I feel like that [the role in Star Trek] is a prime example of, yeah, I got that role and it was awesome, because it changed a lot for me professionally, but then creatively, it became a whole other thing, with J.J. [Abrams] and Chris [Pine] and the people I got to know. Now I just feel like it's our jobs to be open and to keep moving stuff forward. I don't know what that means. This is the first time in a long time that I have no idea what's happening next. As scary as that is, and as anxiety-provoking as that can still be, it's also really exciting.

I found it was remarkable. It was so evocative. I feel like it captured the urgency and the chaos, but through the silence of it, through the slowness of it. That's what I loved the most about Citizenfour.

I met Glenn [ Greenwald] briefly in 2009. We were both guests on Real Time With Bill Maher. I was the show's guest and he was on the panel. But this was before the Snowden stuff happened. I didn't have the opportunity to meet him in preparation for the movie, unfortunately, for various reasons. But I was able to dive into the main articles he's written, and interviews with him, and just the function that the character serves in the movie, that was enough for me.

I would love to be a voice in this maelstrom of chaos and obsessive celebrity infatuation that says, 'Let's talk about something that matters'.

I would say auditioning was my real training ground. The technical aspects - like hitting marks and pacing yourself and preparing and dealing with the downtime - the first recurring role I had on 24 was probably the way I learned that stuff.

Who's to say what would have happened if I had trusted my instincts and moved to New York like I thought I would.

I think there's a tremendous sense of complacency in the LGBT community. AIDS has lost the edge of horror it possessed when it swept through the world in the '80s. Today's generation sees it more as something to live with and something to be much less fearful of. And that comes with a sense of, dare I say, laziness. We need to be really vigilant and open about the fact that these drugs are not to be taken to increase our ability to have recreational sex.
