Revealing mistake: After the Doctor deactivates the signal hiding the Dalek fleet, when the camera zooms out to show the ships, the background image of the Horsehead and Flame Nebulae is cut off a bit below where the Dalek Emperor's flagship is shown, revealing the end of the picture they used for a background. (00:39:00)
The Parting of the Ways (2) - S1-E13
Continuity mistake: At the beginning of the scene where Rose, Jackie and Mickey are in the restaurant, in the wide shot, Rose moves her left hand to the side of her head, while looking down with her head facing towards the other side of the table, which her elbow is resting on. In a close-up immediately afterwards, she's looking out the window with her hand to her face and her elbow resting on the windowsill. (00:18:50)
Revealing mistake: When the Gamestation's transmissions are cut off by solar flares, there is a close-up of a screen going over to static. In the upper right corner, a box with "Play" written in it is visible, revealing the image on the screen as a video. (00:34:50)
Other mistake: After Jack uses Davitch's information to complete the Controller's coordinates, the Doctor uses a remote to project a holographic, transparent screen of the location in question. The image shows Orion's Horsehead and Flame Nebulae. In a shot immediately afterwards, looking through the holo-screen back at the Doctor and company as he explains what's going on, the image of the nebulae is not mirror-reversed as it should be, but is the same orientation as in the previous shot. The kicker is that the image of the nebulae has been altered, as well: it's already been mirror-reversed - in the actual sky, the Flame is left of the Horsehead. (00:38:40)
The Doctor Dances (2) - S1-E10
Continuity mistake: When the Doctor is looking at Rose's hands, turning them over repeatedly, while she's describing how she was hanging from a barrage balloon, there's one moment where her hands are turned palm-up in a shot facing her, but back-up in a shot facing him. (00:18:25)
Continuity mistake: When the Doctor meets Nancy, when she warns him not to answer the TARDIS' ringing (fake) door phone, in a shot facing her he's holding his jacket away from his chest, but in the next shot facing him that hand is empty. (00:06:55)
Continuity mistake: When Jack is scanning Rose onboard his spaceship during their conversation, he leans against a metal railing in front of The Pilot's seat twice, in two successive shots. (00:20:40)
Continuity mistake: During the Doctor and Nancy's conversation at her hideout, in shots facing her there is a bright circle of light cast on the wall to her left, which her shadow partially overlaps. In shots facing the Doctor where both him and Nancy are visible, the circle is gone, and Nancy's hideout is noticeably more dimly lit. (00:23:15)
Father's Day - S1-E8
Continuity mistake: When Rose checks her messages while riding in Pete's car and hears the very first phone call instead, the positions of her fingers change between the wider shot and the close-up. (00:13:30)
Continuity mistake: When the Doctor is restrained by two of the Editor's corpse minions, and the Editor demands to know who he is, the hand of the one holding the Doctor's right arm moves between his chest and shoulder several times. (00:30:50)
Continuity mistake: When Rose and Adam are in his workshop talking about aliens, during the exchange where she asks him about people who claim they've been in spaceships and he responds that he thinks they're nutters, Rose is poking around with her right hand at a storage shelf on the wall before moving her hand to a pile of boxes stacked on a table. When the scene cuts to a close-up of her, her hand has jumped back to the shelf. (00:12:40)
Continuity mistake: When Jackie is reporting the Doctor to the alien helpline, her grip on the cordless phone changes between shots. (00:29:55)
Continuity mistake: When Joseph Green (really Jacrassa Fel-Fotch Passameer-Day Slitheen) picks up the skin of Oliver Charles from the Cabinet table, he picks it up with his left hand in the first shot but is holding it with his right hand in the next. (00:32:30)
Continuity mistake: When Jackie is yelling at the Doctor about Rose's yearlong disappearance, in a shot facing her she turns her head to her right, then in a shot facing the Doctor she does it again. (00:04:00)
Continuity mistake: When the Doctor and Rose are talking on the roof, just before the spaceship appears, Rose's hair is blowing in the wind in shots facing the Doctor, but mostly still in shots facing her. (00:05:10)
Continuity mistake: During Harriet Jones' introduction, her grip on her ID card changes between shots. (00:12:25)
Continuity mistake: When the coroner is interrupted by a banging coming from the freezer while trying to do paperwork, she's shown turning around and standing up twice, in a close-up and the long shot. (00:19:20)
Continuity mistake: Early on, when Rose is talking to the Doctor about how amazing it is that they can visit days that only happened once, her hair moves from tucked behind her ear to covering it, then back to its first position. (00:05:00)
Continuity mistake: When Rose pulls out her phone and checks for a signal, she's holding it with two hands in the shots facing her, but only with one hand in the shots from behind her. (00:17:50)
Continuity mistake: When the Doctor is putting a new battery in Rose's phone, which hand he's holding it with keeps changing between shots. (00:18:00)
