I never get recognised here in London, which I like. Once a year, someone comes up to me and asks if I am 'so-and-so's niece' because they think they recognise me from somewhere. I like that.

I don't think you should ever damage other people for your art.

It doesn't matter what you feel - ultimately, it's what the audience feels. You can finish a scene and think to yourself, 'Oh, God. I was so deep in that moment,' and find it just didn't play. I don't know if I have very good radar about that or not.

People get married when they're 18 and spend their whole lives together. I think their greatest fear is that someone will see it as a fling because they were young and it didn't mean anything.

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 don't think I want to play title roles. I don't want to be the face on the poster. I don't want that pressure of having the success riding on my shoulders. I just want to play the most interesting parts. I actually think it's incredibly rare to get an interesting female character that is the lead in a film. Usually the character parts are so much more interesting to play.

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.

It was my dream for years... to train. Dominic [Cooper] went and he's doing alright. But some people don't go and do brilliantly. Although I think there are things I missed from not having trained. I think I'd be more confident on stage had I gone because I think it means you're equipped with better vocal training and things like that.

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.
