Continuity mistake: When the Doctor is talking to the Amelia voice interface, in a shot of him from behind his position slumped against the railing is different from shots of him from the front. (00:27:37)
Revealing mistake: Mels is shot in the stomach by Hitler, leading to her regeneration. Rory, when checking the wound, says he's going to try and stop the bleeding. However, when she stands up while glowing with regeneration energy, and in every scene afterwards where Mels/River is wearing that dress, there is no bullet hole or bloodstain visible.
Other mistake: When the Doctor gets George's psychic cry for help, he's shown reading the message without opening the wallet containing the psychic paper. This despite the fact that all previous instances of the Doctor receiving psychic messages this way has required him to open the wallet, suggesting that the wallet itself does not display the message. (00:02:02)
Continuity mistake: When Amy and Rory are searching the darkened kitchen, the flashlight Rory holds switches hands between cuts when it starts turning on and off. (00:13:52)
Continuity mistake: When Purcell is sinking into his carpet, just after a shot where he's shown having sunk into the floor up to his waist, we see a shot focusing on his dog where Purcell's legs are visible as he falls forward onto his hands, despite his legs having already been pulled under. (00:23:38)
Continuity mistake: When Alex is hugging George after rescuing him from the peg dolls, George's arms are down in shots facing Alex, but his left arm is up in shots facing him. (00:37:23)
Revealing mistake: When the landlord, Purcell, wakes up on his floor because his pet dog is licking his hand, we see a few pieces of dog food fall from his fingers - should have been a re-shoot, but all credit to the actor, he knows it has happened and is quick to hide them again. (00:38:38)
Continuity mistake: When Rory brings the unconscious Amy inside the TARDIS and puts her on the floor, the Doctor drapes his jacket over her twice. (00:39:44)
Continuity mistake: As Lucy goes down the hall, she opens door 214, then 215. As she comes to the next door on the right, she opens 214 again, rather than it being 216. This is particularly noticeable because the third room she enters is "her" room, containing her greatest fear - and the first room she went into numbered 214 had a completely different fear. (00:00:56)
Continuity mistake: When the Doctor tells Howie that he should continue telling himself the situation is a "CIA thing", he puts his arm around his shoulders twice. (00:11:22)
Continuity mistake: When the Doctor finds Joe's corpse, he walks up to him and puts his hand on his shoulder. In the next shot, facing Joe, the Doctor is suddenly in a completely different position relative to him, behind him as opposed to next to him. (00:15:06)
Continuity mistake: During the Doctor's phone conversation with Rita, the handset of her phone keeps switching between ears. (00:32:30)
Continuity mistake: When the Doctor overhears Alfie crying while stirring something in the kitchen, he has the spoon in his hand in the close-up, but his hand is suddenly empty in the wide shot. (00:23:02)
Continuity mistake: When Craig enters the house and falls back when the cybermat is attacking him, his arms are down by his sides, breaking his fall. As he lands, he's suddenly holding the mouse so it can't bite him. (00:25:51)
Revealing mistake: When the Cybermat gets free after the Doctor tries to hit it with a pot and accidentally gets Craig instead, it is very obviously CGI when it slides along the floor and stops by a piece of furniture. (00:26:34)
The Wedding of River Song - S6-E14
Continuity mistake: During the live chess game, the position of Gantok's hand changes between wide shots and close-ups of the electrified queen piece. (00:06:33)
The Wedding of River Song - S6-E14
Continuity mistake: When the Doctor realises he's picked up a model of the TARDIS in Amy's office, it rotates in his hand between shots, as indicated by the positioning of the sign on the front door. (00:20:55)
The Wedding of River Song - S6-E14
Continuity mistake: When the Doctor compares Amy's inaccurate drawing of Rory to the real deal and laughs, in a shot facing Rory the Doctor is shown lowering the picture, than in the next shot facing the Doctor he still has the picture raised. In addition, his grip on the paper changes from holding the bottom of the page to the side, and it also switches hands. (00:23:33)
The Wedding of River Song - S6-E14
Audio problem: When Amy says the last two words of "Do you know what else he is, Madame Kovarian?", her mouth doesn't move. (00:34:07)

Continuity mistake: When the Doctor and River are wrapping his bowtie around their hands in a handfasting, the length of the cloth changes between the close-up and the wide shot. (00:37:40)
