The Sound of Drums (2) - S3-E12
Continuity mistake: In the conference room, Saxon (The Master) puts on a gas mask that has an emblem mounted above the hose. After replying to the question, he moves the mask, and the emblem is on the bottom of the mask.
Last of the Time Lords (3) - S3-E13
Continuity mistake: When the Master says that the Doctor sealed the rift at the Medusa Cascade single-handed, in a wide shot, his right hand is resting on the edge of the table he's sitting on. The scene cuts to a close-up, and then back to a wide shot, where the Master's right hand is now in his lap. (00:10:30)
Last of the Time Lords (3) - S3-E13
Deliberate mistake: The Master uses his laser screwdriver to suspend the Doctor's ability to regenerate. While he is in fast motion, in a close-up you can briefly see Lucy's arms in fast motion as well. (00:12:20)
Last of the Time Lords (3) - S3-E13
Continuity mistake: When Martha explains to Tom and Professor Docherty about how the Master could only use the TARDIS to travel between the present day and the end of the universe, and how he must have gone to Utopia, in a wide shot her right hand is resting on the table, but in a shot from above looking down on the captured Toclafane her right arm is by her side. (00:20:15)
Last of the Time Lords (3) - S3-E13
Continuity mistake: When the Master says, "Out you come, little girl. Come and meet your Master," his arms go from lowered to raised between shots. (00:27:20)
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)
Last of the Time Lords (3) - S3-E13
Continuity mistake: When Martha walks up the Valiant's bridge, she passes Captain Jack and her family before stopping just short of the bottom of the stairs. In the next shot, she's still walking as she looks at the Doctor. (00:29:30)
Last of the Time Lords (3) - S3-E13
Factual error: When time is seen rewinding after the destruction of the Paradox Machine, the Earth and Moon are seen rotating and orbiting backwards. The Moon is depicted far closer to Earth than it actually is. (00:37:40)
Last of the Time Lords (3) - S3-E13
Continuity mistake: When the Doctor is cradling the Master's body, in the close-up his right hand is curled up into a fist, but in the following wide shot is wrapped around the Master's shoulder. (00:41:45)
Last of the Time Lords (3) - S3-E13
Continuity mistake: When the Doctor and Martha react to discovering that Jack is the Face of Boe, the position of the Doctor's arms on the railing in front of them changes between shots. (00:45:05)
Factual error: The opening shot of the episode reuses the zoom-in from orbit originally used in "Rose." The North Pole is sunlit, as it would be at the height of summer. "The Runaway Bride" takes place on Christmas Eve, four days after the Northern Hemisphere's Winter Solstice, when the Pole would be facing away from the Sun, in darkness. In fact, this was the second Christmas special in a row to make this mistake, after "The Christmas Invasion." (00:00:05)
Continuity mistake: The episode repeats the closing scene of "Doomsday", when Donna unexpectedly appears in the TARDIS. However, several details are different. One, the console room is more brightly lit than in the previous episode. Two, the shirt belonging to Rose that Donna finds draped over a railing was not present. Three, the Doctor's coat (draped over a ceiling support) has shifted in place, despite not being touched. (00:01:15)
Continuity mistake: When the Doctor sonics the payphone so Donna can call her mother, he's doing it with his right arm, then it cuts to close-up and he's using his left arm. (00:09:00)
Continuity mistake: In the scene when Donna asks the woman if she could borrow £10 because it's Christmas, you can see that Donna is wearing sports shoes instead of her usual white wedding shoes. (00:10:05)
Suggested correction: No, she's wearing the same shoes if you pay attention.
Never mind - she is wearing running shoes for no apparent reason.
Continuity mistake: The cab Donna's in passes a red vehicle on the bridge. A second later, it's nowhere to be seen looking back. (00:12:15)
Visible crew/equipment: As the Doctor tries to get Donna to jump to the TARDIS, as the camera is in a close up on her in the taxi, the yellow camera vehicle is reflected on the cab's paint. (00:12:50)
Continuity mistake: When the Doctor picks up a mug and a pencil to use as props to explain to Donna how she was pulled into the TARDIS, he is initially holding the pencil by the blunt end. The scene cuts to a shot of his face, and suddenly he's holding it by the sharpened end. (00:28:35)
Character mistake: When the Doctor is taking Donna to 4.6 billion BC to watch the formation of the Earth, he says that it is the furthest back the TARDIS has ever been. But in the 5th Doctor episode "Castrovalva", the TARDIS drifted to 13.2 billion BC and the formation of the galaxy. (00:40:35)
Continuity mistake: When the TARDIS arrives back from the formation of the Earth, the Doctor and Donna rush out leaving the TARDIS door open. And yet in the very next shot, the door is closed. (00:44:30)
Continuity mistake: When the Doctor is giving the Racnoss Empress an ultimatum, the position of his hands on the railing in front of him changes between shots. (00:48:00)
