Education is huge for me. I went to public school until I turned thirteen, and was lucky enough to afford college once I became successful as an actress. I cannot believe that quality education costs as much as it does in this country. Ghetto Film School is a remarkable public high school in New York City where students get to learn to express themselves through filmmaking, and have hands-on access to equipment.

I remember seeing Janet McTeer in A Doll's House. My grandmother took me and we had seats in the very back row, but her performance was so powerful - it was very accessible. I felt like I was much closer than I was.

I think women get caught up too much in having a plan - 'I'm going to get married at this age I'm going to have a kid at this age' - and then they just try to find a guy who will fit into that picture. I don't want my life to be based on that.

With film, so much is in the director's hands. Once something is cut together - unless you're in the editing room - you don't really remember what the alternatives are.

Bill Pullman is older than Aaron Eckhart - although I was older too - and the age difference changes the play. My perspective on those issues had changed a lot. Without going into nerdy details about that play, there was something that still stuck with me. I still had the same joy in that dialogue and David Mamet's rhythm in terms of his writing. I felt like there was still something to explore.

When Paul [Greengrass] was writing, he'd send me story ideas that he had. He was particularly interested in social movements and revolutions that had been happening all over the world, and how computers and the internet had helped those movements. He encouraged me to read a book about Anonymous, the hacker group called "white hat" hackers, meaning they're driven by ideology and social disruption as opposed to just greed.

Yoga has stopped me from destroying my joints after running. It slows me down. My brain and body can go into overdrive - yoga teaches me to focus on the moment and not get ahead of myself.
