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.

You know, in America, Christian fundamentalism vs. science. You know, be it teaching Darwinian evolutionary theory or stem cell res- You know, the whole thing, and then the issue of women being educated in Middle Eastern - I mean, it just seems so contemporary. In terms of spirituality, it's interesting because I actually think (her character in Agora) Hypatia is very spiritual.

Botox should be banned for actors, as steroids are for sportsmen. Acting is all about expression; why would you want to iron out a frown?

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.

I go and see music all the time.

Because I think in order to get famous you have to be known for something. Like 'You're the romantic comedy girl' or 'You're the Oscar-winning whatever girl.'

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.
