Vampire teeth really aren't very efficient, are they? It looks very messy. I'm not sure it's the best way to get a pint off anyone.

If you don't have eyebrows, you don't really have a face.

Ivo van Hove is directing The Crucible, and rehearses in quite an unusual way. We started rehearsals last week and dived straight into the first act, like, five minutes after we all turned up. No warm-ups. We were very intensely immersed in that whole world on day one. It was quite surreal because I've never done any theater before.

I really want to go to college.

I don't look at rushes, or I don't go to the dailies. I don't even really look at playback unless it's an action scene or a move that I need to do better, something like that.

When I was younger, I would mess about and have a laugh with everyone. I was doing Atonement when I was about 12, and as we went to do this very serious scene, the director Joe [Wright] came up to me ... I'd been giggling right up to the beginning of the take. And he came up to me and said, "Okay, you need to be serious now." I completely idolized him.

I will always have a child in me. That is what Pete Jackson has got, what a lot of the directors I have worked with have. It is about knowing how to have fun and that is something I always want to hold on to.
