BloodRayne (2005)

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.

Vladimir: My companion seems to be missing. I do not know what has become of him.

Trivia: Laura Bailey, who provided the voice of BloodRayne in the original video game, hated the film.
