I remember calling and asking, because I had a few lines that were like, "How could the character have done this?" and I hadn't read the part of the script that said what she [ Cate Blanchett] did, so they put me on the phone with Woody... Allen. I don't know if I could really say "Woody."

I had the opportunity to learn more about what life is like for a soldier [in The Yellow Birds].

That's a lot more legitimate than the retail therapy I do.

That was cool, because they've all [ George Clooney and Josh Brolin and Scarlett Johansson] worked with the Coens. They were much more at ease with them at the outset, and they were all kind of familiar with the shorthand that the Coens had.

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?

I've always felt whatever the opposite of disillusioned is. I guess illusioned with movies and with people in movies and things like that. It's all exciting to me.

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.
