Factual error: At the end when Skeksis enters the crystal chamber, in the overhead shot you can see 22 arcane symbols around the crystal when there should only be 18, one for each exiled skeksis. (00:45:53)
Episode #1.1 - S1-E1
Factual error: There is a view of the night sky in southern Africa. However, both the Big and Little Dippers (along with Polaris) are visible. In general, these constellations are not visible in the southern hemisphere, and where they are (North of 1° South latitude) they are very close to the horizon. The Big Dipper (Ursa Major) is to the left of the screen and Polaris (part of the Little Dipper = Ursa Minor) in near the top-center. This occurs shortly after the lion cub scene. (00:44:00)
Pride Parade - S5-E3
Factual error: Nandor manages to fly up to space, then loses control and falls back to earth in a fireball as he reenters the atmosphere. But objects reentering the atmosphere only get hot because they're generally travelling at immense speeds, 7-12 kilometers per second. Nandor just floated straight up, then falls straight back down. When Felix Baumgartner parachuted from the edge of space his maximum speed was about 1,300 km/h, and he didn't catch fire.
Factual error: The group finds an underground sea and there is a flock of pterosaurs flying overhead. The professor identifies the pterosaurs as the missing link between pterodactyls and archaeopteryx. This is not true as archaeopteryx (and other birds) did not descend from pterosaurs but from a branch of theropod dinosaurs.
Factual error: Constantine's driving licence is shown - it's a UK licence, but no. 7 where his signature should be is blank, and no. 8 where his full address should be simply says "England, United Kingdom." Both are printed onto the licence when it's issued - without that info it would never be issued in the first place. And it's not a fake, because why would he have a fake licence with his real information on it? It's just an incomplete prop.
Factual error: Many elements of Marlott's trial and execution are incorrect. The judge sits with two assessors (a European practice, not a British one). He is addressed as 'Your Honour' instead of the correct 'My Lord'. He instructs the jury to find Marlott guilty and then goes straight to sentencing, which would never happen; a judge can instruct a jury to acquit, but not convict. He puts the black cap on himself, instead of an attendant doing it. The form of words for the death sentence is incorrect. The chaplain (who appears to be Catholic, not Anglican) gives a speech at the scaffold.
Factual error: In the last minutes, the show looks forward to future challenges, in effect a preview of the never-made 3rd series. The oracle says they must find "the golden fleece, woven long ago by the Stygian witches." But the golden fleece, or indeed any fleece, is not a woven fabric. (Today's fleece is a modern invention).
Factual error: Somewhere in season one Mary refers to Germany. But since this was set in the 16th century it would've been Prussia.
Factual error: As Ren enters Renautas and meets Emily, the word "Welcome" keeps scrolling in various languages on the screens in the background. Although hardly seen, the Hebrew is wrong, as it is reversed (text from left-to-right, as opposed to right-to-left).
Factual error: Helmuth von Moltke is addressed and referred to several times as Field Marshal. He wasn't promoted to that rank until 1871. He was a lieutenant-general during the Second Schleswig War in 1864.
Factual error: The episode has Mona Lisa and Teddy traveling to Yakima, Washington, showing green, tree covered hills. Yakima is in the middle of the Washington State desert, so the topography would be mostly flat, desert terrain, with yellow and brown colors.
Suggested correction: Don't think you have ever been to Yakima because Yakima is surrounded by hills and the only part that is flat is in the valley and Terrace Heights. I live in Yakima, and the map they showed of E Yakima Ave and Chestnut Ave and filming is wrong, though, because that area of the map is mostly neighborhoods, small businesses, and mini-marts. No trailer parks with a bridge nearby that has hills behind it in that area.
Factual error: Thomas holds the Gendarmerie rank of Capitaine (by which he is frequently addressed by his subordinates), and thus should wear three horizontal silver bars on his epaulettes. However, in the only scene where his rank is displayed he instead wears the two chevrons of an ordinary gendarme.
Factual error: When Mr Gore destroys the television set, it is obviously a prop, as when he breaks the screen there is no noise, in reality there would be a loud bang as there is a vacuum behind a TV screen of that era.
Factual error: In "What Happened to Frederick", Kathryn learns about David's affair and confronts Mary Margaret at school (after taking her anger out on Regina), where students and teachers are milling about. Later, she apologizes to Regina for "what happened yesterday", whereas Emma, earlier that day, seeks out Henry at school. Kathryn leaves Storybrooke the same day, and mysteriously disappears. According to Kathryn's phone records in this episode, she disappeared on a Sunday. However, the day she left, and the day before, was a school day. In the U.S., school classes are not in session during weekends. (00:38:25)
Factual error: Squirrels are seen woken from hibernation along with other animals, but squirrels don't hibernate.
Factual error: During the flash back of 1912, one of the characters pulls an American note out for Damon, and it had the date 2016 or 2010 on. (00:13:00)
Suggested correction: That's not the date. The blue number is basically the serial number, not the date. The series date would be in too fine of print to see in the shot of the bill.
Factual error: When His Divine Shadow lays on the table to have his brain removed, the machine cuts his skull open and simply reaches in with a three pronged hand and tugs on the brain pulling it out. It would not have worked this way... The brain is about the same consistency as gravy and the prongs on the hand/claw putting pressure on it to pull would have caused them to sink into the brain's tissue destroying it. Also it pulls the brain out without cutting or separating it from the spinal column and merely just pulls it out from the top. This would have caused his brain to be torn into pieces as it was tried to be pulled off the spinal column, not come out perfectly in one piece as shown. (01:09:00)
Los Moscos - S2-E1
Factual error: Outside the church headquarters where Norman has his stroke is a board saying 'United Methodist Church'. The UMC didn't come into existence until 1968. It was the Methodist Episcopal Church in the 1930s.
Song of the Younger World - S2-E20
Factual error: The 19th Century reformatory has modern electric light bulbs hanging from the corridor ceilings. (00:21:10)
Factual error: Even though the show is called "Samurai Jack", Jack isn't really a samurai. The correct title for him would be a Ronin as a Ronin loses their master if their master dies or loses favor with their master and also has no home anywhere. Jack has these attributes. He has no master and no home.
Suggested correction: Nor is his name really Jack. "Jack", and thus "Samurai Jack", is just an alias that the prince takes. It's not meant to be his title or rank. Just like Cowboy Jack wasn't actually a cowboy.
