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.

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.

I get off on the interaction with people, and I love the chess of a movie and particularly - not only in preproduction or in production or postproduction - the behavioral chess. That is, learning and being humbled by and also teaching certain people certain things. I love that. As a producer, you have an opportunity to see the whole and bring people together.

The Jake Gyllenhaal workout planstarts with growing long, long hairgorgeous greasy locks and then washing every day.Wash, shampoo, then condition. Washing works the biceps and then the triceps by conditioning. And vigorously rubbing all of your body with soap really defines the abs and the pectoral muscles. And if you do squats while you're bathing - that's it!

I think it's more, at least at the time, a sense of abstraction. My mind doesn't really work in a way where there's a definitive sense of something. I go one way and then it opens up into a million different ideas, and somehow, when you look at the art, Buddhist art, or particularly Tibetan art, you know, it's a similar thing. All of a sudden there are a million lotus leaves and you're following one to the next and to another, and I related to that, and it felt simple and easy to me. And it made me feel smart.

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.

Romance is important, but to have a friend you can use as a mirror, who can give you an objective response, that's what's really important.
