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.

I did a run of a play over the summer in a really tiny theater in New York and that was rejuvenating for me. I directed a short series for Hulu called Paloma and being in an editing room, I learned a lot about acting.

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.

I'm going to Columbia University but I'm trying to keep that low-profile because I don't want weird people following me there. I want the experience of normal college life.

It's not my job to critique the writing. I'm there to serve it. I had to figure out a way to make it work.

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.

My regular school didn't know what to do with me!
