IGN Interviewer: James McAvoy was talking about Charles and Erik being like Martin Luther King and Malcolm X in their approach to the problem of humans and mutants living side-by-side - would you agree with that?
Michael Fassbender: If that's what he said, then yeah, I like it. That sounds good. It's actually a good way to summarise it. But also, I think that Charles is just horny, and just trying to get laid. Throughout the film. He's like 'human beings are cool, give them a chance' because he just wants to have human being sex. He doesn't want to have mutant sex. Whereas Erik really gets off on mutant sex.
