My experience on 'Jarhead' was life changing.

I fooled around with Heath Ledger and Michelle Williams got pregnant.

I could draw ideas. I remember writing a paper for a seminar class. I remember writing a paper about - and this is going to sound really sort of pretentious, but that's where my mind was at the time - how acting and the performing artist can really be like a Bodhisattva, how they can communicate ultimately an idea in a way that can move and shift things. And that was wonderful. I didn't know many classes where I could try and relate the thing that I really loved and wanted to do into an intellectual idea, and that happened to be one of them.

We all develop relationships with each other based on our first relationships, and then how we experience them. But inevitably they are echoes of earlier on. In my belief.

As Uta Hagen would say, there's the representational actor and the presentational actor. My sister [Maggie Gyllenhaal] came up to me recently after she saw this movie, Southpaw, the movie I did, and she thought there was this exploration of that type of presentation, and a bit of representation as well, if I could be totally honest, where she was deeply moved.

Masculinity is, nowadays and generationally, confusing. What is honor, what is protection, what is being a man? It's evolving. But I believe having an open heart - and a strong mind to protect that - is the idea.

To me I just, I'm a geek when it comes to cinematographers . And when it comes to Robert and when it comes to someone like Roger Deakins who shot Prisoners and he shot Jarhead.
