Acting is a business and a political act and a craft, but I also feel like it's a service - specifically, for a military audience.

The Marine Corps is some of the best acting training you could have. Having that responsibility for people's lives, suddenly time becomes a really valuable commodity and you want to make the most of it. And for acting, you just have to do the work, just keep doing it.

Girls' feels very active and stirring a conversation and controversial, and you can't really ask for more as an actor.

In the military, you learn the essence of people. You see so many examples of self-sacrifice and moral courage. In the rest of life you don't get that many opportunities to be sure of your friends.

The only thing I know that makes me feel comfortable is to know as much as I can. Not like what the shots are going to be, but knowing enough about my character that I can forget those things. And more specifically, my lines. I have to know my lines. I have to know something really well, so I can forget it when we're doing it. And there is comfort in knowing, "Okay, there's not another stone that I could have overturned."

What is important is to maintain integrity of the story, of the character, of the movie, even if it's a big production.

It's hard to kill that father-son bond.
