Continuity mistake: When Sugar Bear flies through the air and lands on Truck at the end dance off, Trucks legs bend backwards underneath him. When Sugar Bear gets off of him, he's now flat but his legs are laid straight out instead of bent.
Factual error: The part of the movie where they have had the morning updates at the police station, Richard Gere later walks on the sidewalk and stares deliberately at a pair of Muslims praying. The sun is shining on the backs of the Muslims heads indicating that they are facing west even though Mecca would be off to a much more easterly direction from Brooklyn.
Continuity mistake: When Lotte is tied down to the altar and is talking to Jimmy, the cut on her face alters constantly from the left cheek and right cheek throughout the conversation.
Continuity mistake: During the fight in the bathroom, Zoe and the villain break a bathroom stall door and side-wall down. In the next shot the door is back up in its original position. It is the same door that is beside the urinal, not another stall, as it's a small bathroom with only one stall and urinal. (00:28:30 - 00:30:00)
Factual error: The credits list several of the characters as "Arab." But the film is set in Afghanistan and the Afghans are not Arabs.
Revealing mistake: When Mr Goodall is attacking the bloke near the start, he is supposed to be hitting the other man really hard, but doesn't come close to hitting him.
Continuity mistake: When Lex Luthor has his battle suit on and fighting Superman and Batman, the head and neck piece change dramatically and constantly. Sometimes the piece surrounds his head, leaving plenty of room and sometimes his head sticks out over the piece. And it's not a matter of angles, because in some shots, everything being the same, the side piece remains at ear level and his head is either above or below the head piece.
Other mistake: When the Amazons interrogate Steve they don't know the meaning of the word "crap" yet they know one of the definitions of the word "rack."
Suggested correction: Just because they understand some slang, doesn't mean they should understand all slang.
Well if they're an ancient race then how do they know of the use of the word rack regarding female anatomy? One of them went out into the modern world and learned this? Hera tell them this? Maybe they got internet or a modern dictionary?
Well obviously they know stuff about the modern world. Diana could speak Dutch fluently, not Old Dutch either, but modern Dutch. So they do get information or else she wouldn't have known that. This would include slang.
Factual error: Chun-Li's father sets wine on fire. This is not possible because the alcohol content is not high enough.
Plot hole: The NSA guy states that Van Ryberg "knows more about remote controlled attack drones than anyone on the planet". A bold claim, considering he was only a Specialist in the Army, would have been trained by someone more technically competent on Reaper and Predator drones, and is not likely to know more about them than the company responsible for their manufacture in the first place, which makes his inclusion in a Top Secret affair unlikely and improbable.
Revealing mistake: When Steven Seagal makes his triumphant entrance in the credits, his sword misses the first zombie he supposedly hacks (right after "Written by"), by a mile. (00:03:20)
