Fans are really important for me. And if they take pains to write me, it's the minimum that I answer myself.

My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.

I remember Paul [Dano] had said at one point that when he finished this film [Swiss Army Man] was the strongest he'd ever been just from lugging me around for [several] weeks.

I sort of try to read the books when they come out impartially and not make up my mind, but the fact is when I was reading the sixth, 'Harry Potter And The Half-Blood Prince', there were bits in there where I was going, 'God, I would love to do that because it's so good'.

My dad believes in God, I think. I'm not sure if my mom does. I don't.

I know it wouldn't seem like I've had a lot of failure in my career, but there are things that I regard as failures, when I look at certain performances and go, 'That's not good enough.'

I still have issues around forgetting that it's my life and if I want to do something, I can do it.
