I've always played characters that were younger than myself.

I don't wear a bikini on the beach. I walk around my house in pyjamas. I haven't seen myself naked in the mirror for probably a decade. I'm very prudish.

I remember in 'Pride and Prejudice' I had to do a scene where I broke down. And before we filmed I spent like three hours imagining my mum's funeral. Actually, she's very much alive, happy and healthy. It was really horrible.

Sex addiction is a subject that should be discussed

There's always the things that you think are going to be tough. I've been nude once, and I was like, "Oh, that's going to be a nightmare," and actually that was fine.

I never sit in a cinema and go, "Ah! I want to be in that film!"

I'd like to do a play, but I can't find the right thing. I don't want it to be a starring role. I just want to play a really interesting character.
