I don't think I had any idea at the time how to work with someone as masterful as he is. And I don't think at the time I really understood what was happening. I think I was in a space where I was like: there are all these things. I was shooting all these takes with David, and I was just confused, as a person, and as an actor feeling a little too big for my britches and that this thing was happening and then also not having enough skill yet, and technique to know exactly where I was, and know about the character.

I know exactly what that movie's [Brokeback mountain] about. I can't define it; it doesn't tie up in a perfect bow. But it's about adolescence. It's about what it feels like - this isn't meant as a criticism, but like things I didn't relate to, which were high school movies. Where I'd watch it and I'd be like, "Well, am I like the kid that nobody likes? Or am I like the person who everybody [likes]?" I couldn't [tell]. I was like quantifying, putting me in a box. "This is my personality at that age" and "I'm this kind of person" just felt like bullshit to me.

I have an overactive brain, and as a result of that, I can really get in my own mind. So I like to try and exercise it to the point of exhaustion.

In that way, as an actor in particular, you're powerless. And so in that way as an actor in particular you can't make mistakes.

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?

I think that we all have within us the potential for almost anything. If we play close attention to our lives, then we can get at it somehow.

To me Donnie Darko was about adolescence. And about how, as soon as you start to grow up and you sort of move out into the world, you realize everything is so trippy. That anything can be anything.
