Factual error: When the gang follows Ben Ravencrift home, they cross over a long bridge supposed to signify Brooklyn, but is in fact, The Golden Gate Bridge in San Francisco.
Factual error: The plot revolves on finding a matching organ compatible with Nora. Practically the only issue presented about it is the blood type compatibility, so let's go by that logic. In a misconception happening in so many works of fiction, the fact that she is an AB - is listed as a terrible problem because of how rare it is. It is indeed the rarest blood type in most parts of the world, but it's also the universal receiver and compatible with every other group.
Factual error: Sailing ships in harbor always have their sails furled and stowed, not set. All the ships in the city's harbor have their sails set. Would never happen.
Factual error: It's a superhero movie, but the human Catwoman escapes Batman by jumping off the building, onto a train moving at full speed, in a fall that is shown taking at least 10 floors (first shot, she is still upside down) + another 10 (when she flips so she can land on her feet). Over twenty floors of casual, unassisted freefall jump feel a little over the top already, and again, it's on the top of a moving train, that alone should be impossible to happen the way it does here, not affected by the lateral speed of the train at all. (00:10:40)
Factual error: When the Peanuts gang got to Victoria station, Travel Center is spelled the American way. Since it's England it should be "centre" (00:24:55)
Factual error: Remy sniffs the messed-up soup and almost throws up. Rats can't retch.
Factual error: All Arabic texts in the film suffer from wrong directional rendering. Arabic is a right-to-left language. Its letters have different joined and disjoined forms. The film, however, has rendered Arabic texts from left to right in disjoined letters. These texts aren't semantically wrong, though. For example, deciphering the Arabic message at 0:40:45 point gives "أليس "التنين فنان؟ Translation: "Isn't the Dragon an artist?" The film has even adopted a good font for them.
Factual error: The drum kit that Courtney plays at the concert is wrong. It has too many cymbals, two bass drums (one is unneeded) and she didn't kick the pedals to play the bass drum and cymbals.
Factual error: When Merlin and Arthur are squirrels Merlin says squirrels mate for life, which is not true. Squirrels are promiscuous.
Factual error: Steve Trevor tells Aquaman that he is a Colonel in the US Army. But he is wearing First Lieutenant bars on his uniform.
Factual error: When the boy sends the letter, it already has a postmark.
Factual error: Even if he was falling hard, Mandible still would've survived hitting the overturned root, as ants do not have much body mass.
Factual error: The film gets basic physics wrong while trying to depict relativity. Buzz Lightyear leaves T'Kani Prime for a trip around its sun, travels with near-light speed, and returns four years later. This could only have happened if T'Kani Prime's sun were at least two lightyears away! It gets more ridiculous. Buzz's last trip takes 26 years, even though he has traveled at faster-than-light speed. Overall, T'Kani Prime is experiencing either a mysterious time slow-down or a rapid orbit expansion.
Factual error: If there was that much of a famine in the pack, the Omega wolves would surely have already died of hunger.
Factual error: Apparently, Ratigan had to cross the River Thames to reach Big Ben from Buckingham Palace as evidenced by him tossing Fidget into the river before taking reign of the blimp. However, the two landmarks are on the same side of the river.
Suggested correction: Ratigan changed direction multiple times during the chase because he was trying to get away from Basil. He may have flown away from that side of the river, but then after changing direction he flew across to the side he came from again.
