There's 54 years of X-Men comics by now, so there are a lot of characters to explore.

I always feel like every film takes the franchise and hangs it in the balance.

There is no one who can move and mime and clown like Bill [Irwin].And Aubrey Plaza, she gets to embody all these different characters. That's what's exciting about this show [X-men], is the unusual casting.

Matt's [Nix] is much more a part of just the world in terms of there are mutants, mutants are hated and there are Sentinels - though very different from what we've seen before. You feel like you're here in the X-Men world.

The thematic core of X-Men is tolerance. It's that for those of us who are different in any way - in a big way - whether it's you're a minority, you're a woman, you're a Muslim, you are suppressed or marginalized; it can go the whole spectrum, but even if you are shy or you feel like an outsider, and X-Men are outsiders.

Somehow we allow, if a character goes to the dark side, if we're hooked into that character - I'm obsessed with Peaky Blinders. Those characters are awful, and yet you root for them. You love them! Same with Breaking Bad. That's not as easy in a feature.

With Legion, we're our own universe. It gives Noah [Hawley] the freedom to do what he wants to do. Because we play with so many different timelines, and we rebooted and not really rebooted and all that, we felt like, OK, we're going to throw it out there and hope the fans accept it.
