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

Even the former Attorney General of the United States Eric Holder has come out to say that he believed that [Edward] Snowden performed a public service, and I couldn't agree more.

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

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.

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.

I just find that there's something about looking back on interviews, whether for purposes of remembering what I said about something or if it's for posterity when I'm 75.

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.
