Other mistake: Michelle Rodriguez's accent changes several times, not only throughout the movie, but sometimes within the same scene.
Revealing mistake: In the battle at the cathedral and at the end of the film when the footage is repeated, we see people hacking away at a torn up, dead body. The problem is their swords and axes are not damaging the body at all, revealing everything is a prop of some sort.
Revealing mistake: During the montage at the end of the film, we see the owner of the side-show getting killed, but the problem is the blood shooting from his body is not actually coming from his body, but shooting up from a device in front of him. You can even see steam from compressed air used to shoot the blood up.
Revealing mistake: In the director's cut DVD, during the big battle at the cathedral, when the man is cut in half, you can see a sheet behind his fake chopped-off legs covering his "real" legs.
Revealing mistake: There is never a bladed weapon in this movie that isn't blunt. Most of the camera angles are close enough to show that their swords were not sharpened.
Revealing mistake: The carnival side-show owner's sword is obviously a prop, as it appears to look almost like tinfoil.
