Factual error: Throughout the film, most Japanese words are spelled in Katakana. In real-life Japanese, however, Katakana is exclusively used for foreign words adopted into Japanese language, like 'table', 'television' (mostly it is abbreviated to 'telebi') and 'racing car'. But in the film, even indiginous Japanese words such as 'samurai' are spelled in Katakana, not - as they should be - in Hiragana (the syllable system used for native words).

Factual error: Towards the end of the movie when Superman and Henshaw are fighting on the Watch Tower in space, Lois hits the sun shades to lower them so that direct sunlight can hit Superman and power him up. This is out in space with no atmosphere to filter the sunlight. The reason the blockers were there was for this reason, to keep the harmful unfiltered sun light from hitting people on the ship through the windows. However, she is able to stand there in the direct light after it's done and kiss and hold Superman without being hurt or burned by the intense direct unfiltered sunlight or its radiation.

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.
Factual error: When the magician has brought the crocodile home at the beginning of the movie and is trying to get him to sing, the crocodile is shivering because he's cold. The magician wraps him with a scarf and the crocodile warms up and is willing to sing. However, this would not work, as crocodiles are cold-blooded and unable to generate body heat. The crocodile would need a heat lamp or some other source to become warm again.

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)
