I would never want to move to L.A.

Once you move away from home, it's never quite the same again. You expect everything to be just as you left it, and it never is. It's almost the first step into adulthood, realising you've got to make your own way.

Sometimes the director will want you to write about the character, sometimes he'll want you to live in the location that the character is from or something like that, but I don't usually make a lot of notes or anything like that.

I think that when you're an actress, you have to think about what kind of a role model you're going to be. I hope that I'm a good role model for young girls. I'm not going to, if people still want me in their movies, I don't want to be one of these girls who goes around partying every night and is in rehab. I don't want to do that.

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.

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.

I remember being on Atonement and it felt very right to be there. There was so much excitement every day. I remember very vividly how it felt to be a child on a film set, and that is actually really important to hold on to for as long as you continue to make films.
