I haven't only been offered Hasidic roles.

I was offered more work after the Oscar. When I was younger, I would take whatever I was offered because it was money and work and experience. In a way, choosing is the hard part. I know that's a luxury problem, but it's true. I try to go where passion takes me.

I was advised by an American agent when I was about 19 to change my surname.

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.

I go and see music all the time.

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.

Often Hollywood crews go into third world countries and I don't believe they behave well.
