X-Men's Charles Xavier hasn't finished being broken down, says James McAvoy

We last saw Charles Xavier forever physically altered by his dear friend Erik Lehnsherr — so what's next for the leader of the X-Men? The actor who played the young Professor X, James McAvoy has a few ideas about Charles' future. And it starts with deflating Xavier's giant mutant ego.

We were lucky enough to speak with McAvoy one-on-one, as part of the press day for his new animated film Arthur Christmas, and he told us what he imagines will happen in the next X-Men.

Michael Fassbender recently stated that he wants more Charles Xavier in the X-Men: First Class sequel. In your opinion, where are our heroes in the sequel? Where will we find Charles and Erik?

I don't know where we find Erik — it's kind of defined at the end of the film that he's a bad guy. I can't really speak for him, but I know that with Charles, you either have to write him out of the movie or give him an interesting story. He can't just become the guy that we saw in the first three movies. He just had two major things happen to him. He's lost his best friend, essentially, and he's just been paralyzed from the waist down. Which is just a huge, huge blow to his considerable ego. So he's got to deal with that.

And I don't think we can just brush over that and go, "yeah I'm in a wheelchair now," because Professor X is in a wheelchair. You've got to deal with that, I don't care if he's a superhero and has brain powers or not, he's just had a huge part of his physical life taken away from him, by someone he cares about more than anyone else. So he's got to deal with that. That's part of the interesting ideas that we're talking about with Matthew [Vaughn], that Matthew's very excited about which I think is fantastic, but I can't really get into them with you because they may (or may not) form the spine of the story.

Would you like to be in the sequel? Have you said yes?

I would definitely like to be in the sequel, but the truth as well that I'm bound to be in the sequel by a contract that says we do three films. So if Fox decides we're doing it, then I don't have a choice. But I would still like to, I had a great time with Matthew and Michael, that was a great threesome to work with and really sort of carve out a new beginning for those two characters. So hopefully we'll have the same kind of joy on the set. The good thing is, I don't think Fox is rushing into it just because it did well. They want to make sure they get a good script, because if you can't get a good story there's no point in doing it. It can be a stand-alone film if we can't figure out a good story.

There's plenty of story left for Charles in between where he is now and where we've seen him before. I hope he isn't written off.

That's what Matthew is talking about, he's come up with a particularly interesting idea, last time I spoke with him. So he's pitching that to Fox, and they've basically just got to write the script.
