Is Fassbender playing himself AND his ancient ancestor?
.... why?
An ancestor from 4 generations back would only share 1/16 of their genes with you, so an ancestor from hundreds of years ago... should look identical to you... because they're slightly related?
Stupidest thing I've ever seen. Do movies have people play their own parents? That would make more sense than this, because at least parents share half the DNA with their kid.
I hope this is the stupidest aspect of the film, because if not, we're gonna have some major problems on our hands.
