Character mistake: When Kyle steals the police officer's gun and asks him what the date is, the officer replies "12th, May, Thursday". The film is set in 1984. May 12th, 1984 was a Saturday. (00:08:25)
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: The word "Storyboard" in "Storyboard Artists" during the end titles is misspelled "Stroryboard". (02:05:00)
Character mistake: On two occasions throughout the film, Kraven's accent changes - once when he is talking to Lucian near the beginning of the movie and near the end of the movie when he is telling Selene that Viktor killed her family.
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: When McCall put his gun to his head and pulled the trigger, he's saddened that it didn't go off. Most handguns (including the one he was using), after the last round is fired, the slide locks to the rear. He would not have made the mistake of thinking it was loaded.
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 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: 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: 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: 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: When Doug Masters approaches his aircraft at the airfield before racing 'The Snake', Col Sinclair has a right hand access panel open on Doug's Cessna 150 upper engine cowling and is allegedly working on the fuel system saying "As lean as you were runnin', if it went into a stall, you woulda lost your engine, and would never been able to pull it out." The carburetor, gascolator, throttle linkage and carburetor control lines are on the bottom of the engine (Continental O-200). The panel he closes after sticking bubble gum on accesses the battery, the right hand magneto and the oil dipstick. Not only did Col Sinclair not do what he said he said he did without a sign-off in the aircraft's logbook, it would be totally unnecessary, as aviation updraft carburetors use a cockpit or engine controlled fuel mixture control that would have simply been left in 'full rich' position after engine start for the altitudes the aircraft would have been flying. And stalling is an aerodynamic condition of angle of attack being exceeded or insufficient airflow over flight surfaces, not fuel starvation, which is the condition being addressed. (00:11:30 - 00:12:30)
Suggested correction: "Full rich at that altitude." Doubt it. It's a hot desert and almost certainly has altitude above sea level. The "lean for best power" rule would apply. The engine might not actually give any performance or even run at full rich.
Character mistake: When Curtis and Connie stop at the first gas station, the word diesel is misspelled as disel.
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: 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: 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: 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: 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: When Chris joins the Marine unit they are going to breach a door. Chris removes his shooting hand from his weapon to signal the breacher. He would have used his support hand.
