When I walk into a screening, I'm nervous in a different way than I am as an actor. But the response is ultimately I know how I feel about it and that's what matters to me the most.

I don't think I'm sharp enough to not prepare and come on set and kill it.

Heath [Ledger] was always somebody who I admired.He was way beyond his years as a human, in a way.

I think I'm generally - fear, fear is very still, so in terms of that kind of fear - there's so many different kinds of fear, but fear is something, particularly in movies, that's interesting, because it's created by the film maker, that was created by David Fincher, that's why he's brilliant.

It's one of the most beautiful scripts [Brokeback Mountain] I've ever read, and it was Ang Lee, and at the time Heath [Ledger] was a friend of mine - before we even shot the movie - and always sort of alluring to me.

You run your plays, you know your plays, you study your plays, you study the other team, you do as much as you can, you go to practice, you get in shape, you do what you need to do, and then by the time you get to the game, you know your plays, but they have to feel like they're in your bones. That has to be an unconscious thing, it cannot be conscious. That is everything to me.

My experience on 'Jarhead' was life changing.
