The Eleventh Hour (TV story)

The Eleventh Hour was the first episode of the fifth series of BBC Wales Doctor Who. It was Matt Smith's first full story as the Doctor, as well as the debut of Karen Gillan as new companion Amy Pond and Arthur Darvill as recurring character and future companion Rory Williams. It also sparked the beginning of a critical plot thread that trailed deep into the Eleventh Doctor's tenure with three words: "silence will fall". This was compounded by the mention of a Pandorica which was fated to open.

Though not the first episode of the 2010 series filmed, it was the public's first full exposure to a new production ethos, as shaped by new executive producers Steven Moffat, 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. A new title sequence by Framestore debuted with this episode, along with yet another Murray Gold theme arrangement. The theme change, however, garnered significant public backlash in the United Kingdom, forcing the Doctor Who production team to respond to criticism in a long segment on the public comment programme,.

The episode was extensively previewed before broadcast, with theatrical screenings in several British cities as part of a promotional tour at the end of March 2010, and on 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 a week before its first BBC One broadcast.

Synopsis
After a literally explosive regeneration, the brand new Eleventh Doctor survives a crash-landing to Earth. However, he has little time to recover. With a mysterious crack in a little girl's wall and a missing alien prisoner, the Doctor is in for an adventure. However, with the TARDIS damaged and the sonic screwdriver destroyed, can the Doctor capture the rogue alien before its jailers burn Earth to a crisp?

Plot
Suffering major damage after the Tenth Doctor's regeneration, the TARDIS flies wildly over London as it enters the atmosphere. An explosion on the console inside causes the doors to unlock and the new Doctor to fall out, barely hanging onto the edge of the entrance. He tries to pull himself up as the TARDIS momentarily stabilises, though it is still heading downwards. Getting halfway in, he notices the TARDIS is heading straight for Big Ben; using the sonic screwdriver, he diverts the TARDIS just enough to miss the clock tower's spire. Pulling himself back in and locking the doors behind him, the Doctor sighs in relief. However, another explosion throws him as the TARDIS spins madly off into the distance. In 1996, Amelia Pond prays to Santa Claus in her bedroom; a crack in her wall frightens her, and she wants him to send someone to mend it. Suddenly, a crash outside catches her attention, and running to look, she sees the TARDIS lying sideways in her back garden, having crushed her shed on landing. She thanks Santa, and goes to investigate. The TARDIS doors swing open, and a grappling hook flies out, hooking onto a wheelbarrow. A soaking-wet Doctor struggles to pull himself out. He asks for an apple as they're the only thing he can think of; his regeneration is giving him a craving, which he's never had before. As he starts climbing out, he has a look down into the TARDIS, explaining that he'd had to climb up from the library. When Amelia points out that he's soaking wet, the Doctor explains that the swimming pool is also in the library right now. The Doctor has a momentary spasm, causing him to fall to the ground before breathing out a stream of golden energy. She asks him who he is, but the Doctor doesn't know yet himself; he's "still cooking". Amelia tells him about the crack, and the Doctor introduces himself, informing her to do what he says and not wander off; he promptly walks into a tree and knocks himself down — "Early days. Steering's a bit off".

Inside, the Doctor tries eating an apple, but spits out the bite he took, saying it tastes terrible. He then requests yoghurt, but spits it out as well. Amelia is confused, as the Doctor had said it was his favourite. The Doctor explains, "New mouth, new rules".. More food follows: bacon ("Are you trying to poison me?"), baked beans (spit into the sink, saying, "Beans are evil; bad, bad beans"), bread and butter (after a hopeful smile, he ends up tossing the entire plate outside, and roaring, "And stay out!"). Searching Amelia's fridge, the Doctor rejects carrots ("Are you insane?") before find just what he needs: fish fingers and custard.

While the Doctor tries out his new delicacy, Amelia eats ice cream from the tub. The duo bonds. During their conversation, the Doctor discovers Amelia Pond — a great name, according to the Doctor, "like a name in a fairy tale" — is originally from Scotland, is orphaned, and lives with her Aunt Sharon. Upon learning that her aunt is out, the Doctor notes that because Amelia is neither afraid of him nor his strange arrival in her garden, it must be one hell of a scary crack in her wall. Amelia takes the Doctor up to her room to examine the crack in the wall. She also offers him an apple with a smiley face carved into it, like her mother used to make for her to help her like them. Upon inspecting the crack closer, the Doctor is astonished to hear a voice on the other side of the crack transmitting the message, "Prisoner Zero has escaped." Ascertaining that an alien prison lies on the other side of the crack, he opens it fully with the sonic screwdriver and is faced with the alien guard — which appears to be a giant eyeball — who sends him a message on the psychic paper before the crack shuts once more. The message reads the same thing: "Prisoner Zero has escaped." The Doctor, realising the prisoner has escaped through Amelia's bedroom, rushes out into the corridor to investigate and deduces that he's missing something out of the corner of his eye. Before he can discover it, though, the Cloister Bell chimes.

He rushes outside with Amelia, telling her that the TARDIS' engines are in danger of phasing out of existence. Amelia wonders how a box can have engines, and the Doctor tells her his TARDIS is a time machine. She asks to come with him, but the Doctor says it's too dangerous now, and he'll do so after taking a quick five-minute trip into the future to begin repairs. Yelling "Geronimo!", the Doctor jumps back into the TARDIS and it dematerialises before Amelia. Excited, the little girl returns to her bedroom to collect her things, not noticing that the door at the end of the corridor — the thing the Doctor was missing — has opened...

The Doctor returns to her garden in the daylight, realising that he has taken longer than promised; Amelia is no longer outside waiting for him. He rushes back into the house, having figured out what he was missing and knowing that Amelia's life is in danger. The Doctor tries opening the door at the end of the corridor with the sonic, yelling that Prisoner Zero is there with them. He suspects someone is behind him and turns around, only to be whacked on the head with a cricket bat.

Elsewhere, at the town hospital, nurse Rory Williams informs his supervisor, Dr Ramsden, that the coma patients have been calling out for her. She dismisses the idea, drawling that they are comatose. As she berates him, the patients repeatedly cry out "Doctor" much to her shock and horror.

The Doctor awakes to see he is handcuffed to a radiator; he is confronted by a young woman in a police uniform. He inquires where Amelia Pond is, only for the police woman to angrily inform him Amelia hasn't lived there for six months, and that she lives here now.

At the hospital, Rory and Ramsden examine the patients carefully, but they still appear to be in comas. Rory attempts to inform his supervisor of other suspicious circumstances pertaining to the coma patients, even proffering his phone with the suggestion that the pictures on it can prove his theory. She impatiently orders him to take some time off.

Back in Amelia's house, the Doctor orders her to count off all of the rooms on the floor; she counts five, but the Doctor quickly informs her that there are, in fact, six — one is hidden by a perception filter. Ignoring the Doctor's warnings, she enters the sixth room. The Doctor checks his pockets for the sonic, finding it's not with him. He yells for her to check and see if it's in there; it could've rolled under the door when she hit him. The sonic is there, but is stuck in a puddle of goo on the table. She yells to him that it "must have jumped on the table", making the Doctor order her to leave the room at once. The woman picks up the sonic, but senses something is in the room with her. The Doctor orders her not to try looking at it as it will kill her if she sees it. Despite the warning, the policewoman manages to trick Prisoner Zero into revealing himself, seeing it's a serpentine alien multi-form.

She runs back to the Doctor, closing the door behind her. The Doctor locks the door with the sonic and tries to free himself, but the sonic is damaged from the goo. The young woman asks if the door will hold Prisoner Zero, making the Doctor retort, "It's an alien multi-form from outer space; they're all terrified of wood!" Seeing a light coming from under the door, the policewoman asks what the alien is doing. The Doctor doesn't know, but tells her to run and radio for backup. However, the woman reveals herself to be a kissogram, whipping off her police hat to reveal long, red hair. Prisoner Zero breaks through the door, emerging as a man with a dog; both mouths bark, much to the Doctor's amusement as it's having trouble figuring out which mouths are supposed to make the correct sounds. He then wonders where he would have gotten the pattern from as it would need to form a psychic link with someone, which takes years. He informs the alien the young woman called for backup on her police radio, but she reminds him that she can't; the Doctor explains in annoyance it was a clever lie to save them. He then says that without any backup, they pose no threat.

The prison guard is heard transmitting from outside, repeating the same message over and over: "The human residence is surrounded. Prisoner Zero will vacate the human residence, or the human residence will be incinerated."

The Doctor finally succeeds in freeing himself, and orders the woman to run away while Prisoner Zero is looking around for the source of the broadcast. The Doctor tries opening the TARDIS for equipment, but the doors won't open as it's still repairing itself. Suddenly, the Doctor notices the shed in the backyard, remembering he wrecked it when he previously crash-landed in the backyard. Licking it, he realises this "new" shed is 12 years old. He turns to the woman, demanding to know why she told him six months when it had really been twelve years; she angrily demands to know, "Why did you say five minutes?!" in a Scottish accent. The Doctor can only ask, "What?" with increasing shock; the woman is Amelia Pond! Grabbing his arm, she pulls him out of the yard and towards town.

In town, the Doctor inquires why Amelia hit him with a cricket bat; she defends her action by explaining that their meeting led her to see four psychiatrists over the last 12 years. She bit them all when they told her he wasn't real. Their argument is cut short when they suddenly realise that the Atraxi message is broadcasting over all of the town's electronics, including cell phones, iPods, even the speaker of an ice cream van. The Doctor sees the Atraxi are not focused on simply Amelia's house as the "human residence", and immediately runs to the first house he sees with Amelia following.

The house belongs to Amelia's friend Jeff Angelo and his grandmother. The Doctor uses the psychic paper to pass himself off as a television repair man. Mrs Angelo thinks she's met the Doctor before, but the Doctor tells her it's not likely, seeing as he's got a new face on. The Doctor then examines the TV and radio stations around the world with help from his sonic screwdriver, and realises, to his horror, that the warning is being broadcast all over the world in every language. The human residence is not just Amelia's town, but the entire planet! The Doctor deduces that the Atraxi will need twenty minutes, prompting Amelia to ask what for. The Doctor says, "The end of the world". While the Doctor begins thinking of a plan, everyone else watches the Atraxi message replay on the television in disbelief. Above the Earth, the squad of Atraxi ships continue transmitting the message around the world as they search the planet for Prisoner Zero; incinerating Earth to be rid of the menace is a last resort. However, it would seem they will never be able to find it on their own as they keep resending the message.

Back on Earth, Jeff and his grandmother realise how they know the Doctor: he's the "Raggedy Doctor" that Amy used to draw cartoons of as a child. The Doctor is disappointed that, not only does she kiss people for a living, but she also dropped the name Amelia for Amy, citing its fairy tale quality — which the Doctor complimented on their last meeting — as its worst point.

The Doctor and Amy head to the town square, and the Doctor is annoyed to discover that Leadworth, where Amelia lives, has no technology to help him. In the middle of remarking about a duck pond without ducks, the Doctor suddenly convulses and falls to the ground, protesting that it is "too early" and he's "not ready yet". Suddenly, though, everything goes dark. The Atraxi have surrounded Earth in a force field to prepare the planet for boiling. Across the park, the Doctor notices Rory taking pictures of a man with a dog — whom the Doctor knows as Prisoner Zero — as opposed to the obscured sun, like everyone else.

The Doctor gleefully announces he can save the world and offers Amy a choice: she can run home and say goodbye to her loved ones, or help him. Amy opts for a different option entirely: she slams the Doctor up against a nearby car, and locks his tie in the door, trapping him. She demands to know who he is. The Doctor hands her the carved apple that she gave him when she was seven. He explains that he's a time traveller, and that everything he told her twelve years ago is true. The apple is the exact same one Amy gave him as a child, proving the Doctor is telling the truth. She releases the Doctor's tie and they run across the park to confront Rory.

Amy introduces Rory as her "sort of" boyfriend, but the Doctor is not interested. He takes Rory's cell phone, and demands to know why he was taking a picture of the man and dog rather than the sun. The Doctor gets an expected response: Rory tells him that the man can't be in the park because he's in a hospital in a coma. As the Doctor explains, a coma patient fulfills a multi-form's requirement for a living, but dormant, mind. The Doctor confronts Prisoner Zero as an Atraxi spaceship flies close to the surface of the planet. He reveals, "They're scanning for non-terrestrial technology, and nothing says non-terrestrial like the sonic screwdriver!"

He then proceeds to activate his screwdriver at full power, causing havoc all around him. Lamps breaks, car alarms sound, an old woman's mobility scooter goes flying by, a fire engine drives off without occupants, and a telephone box blows up. "I think someone's going to notice, don't you?" However, the sonic is damaged and the strain of the task causes it to burn out completely.

Prisoner Zero escapes into a sewer as the Atraxi depart, making the Doctor rage at the incompetence of these alien jailers. Rory quickly informs the Doctor where Prizoner Zero went as Amy wonders about it living in her house for 12 years. The Doctor explains that "multi-forms can live for millennia, twelve years is a pit-stop". The Doctor is left to ponder how he can draw Prizoner Zero out into the open; he quickly comes up with an idea, instructing Amy and Rory to clear out the coma ward at the hospital. While Rory is still having trouble believing that the Doctor exists, Amy forces him to comply.

Meanwhile at the hospital, Dr Ramsden is checking on a convulsing coma patient, wondering if he is aware. Prisoner Zero materialises through the vent above and bares its fangs, preparing to strike...

The Doctor returns to Jeff's home, and uses his laptop to break in on a conference call between some of the most advanced scientific minds in the world; he proves his intellect by producing multiple scientific theories and a joke. He uses Rory's phone to write a "slightly intelligent" virus that will turn every digital display in the world to "zero" at the same time. He uploads this virus to the web via the laptop, and encourages them to spread it across the world using every web program possible. He also gives Patrick Moore's number to Mrs Angelo, and advises Jeff to erase his internet history as he has apparently been visiting some sites of questionable taste.

The Doctor commandeers a fire engine to the hospital, communicating with Amy (stuck outside the coma ward due to Prisoner Zero's attack) and instructing her to use her policewoman uniform to get past hospital security. Amy and Rory find the coma ward a mess. They come across a mother and her two daughters, who claim to have survived Prisoner Zero's attack on the ward by hiding in the bathroom. Amy tells the Doctor that Prisoner Zero has beaten them back; he encourages them to get out of the hospital. However, one of the daughters is now talking in her mother's voice — it's Prisoner Zero again. Admitting it has trouble with multiple mouths and baring razor-sharp teeth, the alien chases Amy and Rory back into the coma ward.

The Doctor arrives in the nick of time, texting "Duck!" to Amy and ramming the truck's ladder into the window. He climbs in, asking Prisoner Zero to surrender and remove its disguise. Prisoner Zero refuses, knowing the Atraxi would kill it this time anyway, and wants the entire Earth to die in flames with it. The Doctor enjoys a victory speech as the virus takes hold of the clock on the wall and changes the counter to zero; this occurs all across the world as a means of getting the Atraxi's attention. The Atraxi trace the virus back to Rory's phone, which holds pictures of all of Prisoner Zero's known human forms. The Doctor immediately uploads the photos to them. The Doctor gloats that he did all of it without the help of his TARDIS and sonic screwdriver, and with only two minutes to spare — "Who da man?" The Doctor's self-congratulatory slang gets a series of blank stares and the flustered Doctor mumbles, "Oh, it's, I'm never saying that again, fine!"

However, Prisoner Zero surprises the Doctor by utilising a link it had formed with Amy over the twelve years it had spent living in her house; forcing her into a coma, it takes a new form unknown to the Atraxi from Rory's pictures — that of the Doctor. The Doctor doesn't recognise himself, but, once told, he asks Prisoner Zero why it's mimicking him when it's linked to Amy. A young Amelia comes out from behind the faux Doctor; it's mimicking both of them. The Doctor realises that Amy is dreaming about him, and her dream is enabling Prisoner Zero to take on his form. The Doctor uses his powers of telepathy to encourage the unconscious Amy to instead dream of Prisoner Zero's true form, thereby forcing it to change back. The Atraxi catch it in a paralyzing light and teleport it away. Before departing, Prisoner Zero snarls, "Silence will fall."

With the threat ended, Amy awakes, but the Doctor calls the Atraxi back — they have breached the rules of the Shadow Proclamation by threatening to incinerate a Level 5 planet. Tired of wearing the ragged remains of his previous incarnation's outfit, the Doctor decides to change his clothes in the hospital locker room. Despite Rory's protests, the Doctor steals the clothes, and Amy watches the naked Doctor change into his new look.

Greeting the Atraxi waiting for him on the roof, the Doctor tells them that Earth has not violated any of their laws, and is therefore not a threat to them. He then asks if the Earth is protected, and answers his own question: "You're not the first lot to have come here. Oh, there have been so many. And what you've got to ask is, 'What happened to them?'" The Atraxi display holograms of previous aliens that came to Earth and then of the Doctor's previous incarnations. At that, the Doctor coolly says, "Hello, I'm the Doctor. Basically... run." The Atraxi take the hint and flee in terror.

As the Doctor observes their departure, he realises that the TARDIS key is glowing; the TARDIS has recovered and awaits him. He dashes off to see the new design, being awestruck by his new console room. He decides to take it on a quick hop to the Moon to run in the replacement engines. Amy returns with Rory to her garden just in time to see the TARDIS dematerialising; she is devastated, believing that the Doctor has left her again.

Amy dreams of her younger self awaiting the Doctor's return in her garden, but wakes up at the sound of the TARDIS rematerialising outside. Racing into the garden in her nightie, she is shocked the Doctor has come back again. Even more shocking is that he kept the clothes he stole, including the bow-tie — "Bow-ties are cool." She then angrily informs him that all of the events surrounding Prisoner Zero and the Atraxi happened two years ago; thus, it has been fourteen years since fish fingers and custard, fourteen years since he first promised her a trip. Calling her "the girl who waited", the Doctor muses that she's waited long enough and asks her to join him as a companion.

Amy refuses the Doctor's offer, but changes her mind when the Doctor snaps his fingers, opening the doors of the TARDIS. He gestures inside, and she enters. Amy tells the Doctor that she had come to see him as a madman with a box after all these years, now thinking she was wrong. However, the Doctor tells her that, when travelling with him, there is one very important thing to remember: "I am definitely a madman with a box." Amy then makes the Doctor promise to bring her back to Leadworth by the next morning for "stuff", and they fly off into the Vortex — leaving behind the wedding dress that hangs on Amy's closet door.

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 17 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 already 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 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 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.
 * Caitlin Blackwood (young Amy) and Karen Gillan are real-life cousins, and Gillan convinced series producers to cast Blackwood in the role; amazingly, they hadn't actually met before Doctor Who.
 * Prisoner Zero states that "the Pandorica will open", and repeats, "Silence will fall", both phrases that will be heard for the rest of Series 5.
 * To write the virus, the Doctor uses Rory's BlackBerry Storm (confirmed by Engadget-4/04/10).
 * Lots of speculation began concerning Rory Williams' 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 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.
 * The BBC America broadcast, which was heavily edited down to fit in a 60-minute slot with commercial breaks, left out Prisoner Zero's important "Silence will fall" line, which may have confused some viewers because The Impossible Astronaut uses a flashback to that scene.
 * 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%.
 * The TARDIS control room from the Ninth and Tenth Doctor's era was restored and left standing for eighteen months after it was used in this episode at the request of writer Neil Gaiman. The set was used for the SJA episode The Wedding of Sarah Jane Smith (which involved the Tenth Doctor) and finally for Gaiman's story The Doctor's Wife (which is partially set in this version, which the TARDIS has archived). Production staff had to make up excuses in response to questions as to why the set was left standing. It has since been removed.
 * Music from the Tenth Doctor era (e.g. Midnight, Corridors and Fire Escapes, The World Waits) appears numerous times in this episode.
 * This story contains minor references to previous episodes written by Steven Moffat. Libraries are mentioned on numerous occasions, a possible reference to the two-parter TV: 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 of The Girl in the Fireplace. Similarly, River Song also meets the Doctor at different points in his life — often in the wrong order. The Doctor also says 'Wibbly-Wobbly, Timey-Wimey', as he did in TV: Blink and TV: Time Crash. The Doctor opens the TARDIS by snapping his fingers as he did in TV: 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.
 * It is implied that, at the end of TV: The Angels Take Manhattan, the Doctor visits young Amelia the day after she waits all night for him, at the suggestion of the note the older Amy left for him; he tells her stories of the adventures they will have some day, but that she will have to wait a long time for him to return. According to Steven Moffat, it was this meeting she was dreaming about at the end of this episode, when the Doctor comes back the night before her wedding.
 * This was the first televised Doctor Who story to feature two different versions of the TARDIS control room (the next would be TV: The Doctor's Wife).

Production errors

 * In the opening scene, there are several errors.
 * 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.
 * When the Doctor is talking to young Amelia in her front yard, the background ambient of the "retro" TARDIS interior theme is heard, but the TARDIS still has the old coral theme, which has a different ambient "hum". (However, these sounds could just be "background" sound effects that aren't present in-universe, as at some points they seem to "punctuate" the Doctor's lines almost perfectly.)
 * When the Doctor is eating yoghurt in Amelia's kitchen he gets a smear of it on his chin. However, when the shot goes back to him, the smear is gone.
 * 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 scenes where Amelia first meets the Doctor and those taking place in the kitchen, the Doctor's hair style changes several times, sometimes changing from messy to sleek and then back or vice versa between takes.
 * 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.
 * 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, juggles 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.
 * 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.
 * During the Doctor's conversation with the Atraxi, Rory is standing behind him holding a selection of jackets. As the Atraxi are reviewing the various incarnations of the Doctor, one of the jackets (a dark reddish brown jacket) can be seen on the ground to Rory's left. When the Doctor says the line, "Hello, I'm the Doctor", the coat is still on the ground, but the scene immediately cuts to a closeup with Rory still holding the jacket in his arms.
 * When Amy enters the TARDIS, the rear-bottom panel can just be seen, destroying the illusion of the TARDIS not actually being "bigger on the inside"
 * During the final scene, when the Doctor appears to switch off the monitor, it cuts from a close up of the monitor to a wider angled shot of the Doctor standing at the monitor for a single frame, but then cuts for a single from back to the monitor before going back to the shot of the Doctor.
 * In the kitchen scene, after the Doctor has taken a bite out of the apple and has spat it out, he puts the bitten fruit back into the fruit bowl that Amelia is holding and it can be seen in the bowl when Amelia is running to the refrigerator to get him yoghurt. When she returns with the yoghurt, the bitten apple is lying beside the bowl on the table. In the same scene it can be noted that the clock doesn't change time - it remains at around 32 minutes past 9.
 * When the Atraxi are showing images of the aliens and other creatures that have appeared on the planet, they show a clip of Cybermen breaking through a window, yet that scene took place on Pete's World. Additionally, Ood are shown, despite never have been seen on Earth at this point, as are Hath, who never appeared on Earth.
 * When the Doctor first addresses the Atraxi on the hospital rooftop during the wide shot of both the Doctor and the Atraxi, a bi-directional loop is used to extend the duration of the shot. This is evident when looking at the way the Doctor is moving.
 * As the Atraxi is about to flee the rooftop, when seen from behind the Doctor, its crystalline-snowflake "ship" begins spinning clockwise (when viewed from below), but in the next scene (from the side) it is spinning anticlockwise (when viewed from below) as it actually makes its retreat.

Continuity

 * The majority of this episode takes place in 2008, with the final scene set on 25 June, 2010. Amy is twenty-one at this time (established in Flesh and Stone).
 * This story continues the events seen at the end of TV: The End of Time with the TARDIS crashing towards Earth.
 * Perception filters have previously been mentioned/seen in reference to the TARDIS keys (TV: The Sound of Drums) and the Torchwood Three lift. (TV: Everything Changes)
 * The Doctor uses the phrase, "Wibbly-Wobbly, Timey-Wimey", first used by the Tenth Doctor in TV: Blink and again by both the Tenth and Fifth Doctors in TV: Time Crash.
 * The Doctor opens the TARDIS by clicking his fingers as he first did in TV: 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 appearing in the projected image included the Cybus Cybermen, (TV: Rise of the Cybermen) the Daleks, (TV: Doomsday) a Pyrovile, (TV: The Fires of Pompeii) the Empress of the Racnoss, (TV: The Runaway Bride) the Ood, (TV: Planet of the Ood) the Hath, (TV: The Doctor's Daughter) the Sontarans, (TV: The Time Warrior) the Sea Devils, (TV: The Sea Devils) the Sycorax, (TV: The Christmas Invasion) a Reaper, (TV: Father's Day) and a Vashta Nerada's victim. (TV: Silence in the Library)
 * The Doctor states that he got tired of travelling alone; (TV: Planet of the Dead; The Waters of Mars) he claims he'd been giving himself an earache by talking to himself.
 * 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. (TV: Spearhead from Space; Doctor Who)
 * Following a regeneration, the Doctor expels golden energy from his mouth. (TV: The Christmas Invasion)
 * The Doctor's sonic screwdriver was previously destroyed. (TV: Smith and Jones, TV: The Visitation)
 * The Doctor intending to return in five minutes and accidentally taking twelve years is similar to the first time he takes Rose home in TV: Aliens of London; however instead of taking twelve hours, it was twelve months.
 * When the Atraxi note that the Doctor is not from Earth, he responds with, "No, but I've put a lot of work into it." (TV: The War Machines, The Web of Fear, Spearhead from Space, et. al.)
 * 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 (in fact, he calls the Atraxi back to do so).
 * The TARDIS' doors open outwards for the first time since Episode 1 of TV: The Ice Warriors.
 * The Doctor is knocked unconscious by Amy's cricket bat. In the novelisation for TV: The Power of the Daleks, it was stated that were the Doctor rendered unconscious soon after regeneration the cycle might have started again.
 * The Doctor congratulates Prisoner Zero on "the perfect impersonation of yourself"; gave Adric similar congratulations after he created an illusion of himself to fool Nyssa. (TV: Castrovalva)
 * The TARDIS previously "regenerated" in Mary's Story.
 * The Doctor rejects carrots; his sixth and seventh incarnations disliked carrot juice. (TV: 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 later says in TV: 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 it leaves, just as there was when it materialised in San Francisco on 30 December 1999. (TV: Doctor Who)
 * The Doctor previously used the phrase, "Trust me, I'm the Doctor", when reassuring Leela that blackberries were not poisonous in PROSE: Psi-ence Fiction.

 * The TARDIS scene in which the characters are viewed through the central column as they talk to each other mirrors those seen in the TV Movie.
 * The monitor in the new TARDIS console has a Magpie Electricals logo on it. (TV: The Idiot's Lantern)
 * Like the Eleventh Doctor, the Tenth Doctor also had a distaste for certain foods, particularly pears. (TV: Human Nature/The Family of Blood)
 * Meanwhile in the TARDIS (scene 1) takes place immediately following this episode.
