Factual error: Before "classes" begin, the pilots are told that they would be flying against planes that are faster than their F-14's. The F-14's top airspeed is over 500 mph faster than the F-5's, and more than DOUBLE that of the A-4.

Factual error: During most of the basketball games, you can see an American flag in the background. This is not the problem, the problem is that it is hung wrong, the stars should always be on the top LEFT not RIGHT.

Factual error: The mounted machine gun fires far too many shots for the limited supply of ammo it has in the box attached to it.

Factual error: When Steve Martin dies with the mask on, the inflation bulbs (the little black bags that inflate and deflate) deflate completely. Actually they should INFLATE completely and stay that way. The gas is still on full blast and Steve is no longer inhaling (which would cause them to deflate). It was done only to emphasize Steve Martin's demise but it's factually incorrect.

Factual error: While using the phone in his cell, Dr. Lecktor asks an operator to dial a Maryland area code, but is then connected to the University of Chicago. (00:30:10)

Factual error: Right before Frank humiliates Dorothy for the first time, he blows out one of the gaslights in her apartment. That is never done in real life, for the same reason you would not blow out the pilot in your stove.

Factual error: When the Delta Force lands on a beach, prior to their assault, their landing craft is lit up like a christmas tree. The commandos wear dark uniforms and have blackened their faces, but they also carry bright white ropes around their chests. Some of them are scuba-divers, wearing yellow oxygen-tanks. In short, in the real world they would have been spotted within minutes.

Factual error: Teddy wears army boots that did not exist in 1959.

Factual error: When True Heart skydives down to Earth, she is wearing goggles with a wraparound strap. She takes these off and drops them in her backpack where Baby Swift Heart is hiding. When he pops up a split second later wearing the goggles, the strap is under his bonnet.

Factual error: When Nancy goes in a car in London to score drugs there is a political poster stating 'Labour Isn't Working'. This poster was used by the Conservative party in the 1979 general election - Nancy was killed 9 months prior to this election.

Factual error: At the very beginning of the film, Gunny Highway learns that he's being reassigned to the 2nd Marine Division. The 2nd Division, located at Camp Lejeune, North Carolina, is situated on the NC coast; there are no mountains in the immediate vicinity. However, when the Gunny trains his platoon, he does so in the hills of another Marine training camp located in California. There is a big difference between California and North Carolina.

Factual error: Bunny bites an aluminum beer can in half. Beer cans weren't aluminum until the mid 70s. He would have hurt his mouth on that one.

Factual error: Cruise is breaking and if you watch the eight ball after the break it's following the 5 into a pocket at the end of the table closest to Tom. Now the 8 ball didn't necessarily go in because they focus on the one ball, but in the next frame shot, there's no way it could be at the opposite end of the table like they show. (00:29:20)

Factual error: The movie they're watching in the theater, "The Fly", is shown backwards. The first scene they see should have happened after the last scene they see.

Factual error: When we first see Kurgan in modern day New York, he begins to assemble his sword in a motel room. The very fact that he is assembling his sword the way he is, snapping segments together, especially the blade itself, which is segmented in the middle, would make that quite possibly one of the weakest and most inefficient weapons a person could ever wield. Being that it is segmented the way it is, it is structurally weak, and a clash against another sword, or any hard surface for that matter, would break the segments apart easily.

Factual error: When Ack Ack is collecting shells on the beach for his father, he's really collecting shell casings... which should be where the guns are fired, not where the explosions are.

Factual error: The enemy planes described as Mig-23, are really Israel's Air Force IAI Kfir fighters.

Factual error: The clan people look nothing like Neanderthals, they look like Cro-Magnon with a little dirt on.

Factual error: When Fievel is being dressed by the pigeon there are two American flags in the background. The flags have too many stars for the mid 1880s, when the movie is set.

Factual error: During the karate tournament towards the end of the movie if you'll notice the American flags in the background you'll see that they are displayed improperly. Whether flags are being displayed horizontally or vertically, the stars should always be on the left side of the flag.
