When I am on set or rehearsing for the play, the only thing I can talk about is the work I'm doing. In that way, I home in on what I am doing at the time. So maybe I am a terrible multitasker.

The majority of teenagers don't even make eye contact with people, even people of the same age.

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 saw 'Clueless' probably when I was about 8 or 9 years old. And, I had certain films that I would fall asleep so it was 'Clueless' for quite a long time, and I used to just watch it every single night and knew every single line, every single quote.

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.

There's so many modern films where the fans take one side or the other. I'm hoping this isn't going to be like that; I'm hoping it isn't that kind of film at all. What I would love for the audience to take from it is to understand why she was so stuck in the middle and confused.

I'm a huge Wes Anderson fan. I literally love every single film. He hasn't made a bad film; I've seen every single one. They've all been brilliant, from 'Bottle Rocket' up to 'Moonrise Kingdom,' they've all been wonderful.
