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.

I was worried on a personal level because I wanted to be slightly taller than I am, ideally. But I've now accepted it. Basically, I came to the conclusion a while ago that you can either be really bitter about it or you can make loads of funny jokes.

The idea the actors are the most important people on a film set I think is very stupid. Actors are the most replaceable people there. There are literally millions of us. There's very few people that can operate a steady-cam. The numbers are a lot, lot fewer for that, you know?

I think any man who says he has never had an awkward moment with a girl, is a liar or he's delusional because he's sitting there thinking he is doing really well and the girl is thinking "Who is this man and why is he talking to me?"

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 was very much a product of the public-school system. There was only one other kid in my class who had parents not involved in the stock market or law.

The only thing I can think of is my favorite album at the moment by this guy called Father John Misty, and the album is called I Love You, Honeybear. It's just brilliant. It's the album I'm currently obsessed with. It is original, and the lyrics are fantastic and [it's] brilliant. So that's blowing me away.
