Revealing mistake: When the elephants are making fun of Dumbo in the train caboose, Dumbo's mother pulls a pin which causes the stall door above the other elephants to fall. When the door bounces back up, you can see that the animators forgot to draw the elephants' heads and trunks and only their bodies are visible.
Revealing mistake: Halfway through the movie, Alta is swimming in the pond, supposedly nude. However, when she climbs out, she can be seen wearing a flesh-covered swimsuit. (00:45:15)
Suggested correction: Alta never said she was naked. She didn't know what a bathing suit was and Adams assumed she was naked.
Revealing mistake: From the front view of Karen's gun, you can see empty chambers.
Revealing mistake: During the first shot of Larry being pushed out of the car, it's blatantly a stunt double who is taller, thinner and has shorter hair than the actor.

Revealing mistake: When the camera pans across Kareem Abdul Jabar's dead body sprawled out on the steps, the corpse blinks.
Revealing mistake: When Crewe dumps the car in the river, you can see the wire attached to it that was used to pull it out of the water. Burt Reynolds mentions it on the DVD commentary.

Revealing mistake: During the end scooter sequence along the cliff tops, you can clearly make out wheel tracks stretching out ahead of Phil Daniels' bike, yet he hasn't been over that ground yet - these are presumably left-overs from a previous take?
Revealing mistake: Near the end of the film, after the shootout, there's a shot with the camera zooming in on a newspaper at Will Smith's front door. If you pause it right once the headline fills the top of the screen, you'll notice all the paragraphs are just repeated, word for word. Additionally the word "received" is misspelled.
Revealing mistake: Just after Li Mu Bai tells Shu Lien that they are very close to her headquarters and that she should check in, we are treated to two 'time pass' shots of forest. The second of these features some very obvious power or telephone lines in the lower right corner of the screen. (01:22:40)
Revealing mistake: When Mia is playing softball in gym class, and the ball she hits at Josh hits him in the groin, he actually gets hit in the stomach. (01:24:45)

Revealing mistake: When Charlie and Daisy get the flat and have to hitch-hike, and Daisy takes off her shoes to run to the car that has stopped, the bottoms of her feet are already filthy (presumably from having to do the scene over and over).
