It's funny that you can murder someone horribly and graphically and disturbingly in a horror film, and it's not an NC-17, but if you put a naked man on screen, everyone freaks out.

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

I did The Seagull, the Chekhov play, on Broadway, a couple of years ago, and I had done it in London, and I became completely obsessed with the character, Nina, that I played in that. She's an actress. I couldn't find a play after that, that I wanted to do, because I couldn't think of doing anything else. Every part is a disappointment, once you've done that part.

I've never been obsessed with celebrity or star-struck or anything. I met Penelope Cruz when we were in Toronto, who I think is a goddess and an unbelievable actress, and she introduced herself. As she walked away from the table I had to take a deep breath, which was strange because I've never had that with anyone.

I was quite straight-laced. I was quite academic until I was about 14 and then I went to boarding school where I had the opportunity to continue to be very academic, but got less interested in it and became more involved in acting. And then when I was applying for universities I used a couple of places on my UCAS form to apply for drama school without telling anyone... but didn't get into drama school. But that was the most rebellious thing I did.

From Wall Street to Drive was almost a year, when I didn't do anything 'cause there was just nothing that was significantly different from the things I'd done before. There was just nothing to explore.

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.
