Revealing mistake: When Louis is trying to get Gage off him near the end of the movie, as he's struggling in a few shots you can plainly see it's not really Gage but a dummy made to look like him. Looks like a doll. (01:33:35)
Revealing mistake: After Evolet got hit by the arrow and presumably dies, D'leh is staring at a mammoth. Behind the mammoth, you can see that the background is a picture.

(00:24:10)
Revealing mistake: When the Black Pearl swings alongside the Interceptor for the battle, Elizabeth shouts, "Fire all!" The next shot is from behind the lit cannon which is aimed at the Pearl and the following shot faces the Interceptor's cannon, as it goes off. In the shot facing the Interceptor, the raw wood scaffolding type beams are perfectly visible at the entire lower part of the screen, where the painted planks (below the gun ports, above the bilges) of the hull should be. (This is only visible on the video version.)
Revealing mistake: In several scenes Superman has fillings in his teeth.
Revealing mistake: When Fletcher is beating himself up he goes into a stall and squishes his head with a toilet seat. You can see that the white part underneath is made out of foam because it keeps squashing down.

Revealing mistake: There is a shot where the point of view of the camera is looking down at Christian and Toulouse from the opening in his ceiling. You can see John Leguizamo's legs behind him and that he is kneeling down. (00:06:00)

Revealing mistake: In scene at the brothel, with the senator and the dead prostitute, the supposedly dead body is breathing in the last shot of her, just after Tom Hagen says "it'll be as if she never existed". (01:15:30)
