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.

Heath [Ledger] would walk up to a horse and could like silence the horse. Just literally he'd be like, 'Shh. Shh.' And then he'd get on the horse. I'd be like, 'I'm going to get on you.' They'd be like, 'F - off!' I didn't really have that style.

Crazy people don't sit around wondering if they're nuts.

You can’t just lump things into two categories. Things aren’t that simple.

What world am I living in?' Aren't movies made to have something to say? Why make a movie if you don't have something to say? What are you doing it for? Are you doing it because you want to make a lot of money?

Being a star doesn't last. That's not what life should be about. It's a complete illusion that really has nothing to do with you. For me, finding out about life is the most important thing.

I remember Chris Cooper saying to me - I was doing October Sky with him - and he said, "You know, you're just yelling at me." He's like, "You're just yelling. You need to listen." We were in a fight, and you know, oh you'd get so excited as an actor, you're like, "We have a fight, oh, I get to get mad." And he just said, "You need to listen." And I started listening - and then all of a sudden where I was listening was where, I don't know, anger became something else.
