It's not exactly an interview that's going on [in documentary]. I guess we do ask Edward Snowden some questions and we're recording him answering them and so on like that.

Being an actor on a movie set is like going to the playground at recess.

I was really not familiar at all with Edward Snowden. I like to get that right out of the way and really learned most of what I know from Oliver's [Stones] script.

"I'm going to show you I haven't given you permission because clearly you're not grown up enough to understand that, not having given you permission, you can't just come look in my house." And I won't know if they're coming and looking or not... so I put a piece of tape over it.

You can't really gauge the difficulties of television. There's difficulties and joys that happen with an amazing, great team, when one is working.

I'm very old-school. I like a director to direct me. I like to be the actor. I'm not particularly fond of the hybrid writer-director, or actor-director. Writers, directors, actors are all such very different people. I think it's unusual that two of those people are in one human.

I definitely consider myself a Method actor, because of my training. I might dispute what people consider a Method actor to be. For my money, a Method actor is an actor who has a technique. That has a method. And not one method, but whatever might be required. So a Method actor is always learning.
