Continuity mistake: At the beginning, Missy is using a knife to sharpen a stick to a point. Later in the scene, when she says to Clara that if they go rescue the Doctor, everything the Daleks can throw at them is between them and him, she lists only the stick among their assets. The knife is never seen or mentioned again after Missy was done with it. (00:04:18)
Continuity mistake: After the Doctor is knocked unconscious, Clara uses the psychic circuitry to pilot the TARDIS to what turns out to be a moment in the Doctor's past, in the barn first seen in "The Day of the Doctor." The loft in the barn where the young First Doctor is sleeping in bed, however, was not present in the previous episode.
Suggested correction: These events take place thousands of years apart. Buildings (especially wooden ones) are likely to change in that time.
The barn appears three times, in "The Day of the Doctor", "Listen" and "Hell Bent." Its appearance in "The Day of the Doctor" is chronologically in-between its appearances in "Listen" and "Hell Bent." Both of the two latter episodes have the loft, but "The Day of the Doctor" doesn't. That's the mistake here.
Daleks in Manhattan (1) - S3-E4
Continuity mistake: When Diagoras enters the Daleks' lab, he is shown pulling on his right glove twice. (00:18:55)
Continuity mistake: When little Amy looks out the window to see what makes the noise, you can see the TARDIS through her window (it's a little blurry) but when you look through the window properly, it isn't there.
Continuity mistake: During the Doctor's class he draws lines on the chalkboard, which continually change shape between shots. (00:04:05 - 00:05:10)
Knock Knock - S10-E5
Continuity mistake: When Bill walks out of the TARDIS, her teddy bear is lying in the box she's carrying with its head to Bill's right. In the next shot from behind Bill as she sets the box down on the ground, the teddy is suddenly lying the opposite way. (00:06:45)
Continuity mistake: The Doctor's hairstyle alternates from parted over the left side to a right side part and back while standing by the Pandorica. (00:27:40)
Continuity mistake: Throughout the episode, the collar of the Doctor's shirt frequently tucks in and out of his coat from shot to shot. Especially noticeable in the scenes where they are looking for and subsequently fix the Dalek's radiation leak.
Continuity mistake: In the scene where Rory pushes a Dalek backwards it has ear lights but in the next shot it doesn't.
Suggested correction: The close-up shot of the Dalek just as Rory pushes it is positioned such that the ear lights, and the place where they're mounted, isn't visible anyway.
The Day of the Doctor - S7-E16
Continuity mistake: When the War Doctor kisses Clara goodbye, his tea cup rests on top of the saucer, but when he steps into his TARDIS the cup sits on the bench, beside the saucer.
Continuity mistake: After the Master changes all humans into copies of himself and Wilf says, "What have you done, you monster!?", it goes to all the different Masters in the room saying, "Are you talking to me?" The Abigail Naismith-Master is shorter than the Joshua Naismith-Master. In another shot they are the same height. The Abigail Naismith-Master is wearing very high heels and should be taller than the other Masters. (00:56:00 - 00:56:50)
Continuity mistake: When Amy is trying not to forget Rory, the memory of him getting shot does not show the laser blast striking him. (00:41:44)
Last of the Time Lords (3) - S3-E13
Continuity mistake: Just after the Master destroys the gun in four parts, there is a shot from exactly the same angle and the bag it was in has disappeared. There is then a shot from the other direction and the wreckage is still there. (00:28:35)
Continuity mistake: When Yvonne is taking the Doctor and Jackie to the Sphere Room, there is a sign opposite the door that has the words "Torchwood Institute". In the next shot where you can see the corridor from inside the Sphere Chamber, the sign has disappeared. It reappears again when Rose is going into the Sphere Chamber, but this time it has directions to the Reception, Canteen and Lever Room as well as "Torchwood Institute". It also disappears again when you see the corridor from inside the Chamber. (00:23:30 - 00:31:45)
Continuity mistake: While hiding behind the mini-skips, Rose and Pete hold hands. After a cut to close up, they hold hands again. (00:08:55)
Continuity mistake: In the scene toward the end where the Doctor is shot by the Dalek, when the camera is shooting from Rose's point of view, the Doctor is gasping and struggling for breath. However when the camera shows the Doctor from behind, he's lying completely still in Rose's arms. The camera cuts back to Rose's POV and he's struggling again, with no time in between for the change in his movements. (00:43:35)
Continuity mistake: As the Doctor, Captain Jack and Lynda with a Y have been captured, the Doctor turns his head to the right, then after it cuts it shows him turning his head again and saying "Let's do it." (00:32:05)
The Sound of Drums (2) - S3-E12
Continuity mistake: When gassing the cabinet members, the Master puts on a gas mask. The Valiant logo is above the tube, and upside down. In the next shot, it is below the tube, and the right way up. (00:04:50)
Continuity mistake: When Ursula is filming Elton outside his old house, the digital camera produces a distorted picture and has four white lines in the corners. But, after Elton's flashback, Ursula is still filming but the picture is straight and the lines are gone. (00:04:40)
Continuity mistake: Throughout series 5 and series 6, The Doctor's hair style keeps changing sides.
