As I get older, my skin shows more of how I am feeling, like a mirror. If I am stressed, or not getting enough sleep, I see it in my face right away.

I want the chance to play very different characters, and I've always wanted to do more films.

I always play girls who are quite traumatised, or a plain girl, but I'm happy with that.

My agent asked if I fancied Robin Hood and I thought: 'Yeah, why not?' I hadn't watched it, to be honest, but I'd seen bits and knew it was really popular Saturday family viewing with heaps of action. I thought it would be great fun. I was up for a good old play-fighting and the scripts were terrifically exciting.

It's nice to bring the changes with everything you do. As an actor, that's what you want to do, all the time.

I have to admit, I go through phases of being good and bad. When I'm being good, I go to the gym three to four times a week. I do much better in a class with other people. I like aerobics and circuit training.
