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

I probably dreamt about running off to America or something when I was 16 because it just seemed like I was studying algebra and going, 'What am I going to use this for?

I love New York - maybe more than Los Angeles or London. I think I'm happiest in New York.

It Girl' is such a weird term. It implies I go to parties and drink champagne.

I've always been quite careful about what I wanted to do. I've just never wanted to revisit old ground or do something that's easy. I want to do something that I would look at and go, "I don't know what to do!" The most exciting thing is when you're a bit scared, so I'm looking to find something that's really terrifying.

I wanted to be a musical theatre actress - I wanted to play Sally Bowles, forever and ever always.

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.
