I think mystery is kind of great. I don't know anything about Bette Davis or Katharine Hepburn or Ava Gardner - not really - and I like that. I love watching their movies because they're my personal movie stars. I don't know what they eat and who their trainer is.

I think London's sexy because it's so full of eccentrics.

I'm not confident around compliments or being celebrated, and I'm not comfortable with the thought of envy, which some people thrive on.

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

Well, I'm not at all like the tough, sexy femme fatale in Confidence but it's fun to play people who're really different from you, from different cultures and places. I suppose I'm a bit quieter than most of the people I play.

L.A. makes you feel ugly.

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.
