With a group of people, a troupe of actors in the theater, you go out on tour, and you're like a traveling circus. It's very sociable, and there's a real community, and it's very intense, and then you may never see them again. That was very appealing. I mean, it wasn't consciously appealing, but I think a lot of actors like that.

I always do my interviews face to face.

I think if you ask the audience to like you, it's all over.

Film is such a director's medium; you're really in their hands in terms of the real storytelling. As an actor, you can give a performance moment to moment and some of your takes will be used and some of them won't. I think there are great films you can make with bad performances, and vice versa. There are all combinations of those things. It's really down to the director what happens, I think, so that's why it's really good to work with very talented, bold directors.

The most interesting characters are those you're drawn to, then repelled by, and then come to understand. All that tension - I live that. But I don't plan the tension. It's just something that should happen.

I just kind of muddled through in my 20s. I did whatever I got offered, to be honest, to pay the bills. I didn't really know what I was doing. There are some actors in their 20s who are very sure. I wasn't very sure what I was doing. I feel like I've only really just got going.

Most of the time we do nothing, myself included, I think the lesson I learned from [playing humanitarian Tessa in The Constant Gardner] is that a lot of drops make up an ocean. If people would stand up and say what they believe in maybe we can make a difference. Helping one person is better than nothing. Just do something.
