Revealing mistake: In the beginning, the harem teacher and his pupils read the story (which becomes the movie) from the book Arabian Nights. The huge book propped up in front of the old man, though, is only an empty cover with no pages at all.
Revealing mistake: In the scene towards the beginning, when the Chinese mob are talking in the car junk yard, the Chinese guy about to be crushed to death is begging for mercy. While the Chinese mob are talking, when the camera pans to the guy about to be killed, you can clearly see that it's a dummy, then in the next shot it's the real guy again.
