Factual error: Squirrels are seen woken from hibernation along with other animals, but squirrels don't hibernate.
The Frankenstein Murders - S1-E5
Factual error: When Mary looks at the newspaper, it says "Tuesday, March 31, 1827." But that was a Saturday.
Factual error: When Alina stands outside of the door to the banquet hall, waiting to demonstrate her power to the king and queen, there is a modern electronic occupancy sensor on the wall behind her.
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: Despite taking place in Massachusetts and many of the cars having Massachusetts license plates, none of the vehicles has the required annual inspection sticker on the lower part of the passenger side of the windshield.
Factual error: A man enters a bank and begins firing his Glock 9mm pistol. A few of the men he shoots, jump up in the air after the rounds impact their bodies. Bullets hitting a body will never make it jump, or fly in the air. (00:00:01 - 00:01:46)
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.
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)
Yomigaere! Eiyuu Densetsu - S1-E1
Factual error: When Seiya cuts off Cassios' ear, it pulses on the floor like it's a beating heart. There can hardly be a muscle twitch in a severed ear. (00:05:30)
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: The map of the western United States shown during the weather report at the start of the episode shows some states drawn incorrectly. Idaho's entire western border is a straight line, whereas in real life, Oregon has a horn-shaped indentation on its northeastern border that it shares with Idaho. Idaho also looks like a crude staircase, with the southwestern border of Montana going down to central Wyoming, whereas that area in real life is around the northwestern part of Wyoming.
Welcome to Hotel del Luna - S1-E1
Factual error: The dead policewoman removes the bullet that she was shot in the head with. The bullet appears to be completely intact and undamaged as if never fired. Real bullets that have been fired into something or someone do not appear like this. (00:36:30)
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: 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: 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)
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)
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: 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.
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.
