It was actually pretty cool to be in Pittsburgh for those four years. I moved into the dorms and had a pretty normal college experience, even though it was in my hometown. I really thrived there. I feel like it really suited me and served me well in terms of how I grew up there.

I think the goal is always to go deeper within myself, and accept myself on deeper levels and to know myself on deeper levels. Whether or not I look for roles that are going to do that for me, I certainly look for the ways in which the roles I get can do that for 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 razor-sharp line of division that exists between political ideologies in our own country in the United States, I think it's clear that these movements are forming - and one is more forward thinking and more embracing and more inclusive. The other is less tolerant and more judgemental and more fear-driven and fear-based. I think, you know, over the next generation, we're going to see which way we turn as a civilisation.

Leonard [Nimoy] was such a teacher for me. He was one of the most fully realized human beings I have ever known on every level - in his personal life with his personal relationships and his love for his wife and his evolution with his family. Then as an artist, as an actor, as a writer, as a poet, and as a photographer. He never stopped.

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.

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.
