I'm trying to make myself sound better.

I did my first film with Francis Ford Copploa which spoiled the hell out of me.

[The Yellow Birds] is based on a novel written by Kevin Powers, who is an Iraq War vet. I play a soldier who promises my friend's mother I'm going to keep him alive. But when we go overseas to Iraq, he gets killed. It's about what happened to him, my reckoning and dealing with that as I return home from the war.

I've definitely been spoilt. Every movie I've done, it's always the same criteria: finding a great story, and finding a great part to play.

Let's say [Warren Beatty] wants you to speak louder in a scene. He won't stop playing the role and say to you as a director, "Will you speak louder on the next take?" He'll say it as Howard Hughes: "I can't totally hear you. Why don't you speak up a little bit?" To kind of keep this rhythm going.

Same with the Coen brothers and Warren [Beatty]. And then slowly you get to know each one of them as a person, and that becomes a kind of separate entity, where you just know the human being.

I'd never worked with an actor-director before [Warren Beatty].
