Good people can do terrible things, and that's what life is all about, the complexities and grey areas. And often characters aren't written that way in movies, especially characters for women. So you end up being either one thing or the other.

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.

The harder the circumstances under which you're making a movie, generally the better the friends you make. You're far away from home and so you're kind of lonely, and you end up all gravitating towards each other and the bar every night. It tends to be inversely proportionate to the comfort level on the movie, how close you become to everybody.

I had watched 'Alfie,' but I didn't consider it a prerequisite. Michael Caine was just extremely fabulous. He's one of the most professional actors I've ever worked with. I guess after a lifetime of doing it, you know what you're doing. He's incredibly uncomplaining, undemanding.

It's quite frightening; the business of trying to be funny is very hairy. In comedy, the potential for humiliation is huge. Trying to be funny and failing is about the most embarrassing thing you can do.

It's dangerous talking about yourself too much because you find yourself talking in sound bites.

I have to say that, though it sounds so superficial, the accent really does help. I like having accents preparing for a part.
