I'm an optimist by nature, myself, I think.

The ratings thing is the real issue. It really hurts movies. For example, in Redbelt, I smoked. The whole plot of my character was based on the fact that I was a smoker. And then they discovered that just by having someone smoking in the movie, it immediately makes the rating an R. So they had to cut out every shot where I had a cigarette in my hand and it totally affected the performance. That was very frustrating to David Mamet as well. I can remember him saying, "It's a nightmare."

I must have been a really pretentious little girl.

My take on people and on the characters I play in Transsiberian, the role you're looking for, is that everybody is more than one thing. We're many things, all of us, and there are times when we are capable of great levity and jolliness and then there are times when the opposite is true.

You are exposing yourself all the time as an actor. There's the risk of being thought of as bad or boring or unattractive.

You do the one film that you think is terrible, but it's a big studio film and you hope you'll get another job because of it, because blah blah blah, whatever it is. You know that you hate it, you just couldn't care less if it got made because it's not something in a million years you'd go and see yourself. And it ends up being shite and you just knew it was shite to begin with, and it doesn't do you any favors at all if someone thought you were in another shite film. So I decided it doesn't get me anywhere being cynical. It's not that I want to be.

It's very difficult to find the time or the money for people to organize rehearsals for some movies. It staggers me how little preparation often goes into these scenes which are difficult and complicated. You think, "God, it's crazy. I've never met this person before and here I am having to work at how to do a whole performance on the set." It was great to have a few days of just talking to Michael [Caine] and Daniel [Barber] and thinking about the characters and the relationship between them before we started shooting.
