I listen to everything. I love The Chemical Brothers.

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.

For me, clothes are about individuality. When I wear things that are different and it works, it makes me feel good.

The written word can be powerful and beautiful - but films transport us to another place in a way that even the most evocative words never can.

I like books that are exciting and that make you think about things, as well. I like things that have a twist - like 'Atonement,' which I haven't read obviously, as I'm a bit young.

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.

Everyone thinks I'm ethereal. But I'm not like that, you know. I'm not ethereal. Well, I might have a little bit of that quality to me, that 'old soul' thing, but I'm not ethereal.
