I think I tried to steal a Mars bar once from a shop but then I went and put it back.

My parents are left-wing, and I would describe myself as that. But also, you know what? I wouldn't describe myself as that. Because I don't have to. Because I'm not a political party. Most people are a little bit of each, and we change our mind on various issues.

My idea of relaxation is not lying down by a beach. I have to move around, do stuff. Though I'm a massive quiz show person.

I see myself doing Harry Potter films as long as I'm enjoying it and as long as they are going to challenge me as an actor. I want to be an actor - it's my aspiration - so I want to do other films. I want to write something and I want to direct something!

There's never enough time to do nothing!

Franchises aren't to be avoided. They can be exciting, and they give you opportunities to do other films.

Those things [t hydraulic penises and prosthetic butts and all that] can be what's genuinely shocking about the movie [Swiss Army Man] because people wouldn't expect to be moved by any of it.
