I'm a harsh critic, you know? I am.

I think also what's interesting is that Maggie [Gyllenhaal] knows how much the choices that I make reflect what's going on in my life. Admittedly, probably, as my sister, and as someone who loves me - like, she can't wait to see become a father.

Working with Robert, Robert [Elswit] is a storyteller. He's not a cinematographer, he's a storyteller. And to me, that's the graduation I hope to get to in my profession. That I'm not just an actor, I'm a storyteller. And I think that takes a long time in, when you have one job on a movie set. Makeup artists, actor, whatever. To graduate from just that to storyteller.

Peter Sarsgaard, he's an extraordinary actor, and I would say that Peter has really brought into my life and my sister's life a sense of presence as an actor that I never really understood or knew about until I met him. They've been together for a very long time, and he introduced me to the idea of the presentation.

I was brought up, and my sister too, with two people who were always saying, "What you do is really nowhere near as important as the things that are going on in the world, and if your work needs to reflect that, or you want it to, then you need to strive for a certain type of excellence."

Chris Cooper once told me to never have any regrets. After Chris said that to me, I walk into every scene thinking, 'exhaust every possibility.' Once you get to a certain place, it's like you just deliver everything you've got. Don't have any regrets. It pops up in my mind over and over and over again.

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.
