Factual error: How is it that when Sly comes out of the freezing, icy water, his hair and clothes are bone dry? I don't know too much about hypothermia, but I would imagine that his fairly thin sweater isn't wind proof. I'm sure by the time the movie ended, he would be suffering from more symptoms of hypothermia other than chattering teeth.
Factual error: When Jean-Claude is chased by the helicopter in the woods alongside the river, the man in the helicopter fires a MP5 machinegun, but it causes huge explosions, this is impossible, it's not a grenade launcher!
Factual error: In the scene just before the fight at the O.K. Corral, Wyatt is talking to his brothers and Doc on the porch of the town marshal's office. There is an American flag flying behind him with 50 stars on it when in fact there were only 38 stars on the flag in 1881.
Factual error: When Cruz is schooling Jaunito about "Quetzalcoatl" in the background the song "Low Rider" is playing. The timeline states it's 1972, but the song wasn't released until 1975. (00:08:10)
Factual error: The display on John Spartan's cryogenic reads, "August 3, 2032," which will fall on a Tuesday. Later that same day, Huxley says to Warden Smithers, "It's a beautiful Monday morning" (00:11:30 - 00:12:15)
Factual error: During the car chase at the beginning, they are chasing a car on Bigelow Blvd., less than a mile from downtown Pittsburgh and we see a big, brick hill they chase down. This hill is actually in Duquesne, PA more than ten miles south east of Pittsburgh. Then as you're watching they are still in the same area as Bigelow Blvd., in the Polish Hill section of Pittsburgh.
Factual error: In the early scene where Dennis Nedry meets a man to plan the embryo theft, the subtitle says that they are in San José, Costa Rica. However, the sleepy coastal town in the movie within sight of the ocean bears no resemblance to the real San José (a cosmopolitan capital of almost 1 million people, situated 50 miles from either coast). Even the book makes this error. (00:13:10 - 00:14:45)
Factual error: Not long into the film, D'Artagnan jumps in some hay. There's a flag of the province of Québec (Canada) visible in the background. This film is set in France at a time this flag didn't even exist.
Factual error: Most of the time the boys have no visible breaths, even though they're in a freezing climate.
Factual error: When Nina was given the assignment in the restaurant in the guise of a dinner outing,she was handed a a box with a pistol in it. That pistol was an Olympic-grade target pistol used in international competition. That type of firearms does NOT hold 8 rounds,and she fired 8 rounds before re-loading.
Factual error: When Robocop first flies into the the battle at the end of the movie, the whine from his jetpack causes the glass in some windows to blow outwards. Considering the sound waves are hitting the glass from the outside of the windows, they should be blown inwards not outwards.
Factual error: When the FBI agents are shooting Jason, 2 things happen that shouldn't, 1. His machete is shot but doesn't move, the force from the bullet would cause the knife to move. 2. When the bullets hit the knife, they cause sparks, bullets never cause sparks when they hit metal.
Factual error: During the scene where Bruce leaves his girlfriend's parents home, it's raining. He leaves in a huff on his motorcycle and you can clearly hear the sound of screeching rubber on the pavement. Peeling out and making this sound would not have been possible in a rainstorm.
Factual error: In the opening sequence, the range for the shot is confirmed as 650 yards. Moments before the shot, AFTER he had his target centered in his scope, Berenger swings the muzzle of the rifle at least 10 degrees. At 650 yards a change of only a single degree in the angle of the muzzle to the target would mean that the target would have to move 11.34 yards laterally in order for the shot to hit. If Berenger actually had to swing his rifle ten degrees in the span of a second in order to keep his target in view, that would mean the target was sprinting at a speed of 340.32 feet per second, or about 232 miles per hour, and had covered 113.44 yards during that time. Absolutely impossible.
Factual error: When the robbers are breaking through the vault door, they look to be using an oxygen lance which in reality would cause that entire room to be filled with smoke and fumes in seconds.
Factual error: During the car chase that leads to the tunnel, there are several freeway signs pointing to Murphy, North Carolina, and the film is set in Chicago.
Factual error: The beginning of the movie takes place in Las Vegas, but during a tracking shot of the main villain, Bracus, leaving his helicopter, the Los Angeles skyline is visible from the helipad at the top of the building. (00:03:55)
Factual error: In the end scene on the pier, Robert Duvall has Michael Douglas at gunpoint. A closeup of the revolver's chambers shows them to be empty of bullets; yet Duvall then shoots Douglas dead.
Factual error: The movie feels the need to justify the fact that everyone in 1603 Japan happens to speak English (something most kid movies just gloss over) by explaining that they are trading with Great Britain, and therefore the locals picked up the language. That's real cute, but also blatantly false. Trade with the British empire was rather sparse, mostly with Dutch mediation, and knowledge of the English language was practically nonexistent - here, any peasant and even kids are practically bilingual.
