I don't really think about roles - "dream roles." It's always about who's gonna be the person on the screen or who's gonna be the person on the stage and who's gonna direct it and put it all together.

When you do bigger jobs there's more attention and when you film in New York you get loads of paparazzi everywhere. It affects your work because you're trying to think about the person you're acting with and you've got 20 other lenses taking pictures of you at the same time, and it throws you.

People always say, "You played such a strong character." I remember someone said that to me when I played a role in Shame, and she was a suicidal mess. I said, "She's not strong at all; she's incredibly weak." But "strong" to people means "real." It means you believe that's a person who exists, as opposed to some two-dimensional depiction of women.

I want to play the fake child on 'To Catch A Predator.' No, wait! I want to play the Leaf Man!

Sex addiction is a subject that should be discussed

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.

I wanted to be in a Baz Luhrmann film. It's just extraordinary. He's so amazing at what he does. He makes the most incredible films.
