Coming from dance, I feel acting is - I'm not going to say easy, because it's not. But the dance world is more hard-core.

I think that I burnt myself out a little bit with my dancing because I did so much of it. I was exhausted so thought that I would try a different kind of performance and expression and acting seemed like a close fit; it was similar in some ways to dancing. My mum showed me some really good films and so I became interested in films and acting.

With dance, you learn to channel nerves into energy, excited energy.

I didn't shoot any guns then or when we did the scene with Uncle Charlie [Matthew Goode] and Evie [Nicole Kidman] in the hall. I sort of pressed the button but there were no blanks or anything in there because I think it was always going to cut.

Fame is useful in certain ways, because it helps you get more roles.

Doing an accent removes you from yourself and reminds you, every instant, that you're playing a part.

Ballet has really helped me in every acting role. You have to be very disciplined, you have to be able to control your nerves and perform under pressure, and all those things you have to use in acting when you're on film or going for an audition.
