I am frivolous. But sometimes, that's the problem of my Christian education, when I know I've been frivolous, and I know I have to do it, then I feel guilty.

I'm afraid of being too sure, to just deliver. I think that's the biggest danger for actors - after a certain time, when you're known and recognised, people expect you to do what you're supposed to do, and there's almost no more criticism and that's very dangerous.

People who know me know I'm strong, but I'm vulnerable.

I don't live that much with the character. I find it hard enough having to spend so many hours with the character during the day.

But I never gave up personal things to work, never.

What I do is I come in the morning and get involved in the character, but I'm always very pleased to leave it at night and have my life.

Being an actress is a very physical thing. If I didn't look the way I looked, I would never have started in films.
