We grew up with a camera in front of us.

The majority of teenagers don't even make eye contact with people, even people of the same age.

I've always been quite an active person especially when I was younger. When I was in primary school, I used to play lots of sports. I was a sprinter and I did basketball and swimming and Gaelic football and things like that. So I always thought, I guess, that it would be fun to incorporate that much physical activity and work into a dramatic piece.

I saw 'Clueless' probably when I was about 8 or 9 years old. And, I had certain films that I would fall asleep so it was 'Clueless' for quite a long time, and I used to just watch it every single night and knew every single line, every single quote.

I wouldn't go down the route of having an assistant. I don't want to be like that. I want to be normal.

I will always have a child in me. That is what Pete Jackson has got, what a lot of the directors I have worked with have. It is about knowing how to have fun and that is something I always want to hold on to.

When I was younger, I would mess about and have a laugh with everyone. I was doing Atonement when I was about 12, and as we went to do this very serious scene, the director Joe [Wright] came up to me ... I'd been giggling right up to the beginning of the take. And he came up to me and said, "Okay, you need to be serious now." I completely idolized him.
