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

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.

At a certain point people want to see other movies besides comic book movies so you have to be really careful what you're going to pick, and how many are going to be released within a year.

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.

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

In the Marvel world, some characters have similar powers. Initially some people might bump up against it, but if they really looked into the X-Men world they would see that characters do share similar powers.
