I have been known for almost 30 years to sort of do whatever comes my way. It's always been touch-and-go after each job finishes. I just like to be working.

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.

The key to acting has much more to do with listening than with talking.

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.

"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.

That's probably the biggest secret of acting: If the actor believes it themselves, they can make you believe it.

The director is the captain of the ship, without question. No matter what their talent or energy level is, everyone on the crew has all eyes on the captain. If they come in going, "I don't know. Maybe we'll do this. Maybe we'll do that," you've got 10 days to shoot and they don't care what you're doing.
