The Eleventh Hour (TV story)

The Eleventh Hour was the first episode of the fifth series of BBC Wales Doctor Who. It featured the debut of Karen Gillan as new companion Amy Pond and Arthur Darvill as recurring character, Rory Williams.

Though not the first episode filmed of the 2010 series, it was nevertheless the public's first full exposure to a new production ethos, as shaped by then-new executive producers Steven Moffatt, Piers Wenger, and Beth Willis. It was also the public's first exposure to director Adam Smith's work on a Doctor Who universe programme.

The episode was extensively previewed prior to broadcast, with special screenings in several British cities as part of a special promotional tour at the end of March 2010, and special pre-broadcast screenings on both the east and west coasts of the United States. The first minute of the episode was released as a special preview on the digital Red Button service in the week prior to its first BBC One broadcast.

Synopsis
The Doctor has regenerated into a brand new man, but danger strikes before he can even recover. With the TARDIS wrecked, and the sonic screwdriver destroyed, the new Doctor has just 20 minutes to save the whole world - and only Amy Pond to help him.

Plot
After sustaining major damage from the Tenth Doctor's regeneration into the Eleventh Doctor, the TARDIS is flying wildly as it crashes through the London night sky in the 21st century. An explosion on the console causes the doors to unlock and the Doctor is barely hanging on to the edge of the entrance. As he tries to get back in, the Doctor notices the TARDIS is steadily heading towards Big Ben. Using his sonic screwdriver, the Doctor manages to divert the direction of the crashing TARDIS upwards. As he manages to pull himself in and shut the doors, the Doctor sighs a heavy breath of relief. But the relief doesn't last long as another explosion spins the TARDIS wildly into the distance as it begins heading backwards in time.

At Easter time in 1996, a young Scottish girl with red hair prays to Santa in her bedroom. There is a crack in her wall and she wants it mended. Suddenly, she hears the noise of the incoming TARDIS as it crashes with a loud thud in the garden. She runs over to the window and sees the TARDIS has crashed on its side in her garden shed. The young girl, Amelia, comes out to investigate. The TARDIS doors fly open and the Doctor pulls himself out of the TARDIS with a grappling hook hooked to a near by wheel barrel. The Doctor, now with his clothes ruined due to the crash asks her for an apple because his regeneration's after effects are giving him a craving. Wondering why the Doctor is so battered, Amelia asks what happened. The Doctor explains he crashed and fell all the way into the TARDIS library, but he's soaking wet. Amelia asks why he's wet and the Doctor explains he fell into the swimming pool. She asks why he's contradicting himself, but the Doctor tells her the pool is in the library to clear up confusion. She asks if he's a police man come to investigate the crack in her wall and the Doctor panics, asking if she called one. The Doctor spasms from his regeneration and falls to the ground, explaining this is perfectly normal for him at the moment. As regenerative energy leaves him, the Doctor asks Amelia if the crack in her wall scares her. She answers yes. The Doctor pulls himself up and introduces himself, but soon walks into a tree by accident because his steering is a bit off. They head inside and Amelia gives him an apple. The Doctor tries it and spits it out, wondering what it is. Amelia tells him its what he asked for and the Doctor explains that he has a new mouth, so there are new rules on what he's supposed to like. The Doctor tries others of his previous incarnation's favorites-- ranging from apples, yoghurt, bacon, beans and buttered bread. He hates them all, but at the last minute realizes what he likes in this incarnation: fish fingers and custard. The Doctor dines with Amelia and asks her why her parents haven't come down to investigate his crash. Amelia explains she doesn't have parents now and lives with her aunt Sharon. The Doctor is surprised by how Amelia is left alone. Amelia tells him that she's not scared of being alone. The Doctor tells her that if she's not scared of that or of a strange man who climbed out of a box that fell from the sky who's eating "fish custard" with her, then she must have one hell of a scary crack in her wall.

The Doctor then goes and investigates the crack in Amelia's wall. He quickly deduces that it is a crack in time and space after reading the scan he took with his sonic screwdriver. Listening with a cup pressed to the wall, he hears a voice saying "Prisoner Zero has escaped". He presumes that there is a prison on the other side of this crack with one of its inmates missing. To close the crack, the Doctor uses his screwdriver to fully open the crack, as he knows that by opening it, it will soon close itself, sealing itself at the same time. While it's open, the Doctor calls through, and a giant eyeball appears. It sends some blue energy through, which seems to zoom towards the Doctor's pocket. The crack then seals. The Doctor pulls his psychic paper out of his pocket and sees the words 'Prisoner Zero has escaped' written on it. He guesses that he has been sent this, because Prisoner Zero escaped through the crack because it acted like a wormhole. The Doctor investigates the corridor and senses he's missing something, on the corner of his eye. Just before he spots a room, he hears the cloister bells from the TARDIS, warning that the engines are going to overload from the crash. The Doctor then goes back to the TARDIS in an attempt to fix it, promising Amelia to return in five minutes, as a quick trip to the future will help fix the engines and then promptly de-materialises. An excited Amelia goes to pack her things, not noticing that the door the Doctor was about to discover has mysteriously opened.

The Doctor once again shows up at the bottom of Amelia's garden, but a bit late since its day time, and runs into Amelia's house, exclaiming that he's figured out what he was missing and that Amelia's life is in danger. He is looking around the house when someone comes up behind him and whacks him on the head with a cricket bat. When he wakes - hand-cuffed to a radiator - the Doctor is confronted by a young woman dressed in a police uniform. When the Doctor asks about Amelia Pond, the woman tells him that Amelia hasn't lived in the house for six months, and that she lives here now. The Doctor asks her to count the number of rooms on the floor. She counts five, but the Doctor reveals that there are six as one of them is protected by a perception filter so that no-one without a trained eye can see it. The woman is shocked at this and investigates the room, ignoring the Doctor's warnings not to. The Doctor even comments to himself he has an ignorable face again. In the room, she finds the sonic screwdriver on the table as it rolled under the door, but is stuck to a table by gooey saliva. She picks it up and comes face to face with Prisoner Zero, seemingly in its natural form, as a floating eel-like creature. Startled, she runs back to the Doctor and gives him his sonic screwdriver.

The Doctor locks the door and tries to free himself. Prisoner Zero breaks through the door and emerges as a human with a dog. However, the creature doesn't seem to be able to copy two voices at once, and so both the human mouth and the dog mouth bark. While trying to keep the creature at bay, he says that the policewoman had called for back up. Unfortunately, the woman, not realizing that the Doctor is trying to gain time, tells him that the radio was fake, she hadn't called for backup, and she isn't a police woman, but a kiss-o-gram. She then whips of her police hat, revealing long bright red hair. The Atraxi captain is then heard saying "Attention Prisoner Zero the human residence is surrounded" followed by "Prisoner Zero will vacate the human residence or the human residence will be incinerated" and keeps repeating it. Back at the local hospital several patients in comas keep repeating one word: "Doctor". One of the people in a coma is a direct double of the form that Prisoner Zero has taken.

The Doctor and the woman go outside to the TARDIS. However the Doctor can't open it because it's repairing itself. He then notices the shed which he had previously smashed when he had crash-landed. He licks it and (using an ability he seems to have inherited from his previous self) deduces the shed is twelve years old. He asks the woman why she had said six months had passed, when in fact twelve years had. In reply, she angrily yells "Why did you say five minutes!?" - in a Scottish accent. At this point the Doctor realizes that the young woman is adult Amelia Pond, who is exceptionally embittered and angry about the Doctor leaving her all those years ago and the resulting psychological trauma it caused her. Prisoner Zero barks at the entrance and they flee into the street, where they discover that the message from the Atraxi is repeated over and over again, on all wavelengths, throughout the world. The Doctor realizes this means that when the Atraxi are saying that they are going to incinerate the human residence, the human residence is not Amelia's house, but the Earth.

The Doctor and Amelia investigate the transmissions, which are being broadcast across the globe, entering the home of Amelia's friend Jeff Angelo and his grandmother, They both recognize the "Raggedy Doctor" from the drawings Amelia did as a child. While in the Angelo's home, Amelia also reveals that she is now calling herself Amy.

The two reappear on the green. The Doctor wonders why a duck pond hasn't any ducks as he spasms again, falling to the ground. The Atraxi put the earth in a forcefield, preparing to boil it. The Doctor recovers and notices a nurse taking a picture of prisoner zero in the near by park instead of the sun that's being obscured by the forcefield. The Doctor proudly announces he can save the world and tells Amy to help him or run home and say good-bye to loved ones. A car pulls up and Amy slams the Doctor's tie in the door, demanding to know his identity. The Doctor persuades her to trust him by showing her the apple she gave him when she was seven, still fresh. Amy releases the Doctor's tie and they run into the park.

The Doctor takes the nurse's cell phone and asks why he was taking that photo. Amy comes up behind the nurse and she introduces him as her "sort of boyfriend", Rory Williams. As Rory babbles that the Doctor shouldn't be there, the Doctor has run out of patience and holds Rory by the collar of his shirt, asking his question again. Rory explains that the man Prisoner Zero is disguised as can't be there because he's in the hospital in a coma. The Doctor explains that Prisoner Zero put people in comas through psychic links in order to gain disguises to walk around town in to avoid the Atraxi's attention. Confronting Prisoner Zero, the Doctor tells him that the Atraxi, who've sent a scout into the town, are scanning for no-terrestrial technology. The Doctor uses his sonic screwdriver to attract the attention of the Atraxi. With light fixtures and telephone booths exploding, his plan seems to be working, until the already-damaged screwdriver overloads and burns out into a useless piece of charred metal. The Atraxi scout flies back into space, with the Doctor angry they're so thick not to notice the chaos he caused.

With the distraction gone, Prisoner Zero escapes into a sewer and disappears. Figuring that it would take approximately twenty minutes for the Atraxi to power up their weapons and then incinerate the planet, the Doctor rushes Plan B into action. He sends Rory and Amy to the hospital to clear out the coma ward, but Prisoner Zero beat them there and is killing all the conscious people in the ward. The Doctor heads to Jeff's room and uses his laptop to talk with all the "big boys": NASA, Tokyo Space Center, Patrick Moore, etc. Using Rory's phone, he writes a virus to turn every single digital display in the world into a list of zeros, uploads it to the web via a laptop, telling them to get it spread across the world. At the hospital, Amy and Rory have gotten passed security thanks to her kiss-o-gram outfit. They meet a mother and her two daughters who survived Prisoner Zero's attack on the ward. Amy phones the Doctor, who has "commended" a fire engine to reach the hospital, telling him Prisoner Zero beat them there. The Doctor warns them to leave now, but they see one of the daughters talking in the mother's voice. Prisoner Zero apologizes for getting it wrong, but then snarls as it chases Amy and Rory into the room the coma patients are in. Prisoner Zero taunts Amy for her belief in the Doctor and that nothing can save her this time.

The Doctor suddenly rams the ladder of the firetruck into the window of the ward and asks Prisoner Zero to peacefully surrender by removing its disguise. Not complying, Prisoner Zero forces the Doctor's hand as his virus takes hold on the clock behind them and all around the world for all digital devices. The Doctor tells him Rory took pictures of all his forms and uploads them to the Atraxi, but Prisoner Zero isn't fazed and uses the unused link it formed with Amy to take the form of the Doctor. The Doctor wonders who Prisoner Zero turned into and is told by Rory that's what he looks like now. Prisoner Zero tells them, its not copying JUST the Doctor, but Amelia holding his hand all those years ago. Reading, Amy's mind, Prisoner Zero tells the Doctor he's been a disappointment to Amy and that she's still a child inside. The Doctor uses his telepathy to have Amy dream of Prisoner Zero's true form. Angry, Prisoner Zero reverts and is about to attack the Doctor, but the Atraxi catch him in a paralyzing light and begin to teleport him away. Prisoner Zero snarls ominously at the Doctor "The Pandorica will open. Silence will fall... Silence, Doctor. Silence will fall".

With the threat ended, Amy awakes. The Doctor angry calls the Atraxi back to the roof under rules of the Shadow Proclamation and heads off to face them. Along the way, the Doctor stops in the locker room for the hospital staff and begins undressing as he decides on what clothes to take. The Doctor explains that "if I'm going to save the world, I need a decent shirt." Rory complains about this, but gives up. They go to the roof, were the Doctor tells the Atraxi earth is a level 5 planet guilty of no crimes against or a threat to the Atraxi. Smugly, the Doctor ask the Atraxi if earth is protected and the Atraxi shows a projection of several enemies that attacked earth from the '70s -'10s as the Doctor asks it what happened to them. It shows all ten of the Doctor's past lives. The Doctor tells the Atraxi he's the new doctor and to run away. It complies as the Doctor notices his key is glowing - the TARDIS has recovered and is waiting for him. Suddenly bursting with excitement, the Doctor, dashes off to the rebuilt TARDIS to see what is in store for him, and his eyes open with wonder as he beholds the newly repaired console room. Amy, realizing that he is gone, runs back to her garden followed by Rory, only to find the TARDIS fading away. She is clearly upset although she sheds no tears.

Two years later, Amy Pond, dreaming of her younger self waiting for the Doctor to return, is suddenly startled awake by the sound of the TARDIS returning. Running out of the house in her night clothes, she finds the Doctor standing in the garden with the TARDIS. He said that he took the TARDIS for a "quick trip to the moon" to break in the engines. Amy angrily informs him of the amount of time (two years) she has been waiting for him since his last visit. The Doctor states that she's waited long enough, and welcomes her to join him as a companion. Highly skeptical after waiting all this time, she initially refuses, but changes her mind when the Doctor snaps his fingers to open the TARDIS door, and Amy sees the TARDIS's interior for the first time. Amy forces the Doctor to promise to bring her back to Leadworth by tomorrow morning. Though she doesn't give an answer as to why, the Doctor activates the controls and they vanish into the Time Vortex. The reason becomes clear soon enough to the audience, though; her bedroom is revealed to contain a few slightly packed suitcases.... and a wedding dress hanging on the wardrobe door.

The Doctor

 * The Doctor says "What? What? What?" and "Wibbly wobbly, timey wimey" much like his previous incarnation.
 * The Doctor opens the TARDIS doors with a snap of his fingers for the first time since Forest of the Dead. According to River Song in the same episode, he will begin to do so regularly at some point in the future.
 * When Jeff states "You can't just hack in on a call like that." the Doctor responds with "Can't I?". This is the Fourth Doctor's same response and mannerism to Sarah Jane's and the Brigadier's protests when he first regenerates.
 * Perhaps due to his new appearance, the Doctor finds it necessary to prove to the online conference that he has the credentials to solve the problem, despite the fact the name "The Doctor" would have been well-known in these circles at this time (per DW: The Christmas Invasion, and other events).
 * The Doctor mentions "cowboys," a phrase used by his previous incarnation in DW: The Girl in the Fireplace.
 * The Doctor drives a Fire Engine.
 * The Doctor calls the TARDIS "oh, you sexy thing" and "dear", possibly referring to the fact he has known it for so long and it's very close to him.

Food and Beverages

 * The Doctor craved many different types of foods whilst still undergoing regeneration. He attempted to try many until he finally decided which one he liked. The Doctor didn't like apples, yoghurt, bacon, beans or bread & butter, and rejected carrots without even trying them, but did like fish fingers and custard, a combination he dubbed &quot;fish custard&quot;.

Galactic Law

 * Article 57 of the Shadow Proclamation is cited by the Doctor against the Atraxi, similar to when he cited it against Matron Cofelia in DW: Partners in Crime.

Earth locations

 * Gloucester is 30 minutes away from Leadworth.

Science and Maths

 * The Doctor uploads the "real" proof of Fermat's theorem, the formula for faster-than-light travel (albeit using "two diagrams and a joke"), and an explanation for why electrons have mass as a way to prove to the experts on the secure video conference that they should trust his advice about how to deal with the Atraxi threat.
 * The Doctor refers to Jordrell Bank Centre for Astrophysics, NASA, and the Tokyo Space Centre as three of "the big boys", as well as Sir Patrick Moore (playing himself). Unmentioned by the Doctor but shown on the conference screen are the ESA (European Space Agency) and CSIRO (Australia's Commonwealth Scientific and Industrial Research Organisation).

Music and Songs

 * The Ice-Cream man mentions that the song that was originally supposed to be playing from the Ice-cream truck's speakers was meant to be 'Claire De Lune' before the Atraxi had hijacked it.

Technology

 * The Doctor notes there is a perception filter around the door so that it is only visible out of the corner of Amy and his eyes.

Theories and concepts

 * Prisoner Zero mentions that the Pandorica will open.

Story notes

 * The working title for this episode was The Doctor Returns.
 * Matt Smith revealed that there are five things in this story to look out for over the course of the series, the cracks being one of the five things.
 * The opening scene, which was released on BBC Red Button, was actually a pick-up. Not originally included in the final shooting script of the episode, it was written months after principal photography had wrapped on the episode. It technically had its own script, subtitled "Opening Sequence". At least two drafts were written, with the second being dated 17th December 2009. The sequence was in fact its own production. Unlike the episode proper, its producer was Nikki Wilson, its director was Jonny Campbell, and its director of photography was Tony Slater-Ling. Wilson received a credit of "special thanks" in the end credits. The involvement of Campbell and Slater-Ling were established by behind-the-scenes footage of clapperboards. (WC: Doctor Who Video Explorer)
 * According to Russell T Davies in Doctor Who: The Writer's Tale, Moffat informed him in January 2008 that he had begun writing the first episode of Series 5.
 * This is the only televised story starring a single incarnation of the Doctor to refer to the number of that incarnation in its title.
 * The episode included a sequence showing all previous ten incarnations of the Doctor. The vision of the Tenth Doctor is from DW: The Family of Blood.
 * The episode introduces a new Doctor Who theme arrangement, an unprecedented third by Murray Gold (not counting several other closing-credit and non-series arrangements). A new opening titles sequence is also introduced, along with the first on-screen use of a new Doctor Who logo. Other cosmetic changes as of this episode include a new TARDIS interior design, slight modifications to its exterior, and the introduction of a new sonic screwdriver.
 * This story reveals that at least some sonic screwdrivers are grown/built by the TARDIS.
 * Amy Pond is the first modern Earth companion since the series' revival to not be from London. In the Confidential for this episode, Steven Moffat says that London-set stories had become a cliché and this was an attempt to avoid it.
 * The TARDIS scene in which the characters are viewed through the central column mirror those seen in the film.
 * Prisoner Zero states that "The Pandorica will open", and repeats "Silence will fall".
 * In the final scene, the Doctor is standing next to a monitor in the TARDIS that shows a waveform. The waveform appears to be the same shape as the crack in Amy's wall.
 * To write the virus, the Doctor uses Rory's BlackBerry Storm (confirmed by Engadget-4/04/10).
 * The monitor in the new TARDIS console has a Magpie Electricals logo on it.
 * Like the Eleventh Doctor, the Tenth Doctor also had a distaste for certain foods: particularly pears. (DW: Human Nature/The Family of Blood)
 * Lots of speculation began concerning Rory William's 1990 badge date and how it conflicted with many things seen and heard on-screen (slim camera-phones, Facebook, Twitter, Bebo, and the very 2000s technology); however, Steven Moffat later confirmed that the badge date was a mistake that went unnoticed until after the episode aired. The year of this story was later confirmed in Flesh and Stone.
 * When the Doctor and Amy leave her yard in the TARDIS at the end of the episode, the clock in the TARDIS is shown changing from 11:59am to 12:00pm, despite the fact that it is clearly night outside. This would not usually be notable (this *is* Doctor Who), except that an identical effect is observed on the clock in Amy's bedroom at the end of DW Flesh and Stone. Also in the same episode, the Doctor confirms that they "had been gone five minutes"; yet the time is the same.
 * This is the first time the Doctor doesn't use a mirror to find out what he looked like after a regeneration (as part of one of Prisoner Zero's forms was him).
 * The Eleventh Doctor continues a long standing tradition (which has had a few exceptions) of performing a large portion his first episode in the costume of his previous incarnation, picking out his new costume at the end of the episode.
 * This episode aired on the same day as the K9 episode, The Korven was first broadcast on Disney XD in Britain. It also aired on the same day that Regeneration was first broadcast on Network Ten in Australia.
 * One clothing retailer reported that in the month following the airing of this episode, in which the Doctor declared that "bow ties are cool," its bow tie sales increased by 94%.

Production errors

 * In the opening scene, there are several errors.
 * When the the Doctor is hanging from the TARDIS across London, every wide shot shown depicts the TARDIS rotating, but whenever a close-up of the Doctor is shown, the background does not rotate.
 * When the camera initially looks down on the Doctor, the floor is at slightly different levels, but when it cuts to the Doctor pulling himself inside, the floor is all the same level.
 * The St. John's Ambulance logo is visible on the CGI wideshots of the TARDIS, yet on the live-action close-up, the doors remain as they have been since 2005.
 * On several occasions editor James Pearson mismatches footage of the same scene-parts, as recorded by different cameras or in different takes.
 * When the Doctor leaves Amelia for his TARDIS-stabilizing, five-minute hop into the future, Caitlin Blackwood's closeup shows her hair being whipped around by the TARDIS' departure. When Pearson immediately cuts to an over-the-shoulder shot of Blackwood watching the departure, her hair is totally unaffected.
 * During the Leadworth hospital rooftop scene, the Doctor progressively throws away a variety of neckties as he whittles the options down. The last of these neckties is yellow, which we see in a frontal mid-shot. When Pearson switches to footage taken from the side in a long shot, the tie is not present. When he again switches to the frontal mid-shot, the tie reappears. Later in the same scene, Pearson has a similar problem. The wide shot of the departing Atraxi vessel shows Smith reaching into his coat pocket for the TARDIS key. When Pearson cuts back to a close-up of Smith, he hasn't yet reached into his pocket, and it takes several seconds for him to complete the same action from that angle.The Doctor's hair switches from being swept back to hanging in front of his forehead. Several times when the hair is in front of his forehead, the number and size of strands also changes. Also, when he has Yoghurt smeared on his chin it vanishes after the shot changes.
 * When the Doctor slaps himself in the forehead exclaiming "I missed it! I saw it and I missed it!", he ends up with a red mark, but when the camera cuts to the close-up, the red mark has vanished.
 * In the final TARDIS scene, The Doctor obtains his new Sonic Screwdriver, throws it and pockets it. However, when Amy asks The Doctor "why her", when he responds we can see him still putting it in his pocket.
 * When Prisoner Zero takes the form of the mother with two daughters, the older, longer haired girl always appears to the right of the mother. When the Doctor crashes the fire engine's ladder through the window and Prisoner Zero looks on, the two girls have switched places.
 * When Prisoner Zero walks out of the "extra room" in Amy's house, the doorway that he eventually walks through has its door closed yet when we flick to Prisoner Zero looking at the Atraxi's voice booming out we see that the door has magically disappeared and Prisoner Zero walks through.
 * During the final scene inside the TARDIS we see close-up views of The Doctor's hands turning three joysticks and typing on the typewriter. You can clearly see that his tweed jacket has mysteriously changed pattern, becoming the pattern that is not shown again until Victory of the Daleks.
 * Some of the aliens shown in the Atraxi projection on the Leadworth hospital speech scene weren't encountered on Earth, like the Hath and Vashta Nerada, for example. Also, the image when the Cybermen crash through the window was from the Rise of the Cybermen which was in Pete's World, and not ours.
 * When the Atraxi is scanning the Doctor, the camera from behind shows his head tilted but when the camera view switches to in front of the Doctor, his head is straight up.
 * When the Atraxi first starts scanning the Doctor, from the camera behind the Doctor, the scanner light is halfway down his body, but when it switches to in front of him, it's just then going by his head.
 * When the Doctor rushes out to stabilize the TARDIS, Amelia says, "But, it's just a box. How can a box have engines?" The word engines is unusually loud.
 * When the Doctor is talking to the Atraxi on the roof of the Leadworth Hospital, he has a bunch of ties on his shoulder. The one he eventually chooses (a maroon bow tie) is never seen on his shoulder in the scene before he walks through the projection.
 * When Amelia talks about her four psychologists, her accent leads many people to hear the line "I kept fighting them" as "I kept biting them."

Continuity

 * The Doctor asks "Do I have a face that no one listens to? again," this is a reference to that the Doctor's companions never listen to him.
 * The majority of this episode takes place in 2008, with the final scene set 25th June, 2010. Amy is 21 at this time (established in Flesh and Stone)
 * This story continues the events seen at the end of DW: The End of Time with the TARDIS crashing towards Earth.
 * Perception filters have previously been mentioned/seen in reference to the TARDIS keys (DW: The Sound of Drums) and the Torchwood Three lift (TW: Everything Changes).
 * The Doctor uses the phrase "Wibbly Wobbly, Timey Wimey" which was first used by the Tenth Doctor in DW: Blink and again by both the Tenth and Fifth Doctors in DW: Time Crash.
 * The Doctor opens the TARDIS by clicking his fingers as he first did in DW: Forest of the Dead.
 * The Shadow Proclamation is again invoked in the first story of a new incarnation of the Doctor, as it had been in Rose and The Christmas Invasion.
 * Creatures that appeared in the projected image included the Cybus Cybermen (DW: Rise of the Cybermen), the Daleks (DW: Doomsday), a Pyrovile looking up (DW: The Fires of Pompeii), the Empress of the Racnoss (DW: The Runaway Bride), the Ood (DW: Planet of the Ood), the Hath (DW: The Doctor's Daughter), the Sontarans (DW: The Time Warrior), the Sea Devils (DW: The Sea Devils), the Sycorax (DW: The Christmas Invasion), a Reaper (DW: Father's Day) and a Vashta Nerada's victim (DW: Silence in the Library). The use of clips from The Time Warrior and The Sea Devils marks the first time "monster clips" from the 1963-89 series had been used in the revival.
 * The Doctor mentions that he got tired of travelling alone. (DW: Planet of the Dead; The Waters of Mars)
 * Images of all ten prior incarnations of the Doctor are also projected.
 * This is not the first time a newly-regenerated Doctor has taken new clothes from a hospital. The Third and Eighth did the same thing. (DW: Spearhead from Space; Doctor Who)
 * The Doctor's sonic screwdriver was previously destroyed in DW: Smith and Jones, a story which was also the first episode of a new series and also introduced a new companion, as well as in DW: The Visitation.
 * This story contains minor references to previous episodes written by Steven Moffat. Libraries are mentioned on numerous occasions, a potential reference to the two-parter DW Silence in the Library/Forest of the Dead. The concept of meeting a person at different points of their life - as the Doctor (accidentally) does with Amy Pond - was a major theme in The Girl in the Fireplace. Similarly, River Song also meets the Doctor at different points in his life. The Doctor also mentions 'Wibbly Wobbly, Timey Wimey', as he did in DW: Blink. The Doctor opens the TARDIS by snapping his fingers as he did in DW: Forest of the Dead. When Amy contradicts him after he tells Prisoner Zero she sent for backup, he refers to the deception as "a clever lie", the same phrase he retorted with after Donna challenged his claim that the two of them were safe from the Vashta Nerada.
 * The Doctor intending to return in 5 minutes and accidentally taking 12 years is similar to the first time he takes Rose home in DW: Aliens of London; however instead of taking 12 hours, it was 12 months.
 * When the Atraxi reference that the Doctor is not from Earth, he responds with "No, but I've put a lot of work into it." These are the same lines used in DW: The Curse of Fatal Death (also written by Moffat) with regards to the universe.
 * After witnessing the destruction of the Sycorax at the hands of Torchwood in The Christmas Invasion, the Doctor tells Harriet Jones that he "...told them this world was protected. I should have told them to run." This time, he does both.
 * The TARDIS' doors open outwards for the first time since Episode 1 of DW: The Ice Warriors.
 * Assuming that Amy is able to see the Atraxi projection of the Doctor's past incarnations, this makes her the first ongoing companion of the revival to see all the Doctor's past lives (Jackson Lake in DW: The Next Doctor saw a similar projection, but he was only a one-off companion).
 * The Doctor is knocked unconscious by Amy's cricket bat. In the novelisation for DW: The Power of the Daleks it was stated that were the Doctor rendered unconscious soon after regeneration the cycle might have started again. Fortunately, the Eleventh Doctor appears to avoid this complication.
 * The Doctor congratulates Prisoner Zero on "the perfect impersonation of yourself"; The Master gave Adric similar congratulations after he created an illusion of himself to fool Nyssa. (DW: Castrovalva)
 * The TARDIS previously "regenerated" in The Company of Friends.
 * The Doctor's rejection of carrots may be a callback to his sixth and seventh incarnation's dislike of carrot juice. (DW: Terror of the Vervoids, The Ultimate Foe, Time and the Rani)
 * When the Doctor tells Prisoner Zero to open a crack again to escape from the Atraxi, it says it didn't open the crack. When it finds out he doesn't know what the cracks are, it adopts a young girl's voice and says, "The Doctor in the TARDIS doesn't know. Doesn't know, doesn't know!" this is similar to what Angel Bob says in DW: Flesh and Stone Angel Bob's words were, "The Doctor in the TARDIS hasn't noticed."
 * When the Doctor leaves in his new TARDIS, there is lightning or electricity as is leaves, just as there was when it materialized in San Fransisco on the 30th December 1999. (DW: Doctor Who)

DVD/Blu-ray-exclusive scene
The 2010 DVD and Blu-ray release of the Complete Series 5 included an additional scene from The Eleventh Hour. Contrary to many reviews and video-sharing site repostings of the scene, it is not a deleted scene, but rather a scene shot specifically for the DVD/BD release sometime during the later stages of Series 5 production. The comedic scene links the events of The Eleventh Hour with that of The Beast Below as Amy endlessly hammers the Doctor with questions about the logistics of the TARDIS, as well as mocking his decision to wear a bow tie, even at one point wondering if it might be a "cry for help". The Doctor replies, "Bow ties are cool".

The scene ends with the Doctor playfully pushing Amy out into the air bubble surrounding the TARDIS, which leads directly into the first scene of The Beast Below in which Amy is seen floating above the TARDIS, the Doctor holding her by the ankle (although this is not clear to those viewing the scene without the benefit of knowing how The Beast Below begins).

International broadcasts
The Eleventh Hour received its international broadcast debut on 17th April 2010 when both BBC America in the US and Space in Canada broadcast it, followed by ABC1 in Australia on 18th April.

However, it had several pre-broadcast public screenings in North America prior to its official broadcast launch. On the west coast, it premièred on 3rd April at WonderCon in San Francisco. Its east coast debut was on 14th April 2010 at the Village East Cinema in Manhattan. This latter screening was sponsored by BBC America, and was attended by Matt Smith, Karen Gillan and Steven Moffat, who fielded questions after the showing. An additional showing occurred on 16th April at the C2E2 convention in Chicago. In addition there were also press screenings, such as the Canadian one held in Toronto 8th April after which Moffat participated in a Q&A via Skype.
