Factual error: In every scene where knights collide on the lyst, you see their lances in one hand and the reins to their horse in the other. When knights jousted, they would drop their reins before impact so that a severe impact would not cause them to jerk the reins or become entangled in them causing more damage to themselves or the horse.
Factual error: Jesse James' mother in real life outlived him by several years following his murder.
Factual error: When Gandolfini has the shoot-out with the black assassin, it just doesn't make any sense that the cops who are nearby investigating the "suicide" of Gandolfini's boyfriend don't hear the gunshots and get involved. If the guns had silencers, the whole scene would be more sensible. Come to think of it, the sound-effects used in the shootings sound much like silenced shots but it shows that both weapons are unsilenced.
Factual error: In the fight scene in Lara's garage, she rides her motorbike towards the guy attacking her, does a front wheelie and knocks him out with the rear wheel by braking and turning the bike on its front wheel. The back end of the bike then gently lowers itself to the ground, rather than dropping heavily under the force of gravity.
Factual error: One scene shows Muslims in prayer. There, the Muslims go from standing to getting on their knees. The problem with this is while in prayer, Muslims never go directly from standing to being on their knees. First, they would go bend over into a bow with their back perpendicular to their legs, then they would stand again, then go into prostration (on their knees while placing their forehead and nose on the ground) then they would go to to sitting up right on their knees.
Factual error: When the knockaround guys are riding in their rented vehicle from Wibaux, Montana, their license plate starts with a J and is followed by several numbers. In Montana, license plates start with one or two numbers, followed by a P or a T, then four more numbers and one more letter at the end.
Factual error: When they get to western Nebraska, there are several scenes showing a mountain range in the background. There are no mountains anywhere in Nebraska.
Factual error: The horn on the LT's Range Rover is at the end of the signal lever not in the middle of the steering wheel as shown.
Factual error: Burt claims his watch updates its time "by connecting directly to the cesium clock in Colorado via ultrasonic frequency." Later the graboids home in on him by the ultrasonic sound emitted by his watch. Firstly, radio controlled watches update their time by receiving signals, but they don't emit any signals - the battery would be way too weak for two-way communication. Secondly, they work on radio waves, not sonic waves. Thirdly, if a hypothetical time transmitter did work on ultrasonics, the smallest distance between Colorado and Nevada is some 435 km (around 270 mi). An ultrasonic signal strong enough to reach that far would probably be deadly within a sizable range around the transmitter. (00:08:20)
Factual error: When Pootie is leaving Biggie Shorty's house, he says he is going away. Biggie Shorty asks where, to which Pootie replies he doesn't know. Biggie Shorty says that she has a home in the country and Pootie can stay there. (She even says South Carolina I think). Later in the movie after Pootie has gone to the country home, in the scene where the Sheriff introduces Pootie to his daughter, you can clearly see a NJ Turnpike sticker in the store window behind the Sheriff. The NJ Turnpike does not run through South Carolina, it is in New Jersey.
Factual error: The corporal mess steward addresses the sergeants as 'sir'. British sergeants are never addressed as 'sir'.
Factual error: Milo says Audrey is a "teenager". Which she is, but this is 1914! People didn't use that word back then. He probably should have said "adolescent" or something.
Factual error: The main character, a petite flight attendant, cocks the charging handle on a Mini-Uzi. The weapon had previously fired rounds so her action would eject a live round or in the event of a smokestack jam - a spent shell. Neither happened.
Factual error: The Kiss of the Dragon acupuncture point, known as "Point 15," is in a delicate area of the spinal column, a little below the second cervical vertebra. It's a definite knock-out target in fighting, and it can even be a lethal target. But Jet Li's explanation that it somehow prevents blood from flowing away from the brain is pure nonsense.
Factual error: Just before the cross scene a guard is holding an AK47 which was not invented until 1947.
Factual error: The canteens used by US troops in a couple of the scenes are the wrong type. The twin handle design M1956 came out in the mid 1950s.
Factual error: The shot of the plane in the Melbourne airport before it took off, and the one in Los Angeles after it lands are of the same place.
