Character mistake: In the Air Force One scene, when lightning destroys one of the plane's engines, one of the pilots tells a co-pilot to inform Metropolis Airport that the president is on board the plane. The crew is unnecessarily repeating themselves: just a few moments before, they radioed in that "Air Force One" was on approach; the plane would only have that call sign if the president was on board.
Character mistake: When giving Eggsy a tour, Galahad tells him that Oxfords are any formal shoe with open lacing. This is incorrect as Oxfords have closed lacing.
Character mistake: When Rosie sticks her revolver in Bond's room and Bond flips her onto the bed, Bond incorrectly identifies the gun as a Smith and Wesson .38 which would make it a model 10 or 15. It was actually a Model 19 .357 Magnum.
Character mistake: Captain McCrea tells the passengers that it's the 700th anniversary of the Axiom's first flight. The Axiom has been in flight for 255,642 days. Actually, 700 years is 255,675 days. That figure includes the additional day in 175 leap years.
Suggested correction: Leap years only occur because of the earth's rotation around the sun. As the AXIOM is in space, there is no need to correct for the earth's rotation.
First, rotation is the spin of the Earth (which cause day and night). Revolution is the earth orbiting the sun (which causes years). However, this correction is not valid on the premise you're trying to present. Many films set in space still use Earth time, so a day is 24-hours, even though they're in space and there is no sunrise and sunset (although it's stated the Axiom operates on a 25-hour day). So they would use Earth's year, which takes 365.256 days. Since the Axiom isn't orbiting the Sun, it wouldn't experience a year, so they're using something else. The fact that they're slightly off suggests it's a writing mistake and there's no evidence they use an arbitrary 365.203 day year.
Character mistake: At the meeting of the MVD and FBI where they are discussing Terek's hiding place, she mentions that he's in the town of Porvoo and that it is 60 kilometers west Helsinki. Porvoo is actually 50 kilometers northeast of Helsinki. (00:12:45)

Character mistake: After the things let the dog out, Larry calls Joan and tells her that the kids let him out, and he will get him (the dog). Later, when he's downtown with the dog, he has the line about "when Joan finds out you've escaped, Conrad's out and I'm in". Where is the surprise? He already called her, so she knows!
Character mistake: The Matterass twins are playing a video game, and they argue about whether to destroy Milwaukee or Minneapolis. They decide on Milwaukee but destroy Hibbing Minnesota.
Character mistake: When James enters and exits the laboratory, the door has a sign on it that warns for radioactive materials. The laboratory actually contains a biological weapon. Therefore the door should be marked with a bio-hazard symbol. (00:41:00 - 00:42:00)
Character mistake: When Curtin shoots Dobbs, the two shots are close together in time. When Curtin explains it he says that he was shot and falls. Then Dobbs shoots him again. This takes time but the shots were fired very quickly.
Character mistake: Buster and June are watching TV, and he says, "Hey, Julie" (the actress' real name). (00:08:07)
Character mistake: Hellboy's stone hand is on the wrong side when he's fighting the first giant. (00:32:50)

Character mistake: Why is Electra using Windows 2000 (still in beta at the time) to survey her oil empire? (I think it's just after she's asked M to come and help her) You shouldn't use beta software for anything important....
