Character mistake: Tej mentions that the BMWs they used were factory-line, ie. unmodified. Hobbs then says that they were twin-turbo V8s "spitting out 560 ponies". The BMW M5s they have are E60 models (2005-2010) powered by a naturally aspirated 5.0 liter V10, producing 507 horsepower. (00:38:30)
Character mistake: In the courtyard of the castle there is an anti-aircraft gun. You could probably not find a worse place for a gun like that even if you tried (except maybe if you put it inside, in a windowless room). In the position it is placed it can only fire at targets directly above the castle. What you want to do is fire at targets before they reach the castle. It would be better if they placed it on the roof, or even near the village below.
Character mistake: When Tris and Christina are going to rescue Four, Tris asks how to use the drones. When Christina tells her that she must use her left hand she can be seen using her right hand to control them.
Character mistake: In a scene when Watney is recording his video log, he imagines what would happen if his pressurized shelter suddenly would break. He concludes that he would implode, but the correct wording would be explode.
Character mistake: The word "Storyboard" in "Storyboard Artists" during the end titles is misspelled "Stroryboard". (02:05:00)
Character mistake: The police are marching Matrix out of the gun shop, they didn't even put hand-cuffs on him! I think I would put hand-cuffs on a guy who just smashed open a gun shop and was stealing all the guns he could get into his hands. (00:55:50)
Character mistake: When Maximus is talking to Marcus Aerelius, he mentions that his wife has black hair. But in the scenes where we see her, she actually has brown hair. (00:24:40)
Character mistake: Those are the most haphazardly secured cases of nitro I've ever seen in a movie. Couldn't they spare a shoelace or duct tape to secure the top?
Character mistake: At the end of film when the Chinese refugees are being unloaded from the lorry a policeman helps an injured man off, then goes back to help others. The injured man sits and then lies down. As he does, the policeman that helped him throws a bag without looking, which hits the injured man.
Character mistake: More than once the crew of the submarine salute the Captain while uncovered in the hallways of the sub. Sailors never salute without their cover on.
Character mistake: Some characters use the letter "s" at the end of a Pokémon's name when the plural of a Pokémon is just its name. The best example is when Pikachu says, "Roger must've sent the Greninjas to cause the car crash." Being a Pokémon himself, there's no way Pikachu, out of all characters, would say that.
Character mistake: Dylan is showing Agent Cowan and the FBI director the pictures of the pigeons and Dylan and Cowan start arguing, while the FBI director continues to look at the evidence on the Four Horsemen. Whilst looking there is an article reading "FBI Investigation Stalls." On the first column of the article, it is mentioned that all four members of the Four Horsemen, J. Daniel Atlas, Henley Reeves, Merritt McKinney and Jack Wilder, all disappeared into thin air at the final magic show, and gave the audience fake dollar bills. By the time of the final magic show, Jack had faked his death and was presumed dead, so only three members of the Horsemen were present, not four. (00:08:55)
Character mistake: When Mike's wife is watching the news about the oil rig on fire, you can see the TV with part of the U.S. map on it and 'Mississippi' is misspelled as Missisippi. (01:09:10)
Character mistake: There is no way an operative of Q's position and experience would have plugged a device taken from a bad guy into their network. Especially as they had had a security hack only a few days earlier, and this was a security establishment. It would have been thoroughly tested and checked on a stand-alone, air-gapped setup first.
Character mistake: Towards the start, when Emily mentions that the presidential limo is based on a Cadillac CTS, she is wrong. The Cadillac DTS is the basis for the car, even though it does not carry a model designation anymore. (00:14:00)
Character mistake: When Bruce is looking at Chase's various clippings of Batman on her desk while she's tending to the tea kettle, there is a paper that says "Diagnosis Form #39," and just above it, the word "schizophrenic" is incorrectly spelled as either "schizofrenic" or "schizoprenic" (a metal clip is partially covering the last six letters of the word, so it's hard to determine whether it's an "f" or a lone "p" where the "ph" should be). (01:03:11 - 01:03:32)
Character mistake: Sybok tells Kirk that no one believed the world was round until Columbus proved it. Someone who studied at the Vulcan Academy should know that the Greek philosophers had proved the world was round and calculated its circumference centuries earlier. Columbus never set out to prove the world was round, just to find a shortcut to India.
Character mistake: Jonesy says he read about Amber going to West Point. She was a Marine, and not in the Army, which is what West Point is for.
Character mistake: All the characters wearing gas masks are wearing them with the straps over the hoods. I was army trained, and you always wear the mask next to the skin for best seal, with the hood over the top.
Character mistake: Dave's wife refers to McCall as his "Army buddy" - but the pictures in McCall's house on the shore show him to be a Marine. Not a generalisation a Marine would make.
