The End of Time (TV story)

The End of Time was a two-part Doctor Who special 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 introduced Matt Smith as the Eleventh Doctor. The story is also notable for revealing details of the Last Great Time War, and giving important development to the character of the Master.

From a production standpoint, it marked a sea 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! Each determined to cheat death, the battle rages 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 growing louder in the Master's head and an ancient trap closing around the Earth, the Doctor and Wilf must fight alone. Sacrifices must be made, and the deadly prophecy warns: "He will knock four times."

Part One
A voice narrates the opening of the episode: "It is said that in the final days of planet Earth, everyone had bad dreams." On Earth, Wilfred Mott, entering a church, has a vision of the Master laughing maniacally. Inside, he notices a stained-glass panel with the image of the TARDIS. A mysterious woman tells him the church was a monastery in the 13th century. It was attacked by a demon which was exorcised by a "sainted physician". When the woman suggests that the physician is returning, Wilf says it would make his Christmas and turns to find she has vanished. He has another vision of the Master laughing, startling him.

In the 43rd century, the Doctor arrives on the Ood Sphere. He is greeting by Ood Sigma, whom he tries to make laugh by locking his TARDIS like an earth car. The Doctor is distracted by the marvellous city the Ood have built. When Sigma says it took a hundred years, the Doctor remarks it is too soon for them to have the technology. Sigma takes the Doctor to the Ood Elders, who show him visions of the Master returning. It's impossible; he saw his wife Lucy shoot him and he burned the corpse himself. The Ood show him an old woman taking the Master's ring and warn the Doctor of a greater danger returning from the darkness; its return precedes 'the End of Time itself'. Other visions are a frightened Wilfred and a "King in his Counting House". The Doctor rushes to Earth in the TARDIS.

The scene shifts to Lucy Saxon, locked in Broadfell Prison ever since she murdered her husband. One of her warders is Miss Trefusis, the woman who retrieved the Master's ring. On Christmas Eve, the prison Governor brings Lucy to a chamber; most of the staff are fanatical disciples of the Master who have worked since his death to bring about his resurrection. With the ring, a biometric imprint taken from Lucy and the sacrifice of the cultists' lives, the Master is reborn in a swirl of energy. However, Lucy and some other warders have prepared for this. She hurls a potion at the Master. There is an explosion.

The Doctor arrives the following day, too late. The prison is obliterated, but the Master had survived. As a result of Lucy's potion, he has supernatural speed, agility and can generate electrical bolts as weapons, but his life force is in a state of constant depletion. He is unendingly hungry for any food he can find and drains the vitality of homeless people on a desolate construction site.

The Doctor tracks the Master to a junkyard. The Master taunts him by beating a trashcan to a four-stroke beat, then leads him on a chase through the junkyard. Wilf scours London for the Doctor with other pensioners, calling themselves the "Silver Cloak" and finds him. After retreating to a cafe with him, the Doctor tells him a prophecy of his death. They notice Donna Noble standing outside, arguing with a police officer over her ticketed car. She's now engaged to Shaun Temple. Wilf pleads with the Doctor to at least go up to her and say hello to her. The Doctor reminds him that if Donna remembers him for even a second, she will die.

The narrator, his face revealed, speaks of the passage of Christmas Eve into Christmas Day; the players are moving into their final positions.

Finding the Master again, the Doctor discovers the drumming in his head is not a symptom of insanity, but real. Troops appears, sedating and kidnapping the Master and taking him to the mansion of billionaire Joshua Naismith. Back at Wilfred's house, Donna's fiancé, Shaun Temple arrives. As Wilf tries to watch the Queen's Christmas speech, mysterious woman interrupts the broadcast, ordering him to take arms; she also advises him not to tell the Doctor of what has happened, if his live is to be saved. Wilf takes his old service revolver 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 Donna bought the book as a present because her Time Lord subconsciousness is reaching out,. They immediately set a course for Naismith's estate, despite Sylvia's protests. In the TARDIS, Wilf asks the Doctor why he can't go back to yesterday and catch the Master; the Doctor says 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 can heal injuries and, Naismith hopes, offer life everlasting. He acquired the Gate after Torchwood's fall. Wanting immortality for his daughter, Naismith enlists the assistance of the Master to mend the malfunctioning Gate.

The Doctor and Wilf arrive at the Naismith estate and hide the TARDIS one second out of sync, so the Master can't get to it. In the basement, they discover two of Naismith's staff, Addams and Rossiter are undercover Vinvocci, disguised with shimmers as human; that the Doctor can see through the shimmers and deactivates them with his sonic screwdriver. The Vinvocci explain the Immortality Gate is a medical device that heals lifeforms across entire planets, using a genetic template. The Doctor rushes upstairs, but is too late to stop the Master from escaping his captors and jumping into the gate. Every single human on Earth sees the Master in their minds. The Master had modified the Gate to transmit his own genetic template across the entire planet, transforming every human on Earth into a clone of himself, save Wilf behind a radiation shield and Donna, immune due to her half-Time Lord mind.

Donna witnesses her mother and her fiancé turn into clones of the Master. She starts to remember everything that was erased from her mind. As the Master steps out of the gateway he tells the Doctor that the human race was always the Doctor's favourite, but it now exists no more, having been replaced with "The Master Race".

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

Part Two
On a devastated Gallifrey, on the last day of the Time War, the Time Lord Council has foreseen that the Eighth Doctor, in possession of something called "The Moment ", will end the war by destroying the Daleks and Gallifrey. At the heart of the Time War, billions are dying, being resurrected and dying repeatedly. The never-ending carnage is a travesty of life. One asks Rassillon to end the war once and for all. He kills her with his gauntlet. He will not allow himself or his race to die. Time Lord Council concocts a plan which involves retroactively implanting a link to the Master during his early childhood: the four-beat drum rhythm that has tormented him all his life. They next send a Gallifreyan "Whitepoint Star" diamond to Earth as a more physical, link. This will let the Time Lords escape from the Time Lock, and their impending destruction at the hands of the Doctor.

On Earth, the Master has the Doctor and Wilfred bound. No one but the Master Race exists on Earth. Wilf's mobile phone rings. The Master finds the phone, receiving a call from Donna. The Master hears Donna's voice, confused over her family and everyone else changing. Suspicious, the Master demands to know why Donna didn't change. Wilfred reluctantly admits the metacrisis that made her part Time Lord. The Master sneers "He does love playing with Earth girls!", then orders his copies to take her down. Donna is cornered by the Master Race. Even worse, she is starting to remember her adventures with the Doctor. Instead of burning up, she emits a heat pulse that knocks everyone unconscious, including herself. Hearing nothing and seeing the Doctor smile, the Master removes his mouth gag. The Doctor left Donna, his best friend, with a defence mechanism in case this happened.

The Master realises that the four-drum beat sound is from across time itself. He demands to know where the TARDIS is, threatening to kill Wilfred. The Doctor notes "you know the most amazing thing about you is that after all this time, you're still bone dead stupid." The Doctor then points out that even with six billion pairs of eyes serving him, the Master has failed to notice that the guard next to the Master is one inch too tall. The guard hits him in the head with the rifle, knocking him down. The guard is Rossiter. Addams rushes in and urges her partner to get the two men out of the mansion. Rossiter, unable to free the Doctor from the chair he is strapped to, is forced to wheel the chair down several flights of stairs, prompting the Doctor to note this as the worst rescue ever.

From the basement, the group teleport to the orbiting Vinvocci ship, narrowly escaping the Master and his guards. 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 asks for directions to the bridge; the Master has every missile on the planet ready to fire. When they arrive, the Vinvocci are only concerned with leaving, so the Doctor destroys the ship's systems to prevent their detection, leaving them dead in orbit. As the Doctor begins repairing the systems, Wilfred sees the mysterious woman again, who instructs him to give his gun to the Doctor.

Meanwhilee, 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 talks to him about many things and tries to have the Doctor take the gun to save himself by killing the Master. The Doctor refuses and Wilf begins to cry from his fruitless efforts, prompting the Doctor to hug him. A broadcast from the Master reaches the ship; 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 repaired the ship, but Adams will not have them going to earth. They Doctor takes control of the ship and speeding towards Earth. Rossitor and Wilf take charge of the asteroid lasers and blast away the missiles the Master has launched at them. Addams plots a course for Naismish's mansion and the Doctor jumps from the ship, crashing through the skylight and into the Immortality Gate room.

He is too late to stop the Master from bringing the Time Lords back. Not only is the Master in the room, but so are the Time Lord Council. The Master intends to implant himself in every Time Lord, but Rassillon uses his gauntlet to restore humanityl. The President tells the humans present to kneel as "the ascent" begins. The Master is confused; the Doctor angrily 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" is returning.

Wilf has returned to help the Doctor, but frees a trapped man in the control booth, trapping himself. The Master believes it wounderful the Time Lords are restored to the universe, but the Doctor says with the Time Lock broken, all the other horrors from 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. The Master delights at the thought of such chaos but the Doctor tells him even the Time Lords can't survive such an onslaught.

Rassillon reveals they had planned for this since the Time War. All creation and all of time will be destroyed and the Time Lords will ascend to a higher form of existence. becoming pure consciousness. The paradox will rip the Time Vortex apart. The Master asks to join them, but the President disgustedly refuses him.

Rassillon prepares to kill the Master when the Doctor pulls out Wilf's gun. He aims at the President, and the Master goads him on, telling him to kill the President and claim Gallifrey. At this, the Doctor spins and aims at the Master. 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 to the Time Lock. He points out that killing the President would have the same effect. As the Doctor frets on what to do, Rassillont sneers. "The final act of your life is murder. But which one of us?"

Tthe Doctor makes eye contact with one of the "disgraced" Time Lords kneeling behind the Lord President. She is the woman that Wilfred had seen. She nods solemnly to the Doctor and behind him. The Doctor aims at the Master once again.

As the Master's face falls, the Doctor says "Get out of the way." The Master jumps away from the Whitepoint diamond. The Doctor shoots it, ordering the Time Lords back into hell.

Gallifrey vanishes back into the Time Lock. Rassilon refuses to die alone and prepares to kill the Doctor, but the Master orders him to get out of the way and attacks Rassilon with his electric powers. 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 Gallifrey are gone.

The Doctor struggles to his feet, not quite believing he has survived. He smiles happily. safe, then his face changes to shock as he hears four hesitant knocks portending his death. Wilfred is trapped in a radiation containment device and can only be released at the cost of the Doctor's own life. After moaning that this is his reward, he concludes he has lived too long. Despite Wilfred's protests, the Doctor releases him and enters the containment device, receiving a massive level of radiation poisoning.

For a few seconds, the Doctor thinks he has survived even this. Then the effects on his body show his regeneration has started. It is a slow one. 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 tto many places. He saves Martha and Mickey, who are now married, from a Sontaran and Luke Smith from being hit by a car; he exchanges a meaningful look with Sarah Jane and goes to an alien bar to connect Captain Jack with Alonso Frame. Afterwards, he visits a book signing of A Journal of Impossible Things by Verity Newman, Joan Redfern's great-granddaughter. He pays a visit to Donna Noble's wedding, where he gives Wilf and Sylvia the gift of a winning lottery ticket to pass on to her.

Finally, the Doctor returns to the Powell Estate on New Year's Day 2005. Hidden in the shadows, he tells young Rose that she will have a great year. As she leaves smiling, the pain of regeneration sets in. The Doctor trudges towards the TARDIS, but collapses in the street.

Ood Sigma appears to him to tell him that the entire Universe will sing him to "his sleep". The Doctor picks himself up and staggers to the TARDIS as Sigma cotinues "This song is ending, but the story never ends."

The Doctor enters the TARDIS, tossing his coat on one of the coral structures and notices regeneration energy is coming out of his hand. He sets the TARDIS off on course for space as he circles the console. He says "I don't want to go." Golden energy radiate from his hand and head as he breathes heavily. He stretches his arms to regenerate into the Eleventh Doctor.

The delayed regeneration occurs in an unusually violent manner. The regernation energies shatter the TARDIS windows and set the console room ablaze, destroying a columns 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.

Once he does notice, he delights in the chaos. As the TARDIS plummets towards Earth, he whoops happily, grabs the console and shouts "GERONIMO!!!!"

The Doctor

 * In the first part, one of the things the Tenth Doctor lists he did instead of rushing to meet Ood Sigma is an implied marriage with Elizabeth I. He also implies that one of her nicknames 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 - at that time he had no idea why she was so angry with him, but couldn't wait to find out. Liz 10 later said that the nickname he sullied was "the Virgin Queen." (DW: The Beast Below)
 * 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. He did it again in DW: A Christmas Carol, or at least manipulated the outcome of the lottery so Kazran Sardick's servants and Nanny would leave. When confronted with the fact there is no lottery, he just say it's "lucky".
 * 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.
 * The Doctor mentions "then I got worse. Tricking others into taking their own (lives)." This is a reference to his seventh incarnation, where he was a master maniulator and keen strategist. (DW: Remembrance of the Daleks, The Curse of Fenric)

Individuals

 * Netty, a character from NSA: Beautiful Chaos, is referred to as a member of the Silver Cloak.
 * "Jimbo", previously mentioned by Clare Pope in DW: Partners in Crime, was mentioned in this episode by Jackie Tyler when the Doctor travelled back to 1 January 2005, to say his farewells.
 * Joshua Naismith has a book titled Fighting the Future, 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. In DW: Human Nature the Doctor, in 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 narrator is Rassilon.
 * The Woman's identity is not revealed, leaving speculation as to her identity.
 * 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 the Last Day of the Time War, before the Doctor destroys Gallifrey.

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 three 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 indirectly caused the Doctor to 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 also 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.

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 in Doctor Who 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 seventy-five minutes, four minutes longer than DW: Voyage of the Damned. It is the new f third longest single episode, behind the ninety-minute DW: The Five Doctors and the eighty-five-minute DW: Doctor Who.
 * The End of Time marked the last appearance of Elisabeth Sladen as Sarah Jane Smith in Doctor Who. She died on 19 April 2011.
 * With this, his final Doctor Who story to date, 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 (except for a flashback in DW: The Sound of Drums) since DW: The Trial of a Time Lord in 1986.
 * This is a second time that a Sontaran has appeared as a cameo in a regeneration story. The first was 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 few Doctor Who stories to feature narration. However, in this case it is revealed that the "narration" is 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 also 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's personal timeline, the events of that story occur before The End of Time.
 * 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 aborted 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).
 * 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 forty-eight-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.
 * Jessica Hynes's scene as Verity Newman was the first scene of this episode to be filmed (the scene was brought forward to accomodate Hynes's schedule, as she had just been cast in a Broadway play).

Ratings

 * Part 1 - 11.57 Million - According to BARB.
 * Part 2 - 12.27 million - According to BARB.
 * In America, three broadcasts of Part 2 garnered a combined total of 1.42 million viewers, a record for BBC America.

Filming locations

 * Tredegar House, Newport.

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). This was proved false; not only did the two appear, but so 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." B oth characters survived.
 * It was rumoured that Harriet Jones would re-appear. 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 II, who according to official series information had become Lord President of Gallifrey as the Time War broke out; this was taken down shortly after it was posted. In the episode commentary Julie Gardner 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

 * After principal photography had wrapped, the production team decided to change the Vinvocci's appearence. They had originally envisaged that the race would only be partially green. The only solution was to digitally composite a more complete green, and this necessitated frame-by-frame colouring of the Vinvocci scenes. At some points in the episodes this is noticable, for example 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
 * During the first time where Will is in the glass cabinet, in the close up his phone is to his head, yet in the long shots both his hands are against the glass.
 * When the Doctor goes to get A Journal of Impossible Things signed, Jessica Hynes 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 its 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 a hundred 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 "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, who was the Master.
 * 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 DWA: 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).
 * This episode is referenced in DW: Death Is the Only Answer.

'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 a hundred forty 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.
