When I don't understand things, I become passionate to understand.

I was a punk rocker when I was a teenager. I wanted to look like Nancy Spungen. I had dyed blonde hair and lots of piercings.

With most movies I've done before, I've done a lot of preparation. I've known about them long before [shooting], and I've prepped and changed my body and done research, and all the things you could imagine.

I hate when you see a film and after one scene you know what's going to happen and you can predict the whole story.

I'm interested in people's darker side, the ones that aren't easy and well balanced. The cracks.

I'm obsessed with the human psyche. I want to understand. I want to ask myself if I have it inside me.

I can't see any value in being a celebrity, famous for being famous.
