Factual error: Legitimate religious institutions are not subject to property taxes.
Factual error: The Bandit is in a showdown with Buford T. Justice in a desert mountain range shortly after crossing into Texas. There are no desert mountain ranges in eastern Texas.
Factual error: After Superman accidentally frees the phantom zone villains with the exploding hydrogen bomb, they start flying towards the moon. The sleeves in their clothes can be seen fluttering around. This would be impossible because there is no air in outer space, hence nothing to cause resistance against the clothes.
Factual error: During all the major battle scenes involving tanks the Germans are using post-WWII tanks. The turret looks a bit like the M10 Wolverine with a top cover.
Factual error: A meteorite falls onto Munson's bed, setting fire to it. He covers it up with blankets. But the meteorite is still red hot and would surely burn through, and set fire to his bed again.
Factual error: When they first meet, Rodrigues tells Blackthorne that aboard his ship there is plenty of food and grog. The problem is that grog was not "invented" until 1740, when it was introduced into the British Navy by Admiral Edward Vernon, who was nicknamed "Old Grog" because of his habit of wearing a grogram coat.
Factual error: There are three major mistakes regarding gravity in the escape sequence in the asteroid field. Han and Chewie take the Millennium Falcon to refuge on an asteroid that, while visually huge, is still far too tiny to have sufficient gravity to allow humans to walk in anything like a normal fashion; yet, they walk normally both inside and outside of the ship. They also do not use pressurized suits outside of the ship, even though the asteroid's gravity should be far too weak to accumulate any significant atmospheric pressure; they use oxygen masks, but their blood should have boiled in near-zero atmospheric pressure. Finally, and most ridiculously, they fly straight down the giant cave worm's throat and land on the side of its throat (this is obvious in the shot where the Millennium Falcon lifts off and heads toward the toothy exit), and they get out and walk around on the side of its throat, which would mean the asteroid's gravity was impossibly perpendicular to its mass. (00:57:50)
Suggested correction: However, size isn't everything. The more mass an object has, the greater its gravitational field will be. Nothing is known of the asteroid's composition. It could have a high mass, resulting in a higher gravity than an equivalently sized body of lower mass. This would also address the atmosphere issue. Also, there is no evidence that the throat was vertical when they landed on it. Clearly, the creature was further down the tunnel perpendicular to the surface, then changed position as they flew out.
Factual error: When they find the safe they find it is watertight, but a watertight safe at that depth would have imploded from the pressure.
Factual error: The Hillman Minx car seen picking up Brits at Conchin railway station is at least a 1945 model. The film is set in 1943.
