Good people can do terrible things, and that's what life is all about, the complexities and grey areas. And often characters aren't written that way in movies, especially characters for women. So you end up being either one thing or the other.

My dad had this philosophy that if you tell children they're beautiful and wonderful then they believe it, and they will be. So I never thought I was unattractive. But I was never one of the girls at school who had lots of boyfriends.

I've only half-admitted I'm a professional. I know I am, I've paid my dues, but one of the things I could do better when I'm acting is to really be rigorous and to think I know how to do it. To use my brain.

It's very difficult to find the time or the money for people to organize rehearsals for some movies. It staggers me how little preparation often goes into these scenes which are difficult and complicated. You think, "God, it's crazy. I've never met this person before and here I am having to work at how to do a whole performance on the set." It was great to have a few days of just talking to Michael [Caine] and Daniel [Barber] and thinking about the characters and the relationship between them before we started shooting.

Every time you start a new job, you're starting from the beginning again and it's terrifying. And you feel like you're going to be fired and told to go home and never to darken the doors of these people ever again.

You do the one film that you think is terrible, but it's a big studio film and you hope you'll get another job because of it, because blah blah blah, whatever it is. You know that you hate it, you just couldn't care less if it got made because it's not something in a million years you'd go and see yourself. And it ends up being shite and you just knew it was shite to begin with, and it doesn't do you any favors at all if someone thought you were in another shite film. So I decided it doesn't get me anywhere being cynical. It's not that I want to be.

There's something helpful about the fast pace of a TV set where everything has to be finished by the end of the week. You have to finish the episode; it doesn't matter how long you have to go on Friday night, but you have to get it done.
