I've been looking for ways to audition more, because it also keeps me sharp and keeps my ambition at its firm edge. That's something that I'm actively engaged in conversations about now with my reps: What's out there that I can really either put myself on tape for, or meet with the director for and read for? How do we do that? We're now at the end of the Star Trek reboot trilogies and whether we are going to do another movie remains to be seen, and so I feel like I'm at the end of this cycle that began with me coming out of school and auditioning and building my way up.

I remember having to hit a mark and having no idea how to do it, real childlike stuff, because Carnegie Mellon didn't do an extensive job preparing us for film and television. It was very much a theater program. That was my first job. It was cool. I was glad it was.

I don't really approach a character as to whether or not it's good or bad. I just approach a character as to where it lives in me.

It certainly woke me up to how vulnerable we all are. I think I was much more cavalier about it before I started working on the movie [Edward Snowden], and then the more I read the documents themselves and saw just how sweeping and indiscriminate the intrusions into our privacy have been, it made me more aware.

The advancement of technology has probably guided us more than anything else in one direction or another. I don't know, it's hard to say. We're so much more connected, but we've never been more fractured as a culture.

Zoe Saldana is such an angel. She’s got such an openness and vulnerability on camera and yet such great strength. She can kick ass with the best of them, but then she can soften and open up in a way that is magnetizing whether you’re watching her on set or on screen – she’s got a real power to her. I love her; we’ve known each other for years and it’s great to come back to that kind of familiarity, especially when you’re working with such intimacy.

While we were shooting the movie, we shot in the actual hotel in Hong Kong where it all went down, the Mira Hotel. Laura Poitras was coming to Hong Kong to do a screening of Citizenfour, and she ended up staying at the Mira Hotel. It was her first time back in Hong Kong, and I ran into her in the elevator. Literally I had just finished shooting one day, and I came back to the hotel and she was in the elevator.
