I'm possibly a very morbid person but I think about death a lot. I don't know if it's maybe from being on films that's often playing Harry [Potter] or I just think it's a natural thing that I have. It's something that I think about just because it's fascinating in a very alien kind of way.

I'm not too worried about humanity in the future. I think we've got an innate ability as a species to self-correct.

Somebody I love and have a huge amount of respect for once told me something that, to this day, I don't really think I understand. It was probably toward the end of Harry Potter, and they were talking to me about afterwards and that kind of stuff. And they were saying, "You need to think of yourself as a brand and you need to protect that brand." I just don't understand what that really means in terms of being an actor, and I also think I would find that a slightly soul-destroying way to look at myself.

I just have this fear that I'll get on stage and there'll be that brief moment of adrenalin and I'll forget my line.

Every day I would come to set [of Swiss Army Man] going like, "How are we going to do this?".

I'm not clean or even vaguely pleasant to be around in a domestic situation.

I'm very comfortable discussing my personal life, because it's so boring.
