Corrected entry: When the Doctor and Martha are in their bedroom, there are many candles lit. Later, when Martha blows out one candle, the whole room goes black.
Factual error: When Rose is locked in the room and the bodies come toward her, you can see a modern-day electric light-switch to the side of the door she's trying to get through. When the Doctor hears her screaming for help and runs for her, you can see a central heating radiator. In fact, the undertaker's house has at least two radiators in different hallways. Both are wildly anachronistic for the time period. (00:16:30 - 00:17:08)
Suggested correction: While the light switch is ahead of its time, the heating radiator was invented by Franz San Galli in 1855 and was immediately popular. It's possible that by 1869, when the episode takes place, that Mr. Sneed would have one.
Corrected entry: The clock on the wall of Rosa Parks' workplace is an IKEA Bravur model, which didn't exist in 1955.
Correction: There are other clocks of a very similar design, which have been available for years.
Corrected entry: The Doctor meets the future Ada Lovelace in the year 1834, where her maiden name is given as Ada "Gordon." She was actually born Ada Byron, inheriting her last name from her father, the famous author Lord Byron.
Correction: Ada Lovelace was born "Ada Gordon."
Factual error: The upper peninsula of Michigan is missing on the map of the US shown on Van Statten's monitor.
Suggested correction: In that era of Doctor Who the Earth was being invaded by aliens on a regular basis. Since the story is set in the 'future' year of 2012, anything may have happened to wipe that part of Michigan off the map.
I'm from Michigan and when I noticed the UP missing, I jokingly said to a friend "looks like Canada stole that finally"
Character mistake: The question to unlock one of the doors asks for the next number in the sequence 313, 331, 367. The Doctor gives the answer as 379 with a convoluted (albeit correct) explanation of happy primes, but there are much simpler solutions. The difference between the first and second numbers is 18 and the difference between the second and third is 36 (which is 2 x 18), suggesting that the difference between the third number and the next could be either 54 (= 3 x 18), giving 421 as the next number, or 72 (= 2 x 36), giving 439. It's likely that the Doctor would see that the answer is ambiguous, and yet he confidently states that the most complicated answer is correct. (00:08:45 - 00:09:15)
Suggested correction: If you know what a happy prime is, like the Doctor does, it might be simpler than your idea because you gave 2 options - 421 and 439. The idea of a pattern is there should be only one answer that fits, which would be the case if they're all happy primes.
The Day of the Doctor - S7-E16
Continuity mistake: In this episode, I. M. Foreman's scrapyard is at the end of the alley next to Coal Hill School. In "An Unearthly Child", the scrapyard was far enough away from the school that Barbara and Ian take Ian's car to get there. Barbara also describes it to Ian as "there's a big wall on one side, houses on the other." If it was right next to the school, she would have mentioned "that scrapyard next to the school." (00:00:15)
Suggested correction: The evidence to this is merely a sign directing people to the scrapyard. This does not indicate whether or not the scrapyard in question is actually at the end of that road.
That still seems to be a point to bring up. Or better yet, "Her address is the same as the scrapyard on that sign outside the school."
The Day of the Doctor - S7-E16
Deliberate mistake: Looking closely at the floor of Eleven's console room reveals that the part of the floor around the console facing the door has been discreetly raised up, which it isn't in any other appearance of this console room, so that Clara can ride her motorcyle inside it without going down two steps. This wasn't in any previous episode and is gone in the next one.
Suggested correction: The Tardis has constantly shown it can change its internal structure to fit its needs or desires.
Revealing mistake: In the opening scene the Doctor and Donna are speaking over the phone. The purple phone Donna is holding shows the slot where a cable should be plugged in, but there is none. (00:00:25)
Suggested correction: This shouldn't be considered a mistake. While it's true in real life this phone has a slot for a cable, they're on an alien planet and this is unknown technology. In-universe there's no way of knowing what that slot is for, and there's no reason to think the phone needs to be plugged into anything.
Rise of the Cybermen (1) - S2-E8
Other mistake: Alternate Jackie is said to be turning 40. According to a newspaper Mickey finds early in the episode, the parallel universe is in the same year as the main universe. When Jackie's age (she claims to be only turning 39) is announced at the party, Rose does not in any way react as though that's different from the age of main-universe Jackie. The problem is that, given that Rose was 19 when she met the Doctor, and it has been, for main Jackie and Mickey, likely at least two years since the events of "Rose" (remember Rose's one-year accidental disappearance), this means Jackie would have had to have gotten married, and had Rose, before she turned twenty, and been a widow by the time she was twenty. Given that Jackie is from the UK, a first-world country, and that she seems to be in her twenties in "Father's Day", this is highly unlikely.
Suggested correction: "Highly unlikely" is not impossible, there are many cases of this sort of thing happening even in the age of contraceptives. The episode is also set during the 80's, so it's possible that Pete and Jackie were misinformed. There are other TV shows such as Raising Hope or Bump that use this as a major plot point - hell, the very next episode after Fathers Day features an approximately 12-year-old mother in the form of Nancy, the 17-year old mother of antagonist Jamie.
Factual error: Near the end of the episode, the full moon is shown in the daytime sky, well above the horizon. This is impossible, as any celestial body lit by the Sun has its full phase only when it is directly opposite the Sun; thus, a full Moon rises at sunset and sits high in the sky only during the night. For the Moon to be in the sky during the day as shown, it would have to be visibly of a phase other than full.
Suggested correction: The moon is not actually completely full. It's in a gibbous phase (opposite of a crescent), which can indeed be seen in the daytime.
The Bells of Saint John - S7-E8
Corrected entry: When the Doctor and Clara are on the motorbike, Clara says her first line without moving her lips.
Correction: Rewatching the episode, not actually the case.
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.
Continuity mistake: When Donna starts fiddling with the Adipose necklace she stole, this causes an Adipose to be created out of Stacey's fat cells. When this begins, Stacey is in the upstairs bathroom applying lip gloss, and she's holding the applicator wand when her stomach begins to move. When she pulls up her shirt to look at her distending stomach in the mirror, the lip gloss wand is gone. (00:07:15)
Suggested correction: Actually, it looks like she finished putting on lip gloss and put the lid with the applicator back on just before she starts feeling queasy from the impending Adipose birth.
Correction: When Martha blows the single candle's flame out and it goes black, it's not their whole room going black, it's the screen that does a "cut to black" to effectively terminate the shot. This instantaneous dramatic transition punctuates Martha's extreme annoyance with the Doctor.
