Warren [Beatty] loves to talk about his experiences with [Elia] Kazan.

With 'Hail, Caesar!' it was about all the skill sets I had to learn, but each movie requires a different way of working. You're a piece in a new world, and there is always a difficult part within that world. For me, it's not consistent from movie-to-movie, each film has a central challenge.

You get bummed out, and then you go, "Oh! Now I get to go buy a present for myself." That kind of helps.

That is sort of the eternal question for people who go to Hollywood...what will be the straw that breaks the camel's back, and forces you to think about doing something else? When do you throw in the towel?

[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.

The actors at that time had to learn all that stuff, it wasn't just hyperbole. What was appealing to me about being an actor at that time is that there was a home base, with job security. You were employed on a regular basis, and you had to sometimes do things you didn't want to do, but it was there. I also liked Hobie Doyle positivity.

Just getting to talk to that person [Woody Allen ] in real life was pretty wild.
