As an actor, to be part of that story's [Marvel univerce ] terrific. I've enjoyed it so much as a fan and now I'm getting to have a go myself.

I play enough other mad people, as well and some sane people, to vary the palette of what's scrabbling around in my head and soul to bring to the floor, as a storyteller.

I keep myself amused and others confused

When you're a kid, 'Star Trek' is a slower burn. It's funny, it's entertaining, but it also has a maturity about it - which is its universal appeal, I think.

I'm not one for doing the children's party version: "Hi, I'm a character in a movie and now I'm in reality!" I was doing the last shot of the film before reshoots outside their shop. I was starting my run into the frame and I thought, "You are literally ending where this began. The loop of serendipity's too much to not go in and acknowledge it." I just wanted to see the look on their faces.

This is an odd profession, and sometimes people get jealous, but I haven't really experienced any of that. Everyone's been really happy for me, which is really, really great.

The guy [Doctor Strange], he's like most of us, he's uncorrupted flesh from the beginning of his life, he's somebody who's not marked with original sin or any kind of crap like that. He's somebody who's come into this world and had experiences that have shaped him to the point that we first meet him. There's always got to be leverage. I think there is some clear explanation of that within this film, but potentially further down the line...for more of that to come out as well.
