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.

You have this certain about of responsibility to play a fictitious character and you have a script that's guiding you and the other information of the custom department's choices, and the set department, "Where are you," and all those other pieces of information but you have to cull from your imagination the answer to all the unasked questions. And with a real person, there's someone to get that information from, perhaps.

I don't tend to use technology all that much. Of course, I can't avoid it - it's called the telephone nowadays. And I do a certain amount of email, work-related primarily, on it. But I don't do a lot of looking for things online.

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.

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'm a little bit of a glutton for punishment, especially when it comes to work. I don't mind a bit of suffering. I think it's in suffering that we realize our best selves.

I think I understand the line between my job and the director's. I have no interest in directing. Not my movie, not your movie, nobody's movie.
