23 X-Men Movie Mistakes You Probably Missed

15. Nobody Has Any Blood - X-Men: First Class

Another error relating to bodily damage, and this time a double header from Matthew Vaughan's series revitaliser, in which apparently nobody who dies has any blood.

Firstly, the knife that Erik uses to slay the two Nazi officers hiding in Argentina remains pristine and bloodless despite having stabbed (and killed) one of them, and twice stabbed the hand of the other (who might be the worst actor in all of comic book movie history.)

And then, if those two examples aren't enough, it seems that Professor X doesn't have any blood either, as when Magneto removes the bullet that has just paralysed his friend, it is remarkably unbloody,, despite having burrowed deep enough to cause that much damage.
