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.

When you idolise someone, or you hold someone in such high regard, you just want them to be everything that you think there are - and when they are it's just lovely.

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 want to be in 'Glee,' but I'm told I'm not famous enough to be a cameo yet.

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.

I grew up with an older brother, so I'm pretty good at being bashed around.

You can spend an entire day walking around in New York, whereas in L.A., it always ends at some point because you have to find a way to get home.
