We live in a celebrity-obsessed society.

I act because I have to, because I need to find out whether I can do it or not - that's what drives me and excites me and lights me up.

Women do well in their thirties. They put their bags down and say, 'This is who I am - like it or lump it.' There is a more relaxed quality, which I like.

I've no wish to appear in celebrity magazines.

I'm not temperamentally into high comedy. I'm not a Noel Coward kind of girl.

I don't like the word celebrity. If I become a good actress and be in movies where I'm expected to be a good actress, who is recognised, that's different to being what I consider to be a celebrity. My job is an actor and that's what I'm passionate about and adore. It's a privilege to be able to do this job for a living.

My family believe you should never be flashy about anything. Maybe that handicapped me a little bit, that extreme humility.
