate construction site as well as eating any food he can find. Wilf, still experiencing faded dreams of the Master, scours London with other pensioners, under the group name the "Silver Cloak", to track down the Doctor. Meanwhile, the Doctor tracks the Master to a junkyard. While still out of sight, the Master taunts the Doctor by beating a trashcan sixteen (four sets of four) times with a pipe, then leads the Doctor on a chase through the junkyard. Despite the Doctor's pleas to let the Master be helped, the Master takes off. However, as the Doctor runs after him, he is interrupted by Wilf and the rest of the Silver Cloak. After retreating to a cafe with Wilf, the Doctor reveals that a prophecy has been made predicting his death. They then notice Donna Noble standing outside, arguing with a police officer over her ticketed car. Wilf explains that she's now engaged to Shaun Temple. He then pleads with the Doctor to at least go up to her and say hello and try to undo what happened to her. The Doctor reminds him that if Donna remembers him for even a second, she will die. The Narrator, his face revealed from out of darkness, talks over the passing of Christmas Eve into Christmas Day, saying that the players are moving into their final positions.

Later encountering the Master, the Doctor discovers that the drumming in his head is not a symptom of insanity, but perfectly real. A squad of troops suddenly appear, sedating and kidnapping the Master and taking him to the mansion of billionaire Joshua Naismith. Back at Wilfred's house, Donna's new fiancé, Shaun Temple arrives and as Wilf tries to watch the Queen's Christmas speech, The Woman appears and interrupts the broadcast telling him to take arms; she also advises him not to tell the Doctor of what's happened, if it is to save his life. Wilf takes his old service revolver out from under his bed as the Doctor contacts him by throwing a stone at his window. Wilf shows the Doctor a book about Naismith, and the Doctor realises that the reason why Donna bought the book as a present was because a subconscious part of her half Time Lord persona is reaching out, and they immediately set a course for Naismith's estate, despite Sylvia's protests. While in transit in the TARDIS, Wilf asks the Doctor why he can't go back to yesterday and catch the Master; the Doctor explains that he can't go back in his own timeline.

At the mansion, Naismith and his daughter, Abigail, are in possession of the "Immortality Gate", which has restorative powers enabling the healing of injuries and, as Naismith hopes, the resurrection of the dead. He acquired the Gate after the fall of Torchwood. Wanting to secure immortality for Abigail, Naismith enlists the assistance of the Master to mend the malfunctioning Gate.

Meanwhile, the Doctor and Wilf arrive at the Naismith estate. The former hides the TARDIS one second out of sync, so the Master can't get to it, who has sensed their arrival. They make their way into the basement, they then discover that two of Naismith's staff, Addams and Rossiter are undercover Vinvocci, members of the race similar to Zocci, disguised as humans with shimmers that the Doctor can see through and deactivate with his sonic screwdriver. She and her partner are pressured into explaining the Immortality Gate is a medical device that heals lifeforms across entire planets using a genetic template. The Doctor realises at this point that the Master is going to use the Gate to do something to the Earth's entire population, but is too late to stop the Master from escaping his captors and jumping into the gate. Almost instantaneously every single human on Earth sees the Master in their minds - the Master had modified the Gate to accomplish much more than simply controlling the humans. He transmits his own genetic template across the entire planet, transforming every single human on Earth into a clone of himself - Wilf is protected from the effect by a radiation shield the Doctor placed him in. Donna is immune due to her half-Time Lord physiology, but as Donna witnesses her mother and her fiancé turn into clones of the Master she starts to remember everything that was erased from her memory. As the Master steps out of the gateway he tells the Doctor that the Human race was always the Doctor's favorite, but it now exists no more, habing been replaced with "The Master Race".

The Narrator claims the Master and his removal of Humanity is only a small part of an approaching conflict. The Narrator is revealed as the Time Lord President of Gallifrey, addressing the Gallifrey Panopticon, which is packed with fellow Time Lords and Time Ladies. The President announces that "This is the day the Time Lords returned. For Gallifrey! For victory! For the end of time itself!"

Part two
The next episode begins on a devastated Gallifrey, on the last day of the Time War. The Time Lord Council has foreseen that the Doctor, in possession of something called "The Moment ", will end the war by destroying both the Daleks and Gallifrey. One of the council says that at the heart of the Time War, billions are dying, being resurrected and dying repeatedly, commenting that the never-ending carnage is a travesty of life and asks that he ends the war once and for all. The Time Lord President kills her with his gauntlet and declared that he will not allow himself or his race to die. To try and prevent this, the Time Lord Council concocts a plan which involves retrospectively implanting a link to the Master during his early childhood (the four-beat drum rhythm that has tormented the Master all his life), followed by sending a Gallifreyan "Whitepoint Star" diamond to Earth as a further, more physical, link. This link to the Master's present location will then enable the Time Lords to escape from the Time War's Time Lock, and so escape their impending destruction at the hands of the Doctor.

On Earth, the Master has both the Doctor and Wilfred bound, gloating over his victory. As of now, the Master Race has control of all military armaments. Then suddenly, Wilfred's mobile phone starts ringing. Knowing that he would never call Wilfred, given that everyone on Earth are now copies of himself, the Master searches through Wilfred's coat, before finding the phone, which is receiving a call from Donna. The Master turns it on and hears Donna's voice, who is confused over her family and everyone else changing. Suspicious, the Master demands to know why Donna didn't change. Wilfred reluctantly admits about the metacrisis that made her part Time Lord. Spurred on this information, the Master taunts the Doctor on this, sneering "He does love playing with Earth girls!", then orders his copies to take her down. He gives Wilfred the phone to say his last good-byes, snidely saying "Say goodbye to the freak, granddad!". Instead, Wilfred urges Donna to run. Unfortunately, she is cornered by the Master Race. Even worse, she is starting to remember her adventures with the Doctor and the various creatures they encountered. Instead of burning up, she emits a heat pulse that knocks everyone unconscious, including herself. Upon hearing nothing and seeing the Doctor smile, the Master removes his mouth gag. The Doctor then admits that he left Donna, his best friend, with a defense mechanism in case this happens.

The Master then asks him about the whereabouts of the TARDIS. The Doctor dodges the questions, remarking that the Master could have so much more potential and urges him to see and hear the universe simply for the pleasure of appreciating it, not the rabid desire to destroy and conquer. However, the Master then realizes that the four-drum beat sound is from across time itself. He demands to know where the TARDIS is, threatening to kill Wilfred. However, the Doctor casually notes "you know the most amazing thing about you is that after all this time, you're still bone dead stupid." The Master doesn't take well to that comment and motions the guard next to him to take aim. The Doctor then points out that even with six billion pairs of eyes serving him, the Master has failed to notice that the guard is one inch too tall. When the Master swings his head, the guard hits him in the head with the rifle. The guard is actually Rossiter, who frets over actually hitting someone, which he had never done in his life. Addams then rushes in and urges her partner to get the two men out of the mansion. However, Rossiter, unable to free the Doctor from the chair he is strapped to, is forced to wheel the chair along, down several flights of stairs, prompting the Doctor to say "worst... rescue... ever!"

Reaching the basement, the group teleport to the orbiting Vinvocci ship, narrowly escaping the Master and his guards. As Wilfred is amazed at the prospect of being in space, the Doctor is more concerned over what the Master will do. As soon as he gets out of his restraints, he destroys the teleporter, preventing the Master Race from following them. He then asks for directions to the bridge, pointing out that the Master has every missile on the planet ready to fire. However, when they arrive, the Vinvocci are only concerned with leaving, so the Doctor resorts to destroying the ship's systems to prevent their detection, leaving them dead in orbit. As he begins repairing the systems, Wilfred sees The Woman again, who instructs him to give his gun to the Doctor.

During this time, Rassiilon's White Point Star has arrived on earth and has been found by the Master. Back on the ship, the Doctor is still repairing the systems. Wilf then talks to him about many things and tries repeatedly to have the Doctor take th gun to save himself by killing the Master. However, the Doctor refuses and Wilf begins to cry from his fruitless efftorts, prompting the Doctor to hug him. A broadcast from the Master reaches the ship; in which he says he found the diamond, and that it can only mean the Time Lords are returning. Wilfred considers this good but the Doctor says that the Time War had changed the Time Lords, making them far more dangerous than any of his enemies. The Doctor has successfully repaired the ship, but is told by Addams that she will not have them going to earth. However the Doctor reponds, "There's an old Earth saying, Captain. A phrase of great power and wisdom and consolation to the soul in times of need." Addams asks what it is and the Doctor responds, "Allons-y!", taking control of the ship and speading towards Earth. Rossitor and Wilf take charge of the astroroid lasers and blast away the missles the Master has launched at them. Addams plots a course for Naismish's mansion and the Doctor jumps out of the ship, crashing through the skylight and into the Immortality Gate room. However, he is too late to stop the Master from establishign the link to bring the Time Lords back. as not only is the Master in the room, but so are the Time Lord Council. The Master then brags that he plans to implant himself in every Time Lord, but the President uses his gauntlet to reverse the transformations, thus restoring humanity to normal. The President tells the humans present to kneel as "the ascent" begins. The Master is confused as to what could be ascending as the Doctor angerily tells him that not only the Time Lords are coming back, but so is the planet. Gallifrey begins to materialise near Earth, fulfilling the prophecy that "it" (a previously unspecified entity) is returning. At the same time, Wilf has returned to help the Doctor, but frees a trapped man in the control booth, trapping himself. At first, the Master believes it excellent that the Time Lords are restored to the universe, but the Doctor says with the Time Lock broken, all the other horrors created in the Time War and sealed in the Time Lock as well – the reason for the destruction – have been released as well; not only the Daleks, but the Skaro Degradations, the Horde of Travesties, the Nightmare Child, the Could've Been King with his Army of Meanwhiles and Neverweres; the war turned into hell, which is exactly what the Master has unleashed above Earth:in short, "Hell is descending". The Master delights at the thought of such chaos but the Doctor states that even the Time Lords can't survive such an onslaught.

The Time Lord President reveals they had planned this moment since the Time War, that all creation and all of time will be destroyed and the Time Lords will ascend to a higher form of existence and become pure consciousness. The paradox created would eventually rip the Time Vortex apart. The Master begins to realise that the Time Lords had planned to use his life as a means for them to escape their inevitable death, at the cost of creation itself. He asks to join them, but the President disgustedly retorts "You are diseased, albeit a disease of our own making. No more". The President is about to kill the Master when the Doctor pulls out Wilf's gun. The Doctor initially aims at the President, and the Master goads him on, telling the Doctor to kill the President and claim Gallifrey for himself. At this, the Doctor spins and aims at the Master. Initially astounded, the Master realises the reason; the link that brought the Time Lords to Earth is inside his head, and if he dies, the link is broken, returning them back to the Time Lock. However, the Master points out that killing the President would have the same effect. As the Doctor frets on what to do, the President sneers "The final act of your life is murder. But which one of us?"

After agonizing over who to shoot – the Master, or the Lord President (revealed moments later as Rassilon, founder of Time Lord society), the Doctor makes eye contact with one of the "disgraced" Time Lords kneeling behind the Lord President. She is the woman that Wilfred had seen previously, and her eyes indicate the diamond which is anchoring the Time Lords outside the time lock. The Doctor aims at the Master once again, but says "Get out of the way." The Master, realising that he intends to shoot the diamond, complies and the Doctor shoots it. "The link is broken. Back into the Time War, Rassilon. Back into hell!" Gallifrey vanishes back into the Time Lock; Rassilon is furious, and refusing to die alone, attempts to kill the Doctor. But the Master saves the Doctor by ordering him to get out of the way and attacking Rassilon with his electric powers, four times to represent the drumming and the time lord's creation of his insanity. This blasts the Lord President back into the Time War. There is a bright flash of light, and the Time Lords, the Master, the Lord President, and (somewhat slower) Gallifrey, are gone. The Doctor struggles to his feet, not quite able to believe he has survived. Then in the moment where he smiles happliy that he finally feels safe, his face changes to shock, and he is horrified to hear four hesitant knocks, the sound that portends his death. Wilfred is trapped in a radiation containment device and wants to be let out and can only be released at the cost of the Doctor's own life: fulfilling the prophecy that "he" will knock four times and the Doctor will die. After emotionally bemoaning that he must sacrifice his own life for Wilf's, he concludes he may have lived too long, releases Wilfred, and enters the containment device, receiving a massive level of radiation poisoning.

Although he survives initially, the effects on his body show that his regeneration has started, such as the cuts he received from crashing through the skylight. Unlike some previous occasions, he doesn't regenerate immediately. He takes Wilfred home and promises to see him one last time. When Wilfred asks where he's going, the dying Doctor says he's going to get his reward...

The Doctor travels to several times/places: saving Martha and Mickey (who are now married) from a Sontaran, saving Luke Smith from being hit by a car (and exchanging a meaningful look with Sarah Jane), and going to an alien bar to connect Captain Jack with Alonso Frame while the song "My Angel Put The Devil In Me" plays from the Daleks in Manhattan. Afterwards, he visits a book signing of A Journal of Impossible Things by Verity Newman, Joan Redfern's great-granddaughter. He then pays a secretive visit to Donna Noble's wedding, where he gives Wilf and Sylvia the gift of a (presumably winning) lottery ticket to pass on to Donna. He purchased this by travelling back in time and borrowing "a quid" off Donna's late father, Geoff Noble. He also (off screen) visits his past incarnations companions to see how they got along after their travels with him.

Finally, the Doctor goes back to the Powell Estate on New Year's Day 2005, the year that he first met Rose Tyler. Hidden partially from sight in the shadows, he informs the young Rose that she will have a great year. As she leaves smiling, the pain of regeneration sets in. The Doctor attempts to get back to the TARDIS, but he collpaes in the street.

Ood Sigma appears to him to tell him that the entire Universe will sing for him, signing him to "his sleep". The Doctor picks himself up and continues towars the TARDIS as Sigma cotinues "This song is ending, but the story never ends." The Doctor enters the TARDIS, typically tossing his coat on one of the coral structures and notices regeneration enegry is coming out of his hand. He sets the TARDIS off on course for space as he cricles the console. On the brink of tears, the Doctor sadly states: "I don't want to go." Golden energy begins emmiting fully from his hand and head as he breathes heavily and prepares to lose his current incarnation. He stretches his arms and begins to regenerate into the Eleventh Doctor. However, this time the regeneration occurs in an unusually violent manner. The energy dispensed by his hands shatter the TARDIS windows and set the console room ablaze, destroying one of the collums and causing debris to fall from the ceiling. The new Doctor quickly examines himself to make sure his body parts are still in the same place, not noticing the damage his TARDIS sustained until another explosion catches his attention. However, once he does notice, he is rather happy with the chaos going on inside as the TARDIS begin plumeting towards Earth. Whooping happily, the Doctor grabs the console and happily shouts,"GERONIMO!!!!"

The Doctor

 * In the first part, the Tenth Doctor lists off things he did instead of rushing to meet Ood Sigma; among them is an implied marriage with Elizabeth I. He also implies that one nickname for her can't be used anymore. The Doctor had previously encountered her in DW: The Shakespeare Code, at which point she treated him as an enemy. Liz 10 later said that the nickname he sullied was "the Virgin Queen."
 * When the Doctor talks to Wilf in the Cafe, he mentions he did terrible things while travelling alone, possibly referencing the events of DW: The Waters of Mars.
 * This is not the first time that the Doctor has bought a lottery ticket for someone. He did so before in DW: School Reunion, using it in order to have a teacher leave so he could replace her.
 * The Doctor considers the amount of coincidence around Wilf, and the sheer unlikelihood of the two meeting so many times. He also mentioned this about Donna in DW: Turn Left and DW: Journey's End.
 * Wilf tells his fellow seniors that the Doctor usually wears a brown suit and sometimes a blue suit.

Individuals

 * Netty, a character from NSA: Beautiful Chaos, is referred to as a member of the Silver Cloak.
 * "Jimbo", previously mentioned by Matron Cofelia in DW: Partners in Crime, was mentioned in this episode by Jackie Tyler whilst the Doctor travelled back to 1st January 2005, to say his farewells.
 * Joshua Naismith has a book titled Fighting the Future, which could be a reference to the many alien invasions in the past few Earth years or the movie spawned by popular sci-fi series The X-Files.
 * The name of Jessica Hynes' character, Verity Newman, is a reference to Verity Lambert and Sydney Newman. This is the second time the revived series has honoured the two people who are considered among the primary creators of Doctor Who; a similar reference occurred in DW: Human Nature when the Doctor, under his human guise, says his parents were named Verity and Sydney. In this episode, Hynes plays a descendant of Joan Redfern, a character featured in Human Nature.
 * Wilf mentions the planets in the sky. (DW: The Stolen Earth/Journey's End)
 * A woman on the minibus named 'Sparrow Lane' was called Sally. This could be a reference to Sally Sparrow. (DW: Blink)

Time Lords and the Time War

 * The Doctor reveals the Narrator to be Rassilon.
 * The Woman's identity is not revealed, leaving speculation as to who she is.
 * Also left unrevealed is the identity of the second disgraced Time Lord, who could be either male or female. Behind the scenes photos show the second actor to be male.
 * The Nightmare Child is mentioned to be one of the "horrors of the Time War."
 * In the second part several crashed Dalek Saucers are seen next to a badly damaged Citadel. This is shown to be the Last Day of the Time War, before the Doctor destroys Gallifrey.

Races and Species

 * The Vinvocci imply that they are connected to the Zocci, as the Doctor refers to having met one. (DW: Voyage of the Damned)
 * A Sontaran briefly appears going after Martha and Mickey, who are married.
 * A Raxacoricofallapatorian, an Adipose, Judoon, Graske, Sycorax, a Uvodni, and 3 Hath all have cameos in a space cantina, along with Jack Harkness and Alonso Frame. Additionally, there are several unnamed new species present.
 * Rassilon states that the Woman and the other Time Lord will "Stand as monument to their shame, like the Weeping Angels of old." This is a reference to the Weeping Angels seen in DW: Blink.
 * The Doctor has saved a planet from the Red Carnivorous Maw.

The Master

 * During his resurrection, the Master tells Lucy "You will obey me!" This was a frequent catch phrase used during his previous incarnations, particularly during the UNIT years.
 * The scene in which the Doctor begs the Master to understand the difference between ruling the Universe and having unfettered freedom to travel through it parallels a similar conversation between the two in DW: Colony in Space.
 * The Master has also caused the Doctor to indirectly regenerate before. (DW: Logopolis)
 * The Doctor refers to the Master as Skeletor, the skull-headed villain from the 1980s cartoon series He-Man and the Masters of the Universe.

Objects

 * Donna Noble putting the Lottery Ticket down the front of her wedding dress is a reference to the running joke in DW: The Runaway Bride about wedding dresses not having pockets.
 * Joshua Naismith's book was published by Garden Tower Books, who published REF: The Torchwood Archives.

Real world

 * In the second part, when rescued by the Vinvocci, the Doctor cries 'worst rescue ever', a cultural reference to 'Comic Book Guy', a character in The Simpsons.
 * Pictures of various historical Earth individuals can be seen in Joshua Naismith's mansion.

Devices

 * Wilf mentions ATMOS. (DW: The Sontaran Stratagem/The Poison Sky)

UNIT

 * In the second part, a UNIT officer (with the Master's appearance) from UNIT HQ in Geneva appears.

Story notes

 * This was David Tennant's final appearance as the Doctor as well as Matt Smith's first appearance in the role.
 * The original title for Part 1 was The Final Days of Planet Earth, and was in fact the title when Davies teased readers of Doctor Who Magazine with the statement that the title was six words long. Later, however, he decided to give the title The End of Time to both specials.
 * The second part is 75 minutes, four minutes longer than DW: Voyage of the Damned. Thus, it is the new holder of the title of third longest single episode, behind the 90 minute long DW: The Five Doctors and the 85 minute long DW: Doctor Who.
 * The person who knocks four times was Wilf.
 * The End of Time marked the last appearance of Elisabeth Sladen as Sarah Jane Smith in Doctor Who. She died on the 19th April 2011.
 * With this, his final Doctor Who story, Davies will have written or co-written no less than ten consecutive episodes (this number counts two-parters as separate and also includes a mini-episode, but does not include Torchwood), an unprecedented accomplishment in the history of the franchise.
 * This is the first story of more than one episode since DW: Survival to have one overarching title.
 * The Time Lords return after their apparent destruction in the Last Great Time War. This is their first appearance onscreen since DW: The Trial of a Time Lord in 1986, except for a flashback in DW: The Sound of Drums.
 * This is a second time that a Sontaran has appeared as a cameo in a regeneration story, the first time being the Fourth Doctor's final story Logopolis
 * This is, along with DW: The Deadly Assassin, Doctor Who, Army of Ghosts, The Family of Blood and Cold Blood, one of the only Doctor Who stories to feature narration. However, in this case it is revealed that the "narration" is in fact part of a speech given by the Lord President to the High Council.
 * There is no traditional celebrity cameo in the story. Instead, a stand-in plays US President Barack Obama and stock audio from a speech of his is dubbed in. This is the first time in the revived series that the real world US presidency has coincided with that featured in the Whoniverse.
 * The opening credits list David Tennant, John Simm and Bernard Cribbins. Simm is the second person to be credited in the opening credits for playing a villain. The first was Eric Roberts, who likewise played the Master, in DW: Doctor Who. This is only the third time that all of the credits were male (the first being DW: Time Crash and the second being DW: The Next Doctor), discounting Attack of the Graske and Music of the Spheres, in which David Tennant is credited alone.
 * Despite this being David Tennant's last regular Doctor Who story, he filmed scenes for SJA:The Wedding of Sarah Jane Smith, after the production of this story.
 * In the Doctor Who Confidential for this episode, and the ones for the other 2009 specials, the TARDIS in the opening titles bears the St. John's Ambulance badge, a nod to the Eleventh Doctor.
 * The continuity announcement before part 2 was voiced by the Tenth Doctor, and was the last time that the Christmas ident featuring him was used.
 * Russell T Davies confirmed in the commentary for part 2 that the scene where Captain Jack is in an alien bar is in a city named Zaggit-Zagoo on the planet Zog. The scene, a tribute to the famous Cantina Bar scene in Star Wars Episode IV: A New Hope, features cameo appearances by many alien species featured during the Davies era, plus the return of Alonso Frame (DW: Voyage of the Damned) and also features the song "My Angel Put the Devil in Me", last heard in DW: Daleks in Manhattan.
 * Russell T Davies has said in an interview that The Tenth Doctor's death had been planned out since David Tennant was signed on for the role. Davies also heavily implied had Tennant not been cast, the Tenth Doctor would have died a different way.
 * During the Doctor Who Confidential episode for part two, Davies stated that the name of the Vinvocci's ship was 'The Hesperus'.
 * The Master redeems himself by sacrificing himself and saving the Doctor. According to historical accounts of the production of the classic series, this idea dates back to the original concept for Jon Pertwee's final story as the Third Doctor, which would have seen Roger Delgado's Master redeem himself in a similar fashion; Delgado's death ended this idea.
 * Given that the canonicity of the interactive of DW: Attack of the Graske and the fourth wall-breaking skit DW: Music of the Spheres are up for debate, the appearance of a Graske in the cantina scene marks the species' first undeniably canonical on-screen appearance in Doctor Who proper following several appearances in the spin-off The Sarah Jane Adventures.
 * Davies originally considered having the Time Lords in an alliance with the Daleks, but after consulting with Steven Moffat and correspondent Benjamin Cook, eliminated this plot thread. (REF: Doctor Who: The Writer's Tale - The Final Chapter).
 * A line where the Doctor said that he was "half human for a couple of days in 1999" was cut.
 * The End of Time was not the only finale considered. In another, the Tenth Doctor was going to bow out in a one-parter, saving a family of four aliens from a radiation leak.
 * In an early draft of the script, Davies had the Doctor address the "half-human" statement the Eighth Doctor made in the 1996 TV movie, dismissing it as "a 48-hour bug". The line was cut by Davies for several stated reasons, including the fact it would have confused viewers who were only familiar with the events of DW: Human Nature. (REF: Doctor Who: The Writer's Tale - The Final Chapter)
 * During the chaotic sequence after the regeneration, the Eleventh Doctor is shown spitting, an act that raised some eyebrows. In addressing this during a publicity event for the launch of Series 5, Smith explained that it was his natural reaction to all the debris raining down on him during the filming, while Steven Moffat indicated that Davies chose to leave it in.
 * Russell T. Davies claimed that Omega was originally going to appear instead of Rassilon, but the idea was dropped.
 * Joshua Naismith mentions that the Gate was found buried at the foot of Mt. Snowdon by Torchwood. In DW: Doomsday, Yvonne Hartman states that the gravity clamps were found buried in the same place. Presumably, this means the gravity clamps are of Vinvocci origin. However, in Death of the Doctor, UNIT has a base at Mt. Snowdon, which could also imply that whoever the clamps belonged to, UNIT buried them.
 * Before the Doctor regenerates and the TARDIS flies away from Earth, the words "God save the TARDIS" and "God save our saviour" can be heard in the choir that sing in the background.
 * This episode is the only time since the Last Great Time War that the Doctor has regenerated alone.
 * Sinead Keenan and Russell Tovey, who both appear in this episode, play a couple in Toby Whithouse's series, Being Human. In this episode, however, they never appear in a scene together.

Rumours

 * It was rumoured that Martha Jones and Mickey Smith would not appear (in particular given Freema Agyeman's commitments to the non-BBC production Law & Order: UK), however this was proved false as the two appeared as did Billie Piper and John Barrowman, whose involvement had been reported in the press during production of the specials.
 * Prior to the BBC's official announcement in mid-November, it was unclear whether Part 1 and Part 2 would both carry the same title (as prior to this only the title of Part 2 had been confirmed by the network). Following the broadcast of DW: The Waters of Mars, Russell T Davies was quoted in the media as saying the title of Part 1 would have six words, leading to speculation over what it might be before it was announced that the two chapters would share the title The End of Time. The original name for the first part was "The Final Days of Planet Earth" but this was changed by Davies as he felt that it didn't fit the episode as a title.
 * It was hinted by Russell T Davies that Donna Noble and/or Wilfred Mott would die, mentioning "Donna's final words" and speaking grimly of Wilf's fate in The End of Time. In another interview, Bernard Cribbins also made a cryptic statement regarding Wilf possibly "regenerating." Ultimately, both characters survived.
 * It was rumoured that Harriet Jones would re-appear, but she did not.
 * It was widely reported in media and on fan discussion boards that the character played by Claire Bloom would be the Doctor's mother. Ultimately, the woman's identity was left a mystery. A variety of speculation emerged. Some people supposed it to be the Doctor's mother, others believed it to be an alternative world's Donna based on the way the Doctor looked at her after Wilf asked who the woman was, or, by the same logic, Susan, who is the Doctor's own granddaughter. IMdb originally reported the character as being the Doctor's former companion, Romana. This was taken down shortly after it was posted. Julie Gardner in the episode commentary, stated that she would like to believe that this woman is the Doctor's mother, however Davies then stated to the podcast listeners "It is whomever you want it to be".
 * Similarly, the identity of the other dissenting Time Lord is also left a mystery. The character is mentioned as male by Russell T Davies, but the costuming and camera angles make it difficult to determine gender.
 * When it was reported that Billie Piper would appear, speculation mounted as to whether the events of Journey's End would be undone, or if somehow she and the Meta-Crisis Tenth Doctor would somehow be able to leave Pete's World. Ultimately, Piper appeared in a context that prevented conflict with Rose's character arc, as Tate's appearance did not undo Donna's arc.
 * Many fans speculate that Rassilon's glove is the Hand of Omega; it uses the same prop as the Resurrection Gauntlet from Torchwood, a glove used by an unknown humanoid alien race that had (possibly among other powers) the ability to bring back the dead.
 * The Tenth Doctor's last words would be "Don't forget me." This stemmed from "A Letter from the Doctor", a feature written by Russell T Davies for Doctor Who Storybook 2010 which consisted of fragments of dialogue and descriptions taken from TV various TV episodes, in reverse chronological order. The first words of the Letter are "Don't forget me", while the last were "Hello! Ooh, new teeth..." which were similar to the first words uttered by the Tenth Doctor in DW: The Parting of the Ways. This led to newsgroup-based speculation that extrapolating from the format that the final words of the Tenth Doctor would be "Don't forget me." Ultimately, the final words of the Tenth Doctor were, instead, "I don't want to go." The Tenth Doctor does, however, say "Don't forget me," to Sarah Jane Smith when they part company in The Wedding of Sarah Jane Smith which was the last episode filmed by David Tennant as the Tenth Doctor (and which echoed Sarah Jane's words to the Fourth Doctor when she initially left the TARDIS in DW: The Hand of Fear). In The Writer's Tale: The Final Chapter, Davies reaffirms a statement made soon after Tennant joined the series that his final words, "I don't want to go", were written long before Tennant's final regular episode was composed.

Production errors

 * Russell T Davies rather expensively changed his mind about the way the Vinvocci were to look. He had originally envisaged they would only be partially green. Because principal photography had already wrapped, the only solution was to digitally composite a more complete green, and this necessitated frame-by-frame colouring of the Vinvocci scenes. (PCOM: The End of Time) At certain points in the narrative, the process fails to work convincingly, likely because of interaction with studio lighting. One obvious instance is when Rossiter is climbing into the mining laser pod while the Vinvocci ship is under fire from the missiles.
 * The security camera footage viewed by Joshua Naismith on his laptop is the same as the footage used in the episode DW: Rose on the news bulletin showing the destruction of the Henrik's Department Store.
 * When the Doctor hides the TARDIS it doesnt fade out completely at the top, you can see it still a little bit on the wooden background of the celing
 * When the Doctor goes to get A Journal of Impossible Things signed, the woman signing it is quite plainly hovering her pen just above the page and not writing in it.
 * When Rose goes into the block of flats after speaking to the Doctor, a "No Smoking" sign can be seen. This scene is set in 2005 and these signs weren't used until the smoking ban in England was introduced in 2007.
 * When the Doctor arrives at Donna's wedding, the gates he stands behind are closed, but when Wilf and Sylvia approach him, one is open. Also, when Sylvia looks at him, the TARDIS is closer to the Doctor than when they approach him.
 * The Nuclear Bolt control room switches sides of the Naismith's main hall at various points in part 2: It starts off on the right side in part 1, and stays that way until the Master reveals his true intentions to rescuing the Time Lords to Rassilon. The next shot (when all the Masters look smugly at Rassilon) shows the Bolt on the left hand side. It later swaps back to its original position. This seems to suggest the post-production crew 'flipped' the shot, which was unnecessary.
 * Similarly, the occupants changed sides within the Bolt room. Two Masters (Yellow shirt and purple shirt) did a change-around, with the purple-shirted Master taking the place of the yellow-shirted one. The first time this happens, the purple-shirted Master is on the left-hand side, and the yellow-shirted Master on the right. In the aforementioned shot (of the Masters looking smugly at Rassilon; when the Bolt swaps sides the first time), the purple-shirted Master is now on the right-hand side of the Bolt (which would be explained by a reflection of the shot). When the Bolt swaps back to it's original side, the purple-shirted occupant is once again on the right-hand side (which would not be explained by a reflection of the shot), rather than the left-hand side (Which Wilf then occupies).
 * When the Doctor is aiming Wilf's gun at the Master and Rassilon, the trigger of the gun has already been pulled in and it should've fired.
 * During the regeneration scene, the Tenth Doctor stands on the door side of the console, but when the Eleventh Doctor turns around, the handbrake lever can be seen, which is at the other side of the console.
 * After the Doctor knocks Jask out, the latter's body disappears.
 * American newsreader Trinity Wells pronounces "Barack" in the British manner, a pronunciation not in general use in the United States.

Continuity

 * The fall of Torchwood is mentioned. (DW: Army of Ghosts/Doomsday, TW: Children of Earth)
 * The Master returns, and there are flashbacks to the events of DW: The Sound of Drums and Last of the Time Lords.
 * The Immortality Gate was previously referenced in SJA: The Wedding of Sarah Jane Smith, as "the Gate" which The Trickster indicated was waiting for the Doctor.
 * When Donna remembers the Doctor several things from her time with him appear, included are Empress of the Racnoss (DW: The Runaway Bride), the Adipose (DW: Partners in Crime), Ood (DW: Planet of the Ood), the Suit Creature (DW: Silence in the Library/Forest of the Dead), the Vespiform (DW: The Unicorn and the Wasp), Sontarans (DW: The Sontaran Stratagem/The Poison Sky), a Pyrovile (DW: The Fires of Pompeii), Dalek Caan, Davros and the Supreme Dalek (DW: The Stolen Earth/Journey's End). The Judoon (DW: The Stolen Earth) can also be heard in her memories.
 * Alonso Frame (DW: Voyage of the Damned) is sitting next to Jack Harkness, who appears depressed, in an alien bar, and the Doctor hints they should start a relationship, following his loss of Ianto Jones. (TW: Children of Earth)
 * The Doctor mentions Joan Redfern to her great-granddaughter Verity, asking if she was happy after "John Smith" had gone, referencing the events of DW: Human Nature/The Family of Blood.
 * The song My Angel Put the Devil in Me is playing in the alien bar. It was first heard in DW: Daleks in Manhattan.
 * The circumstances of the Tenth Doctor's regeneration echo that of the Ninth Doctor: Absorbing a massive amount of energy into his body, in order to save the life of another. (DW: The Parting of the Ways)
 * The Doctor previously was forced to regenerate due to suffering near-lethal radiation poisoning DW: Planet of the Spiders.
 * Donna's neighbour who appeared throughout Series 4 is finally given a name in part one, Sally.
 * Nerys previously appeared in DW: The Runaway Bride.
 * The notion of Gallifrey being moved due to Time Lord action from the constellation of Kasterborous to Earth's solar system isn't the first time the Time Lords have shown the ability to relocate an entire planet. In DW: The Trial of a Time Lord, the planet Ravalox is revealed to be Earth, relocated to another part of the universe by the Time Lords. And DW: Journey's End revealed that (with a little assist), a single TARDIS is powerful enough to move the Earth.
 * The Doctor knocks out a Sontaran using the exact same method used by Donna in DW: The Poison Sky.
 * The Doctor states that he is 906 years old, implying that three years had past in his personal timeline since DW: Voyage of the Damned. This also suggests that he may have been 903/4 while with Donna and that Planet of the Dead, The Waters of Mars, Dreamland, The Wedding of Sarah Jane Smith and The End of Time took place over the course of two, or three, years for the Doctor.
 * Early on in the bar scene, a creature somewhat resembling a Silurian is present, although it does not have a third eye. It is unlikely that this is actually intended to be a Silurian, due to the physical difference, and as there has been no indication previously of Silurians engaging in inter-stellar travel.
 * When the Doctor is pointing the gun at the Master, the Master states that the Doctor "never would." The Doctor used these words himself in DW: The Doctor's Daughter, when holding Cobb at gunpoint.
 * Also in the bar scene, another white furred alien appears, reminiscent of a character who appeared in the cantina scene in Star Wars: A New Hope, Muftak.
 * This is not the first time the Master has been trapped in a body that is slowly dying. When he stole the body of a human named Bruce, that too began to perish.
 * Numerous previous references have been made to the Doctor destroying his own kind (the Time Lords) as well as the Daleks during the Time War.
 * The Master reminisces about how "we" (presumed to be himself and the Doctor) used to run through fields of red grass on his father's estates, shouting up at the sky. This is the first reference to the Master's family, as well as presumably a reference to the fact the Doctor and the Master were once friends (previously confirmed in other stories). The fact the Master refers to "my father's estates", and not "our father's estates", can be seen as implying that the Doctor and the Master are not brothers.
 * In The Five Doctors, Rassilon has achieved immortality, though in a passive state. Somehow he has been revived and restored to mastery over Time Lord society.
 * The Doctor refers to Donna as his best friend, a title he had previously conferred on Sarah Jane Smith, (DW: The Seeds of Doom) K9 Mark II, (DW: The Pirate Planet) and (presumably in jest) Malcolm Taylor (DW: Planet of the Dead).
 * The Doctor tells Wilf that some people wait centuries to find him. One example of such is Captain Jack Harkness, who waited over 100 years to find him again after being stranded in the late 19th century. (DW: Utopia, TW: Fragments)
 * The Doctor tells Wilf that he has taken lives in the past, and that he &quot;got clever, manipulated people into taking their own."
 * The Doctor looks at his right hand and regeneration energy can be seen. He does the exact same thing in DW: The Parting of the Ways and The Stolen Earth.
 * The revelation that the signal in the Master's head was patterned after the beating of a Time Lord's twin hearts was well hidden, as whenever the Doctor's heartbeat was checked in the new series, it was alway done one at a time, rather then both at once, which would have given it away (DW: The Christmas Invasion/Smith and Jones)
 * The Doctor was previously called a "physician" by the Empress of the Racnoss. (DW: The Runaway Bride)
 * This is the second Christmas Special of the revived series in a row to feature an antagonist which has previously appeared. But, this episode features the introduction of the Master, the Time Lords, Rassilon, and the Sontarans.
 * The Doctor tells Josephine Jones that he visited her prior to his regeneration and that he also visited every companion that he ever had (SJA: Death of the Doctor). This statement is supported in the spin-off media by the fact that he visits companion Heather McCrimmon in the Doctor Who Adventures comic strip DWAM: Lucky Heather.
 * The Master has said "Go on then...Do it!" When a gun was aimed at him before (DW: Last of the Time Lords)

'Ginger' controversy
During the final scene, the Eleventh Doctor takes a look at his hair and utters the phrase, "Still not ginger!" This statement was misinterpreted by a number of viewers as being a negative comment on redheaded people, resulting in more than 140 complaints being filed with the BBC. In response, the BBC issued an official statement clarifying that the Doctor was stating disappointment at not being ginger, a reference to the Tenth Doctor similarly expressing a wish to be ginger in DW: The Christmas Invasion. In response to claims of an "anti-ginger agenda" by the series, the BBC statement noted that the Doctor's two most recent ongoing companions, Donna Noble and Amy Pond, are both redheads.
