I love supporting emerging voices, and new writers and directors. I love engaging an audience in a way that doesn't have to involve me, personally, and yet still generates an experience for groups of people.

I recognized that I had a window of opportunity that had opened because of my exposure as an actor.

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.

The situation they [journalists and Edward Snowden] were in was incredibly heightened. The stakes were high. There was a lot of pressure, a lot of tension, a lot of sense of claustrophobic, clandestine energy that I think was exhilarating for us to explore and recreate. We were fortunate to shoot a fair amount of our stuff at the actual hotel where it all happened in Hong Kong. That added another element of very similitude to the situation, so I feel like it was exciting.

It's funny that you [Zachary Quinto] did a monologue from Pounding Nails in the Floor With My Forehead. I did the same thing for my university when I went to USC.

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.

What we do with the information now is up to us, but certainly I have a lot of respect for the courage and integrity that was required for [Edard Snowden] to take that action.
