Sometimes when you walk onto a set, there are very clear delineations. The crew don't talk to the actors and I hate all that. Everyone is the same to me and I always treat everyone in the same way.

I'm quadracontinental. I've got a life in London, New York, L.A. and Hawaii.

All I do is watch TV and films, and when I'm not doing that, I'm making them. I need a hobby!

You know I hate watching myself on TV, I know a lot of actors say that, but it's true for me.

I'm not Irish. Just because I have red hair doesn't mean I'm a lucky charm, you know?

When I first got the job, I was told nothing about my character. She's an anthropologist and she's tough, she's a female Indiana Jones. That's what I went into [Lost] knowing.

I never did any sports at school. It wasn't until I moved to America, to New York, when I was about 20 that I actually thought that if I wanted to be an actress I might have to start working out.
