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 appreciate the written word and spoken word more, but Atonement sort of established so much of me. It was a character that didn't really speak, and I found that a lot of the roles I was gravitating toward after that were kind of nonverbal.

I love cleaning. I love mopping the floor. If you need your floor mopped, I'm there.

I listen to everything. I love The Chemical Brothers.

One of the things that would steer me away from a franchise is that I'm playing the same character all the time and I wouldn't want to be known for that.

Joe Wright was almost like a teacher, to be firm with me, that really stuck with me. And that helped me as I've gotten older.

I don't mind doing the whole red carpet thing when I have to when it comes to publicizing a movie. But besides that, I don't like those kinds of things at all. Celebrity status is not really something that appeals to me.
