[Doctor Strange ] is slightly more specialised than Spider-Man or Superman or Batman, but he's very loved by people who know him.

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.

I've turned up to costume parties in the wrong costume. I've made social faux pas a plenty. I've put one foot in front of the other and fallen over.

I just want to bring people in a little bit to the idea of sitting down on a Sunday three consecutive weeks and having that water cooler moment that really was a sort of a national sensation in the U.K., 'cause it's kind of fun.

I'm not loyal to one genre. I want to mix it up.

I would love to just have the work do the talking. We're in positions where people ask us questions; they want to know about more than just the work. And it can go into areas where I've completely shot my mouth off, whether it's too much about my private life or being too opinionated about things in the world. I think the better thing to do - I've learned this from people far wiser than me - is to do very good, quiet work behind closed doors.

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.
