As an actress, it's part of your job to be able to imagine just about anything - even if it's not within your personal experience.

I love the way girls in London dress; it's so different to the American 'blow-dry and immaculate grooming' thing.

The Pagan model of religion because, in the Pagan model, there were lots and lots of Gods and Goddesses. They were all incredibly beautiful and there were statues of them everywhere, which is the equivalent of magazines, or whatever, today. And they were fallible, which is different from being mono-, you know, Jewish or Islam (where) you have the infallible, monotheistic God.

I don't judge the character at all. It's a bit like being someone's defense lawyer - you have to believe in their innocence in order to defend them.

The bond between mother and baby is so interesting. Women have been giving birth since the beginning of time, but when it happens to you it feels like a miracle.

Normally, I would do research. For The Constant Gardener, I played an activist, so I went to meet activists. You can find them dotted around. But with The Brothers Bloom, I couldn't meet a nutty heiress who lived in a bubble in a mansion. There was no one to meet. So this was just an active imagining, a daydream.

The thing about acting is even if you get technically more skilled at what you do, every time you begin a film or a play you're terrified. You don't know if you're going to pull it off. Every film and every story has its own set of challenges. I've never felt like, oh yeah, that's it, nailed it! You can never sit and rest. That's why it's such an exciting job. It's beginning again every time you begin again. New story, new character, new place, new time, new director. It's like moving to a different planet and trying to figure out how to live there.
