Factual error: The all important date of 26/06/2010 and it ticks over on Amy's alarm clock right at the end of the episode. However it shows 11.59 AM and flicks over to midday (12.00PM) the next day. The date should've stayed on 25/6 or, as I suspect was the intention, the clock should've read 11.59 PM and then ticked over to 12.00 AM thus changing the date correctly. (00:41:00)
The Vampires of Venice - S5-E6
Factual error: Isabella is a black girl living in 1580 Venice. So how is it that she has perfectly straight hair, when modern hair care products won't be invented for centuries?
Vincent and the Doctor - S5-E10
Factual error: Amy inspires Vincent to paint sunflowers for his iconic Sunflowers painting. The episode takes place in 1890, even though Van Gogh completed Sunflowers two years earlier in 1888. (00:18:25)
Vincent and the Doctor - S5-E10
Factual error: By the time the Doctor and Amy meet him, Vincent van Gogh had already mutilated his ear. He should be missing part of his left earlobe.
Factual error: When the Doctor, Amy and Rory are on the roof and the Doctor says "The question for now is total event collapse means that every star in the universe never happened", the Gherkin can be seen in the background. However, the Gherkin wasn't built until 2003, whereas this episode takes place in 1996. (00:22:40)
The Wedding of River Song - S6-E14
Factual error: During the zoom-out from Earth at the end, the Sun is depicted as far, far too large than it actually appears from Earth. (00:40:03)
The Doctor, the Widow and the Wardrobe - S7-E1
Factual error: Cyril is introduced looking at the Moon with a telescope... in a brightly-lit room through a window with the curtains mostly shut, circumstances in which he's not going to see anything at all. (00:03:56)
Factual error: During the standoff after the Doctor forces Jex over the town's boundary line, Amy manages to make a revolver accidentally fire off twice in a row. Revolvers like that need to be cocked between each firing, which didn't happen the second time. (00:23:54)
The Bells of Saint John - S7-E8
Factual error: Clara determines the location of the enemy's base of operations: floor 65 of The Shard. However, there are multiple issues with this conclusion. Firstly, floor 65 is a residential property, not an office location; offices in The Shard occupy floors 2 through 28. Secondly, the view of 30 St Mary Axe from Miss Kizlet's window puts the office below 180m, the height of the latter building. This would mean the office must be below floor 50. Finally, when the Doctor rides his motorcycle up the side of the building, 30 St Mary Axe is again seen, this time significantly below his location, and on the wrong side of The Shard. Not only then does the office's height change, but also which side of The Shard it is on. (00:36:06 - 00:38:40)
The Bells of Saint John - S7-E8
Factual error: The view from Ms Kizlet's window was taken somewhere in the vicinity of London Wall eg. the Museum of London, not from The Shard.
Factual error: The rank insignia of the Soviet officers is completely inaccurate. The captain wears the epaulets of a captain first rank (captain) and the sleeve insignia of a captain second rank (commander). Lieutenant Stephashin wears the epaulets of a senior lieutenant and the sleeve insignia of a captain third rank (lieutenant-commander). The third officer wears the epaulets of a captain second rank and the sleeve insignia of a captain third rank.
Factual error: The Doctor says that the Earth is six billion years old, which is one and a half billion years over - it's only 4.5 billion years old. (00:21:25)
Factual error: In this episode, it is stated that the Moon's sudden increase in mass caused a devastating global high tide. The amount of the increase in mass is given as 1.3 billion tonnes. But the Moon has a mass of over 70,000,000,000 billion tonnes, or over 50 billion times the supposed increase. Such a negligible increase in mass, less than 0.000000002%, would have almost no effect on Earth's tides, let alone be devastating. (00:20:46)
Factual error: When Clara is watching the Earth through binoculars in order to see whether people left their lights on or off, the planet is rotating at an impossibly high speed. (00:36:15)
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.
Factual error: After PC Forrest is killed by the Boneless, her nervous system is flattened and displayed on the wall, appearing as a mural. However, there are far too many nerves around where her liver would have been and not nearly enough around her brain.
Dark Water - S8-E11
Factual error: When Clara is speaking on the phone to Danny at the start of the episode her phone shows the call waiting screen for an incoming call from him. (00:02:25)
Factual error: The Viking village has tubs of electric eels in the boathouse, which prove instrumental to the plot as the power source of the makeshift electromagnet used to relieve several of the attacking aliens of their helmets. The problem is that the Vikings live somewhere in northern Europe, and this episode takes place in the 800s. Electric eels are native to the Amazon and Orinoco rivers of South America, which at this point in history no one in Europe knew existed.
Factual error: By halfway through the episode, the plot is alternating between following Clara and Jac in London, the Doctor in the fictional Central Asian country of "Turmezistan", and Kate in New Mexico. Despite the three locations being scattered all around the world, only in London is it depicted to be nighttime at any point in the episode. Central Asia and the southwestern USA are both shown to be daytime, despite the two locations being over halfway around the world from each other, and the events all taking place at roughly the same time.
The Pyramid at the End of the World - S10-E8
Factual error: The American officer is called a Colonel but he wears the four star rank patch of a General, and that rank patch is even upside down in some scenes. The stars should have one point upwards.
