I feared disappointing my father more than anything in the world.

I know there are actors we all want to beat up a little. I think it's important to do whatever it takes, and whatever it takes sometimes involves some physical or mental discipline. There's a lot at stake.

Marathon running, for me, was the most controlled test of mettle that I could ever think of. It's you against Darwin.

I noticed while working on Green Lantern that the actor - albeit forefront in the film, obviously, and the key focus for the audience - is kind of the smallest cog in the machine when you're shooting.

I have a discipline that has served me very well in my career and in my personal life... and that's gotten stronger as I've gotten older. I've always felt if I don't just have a natural knack for it, I will just out-discipline the competition if I have to -- work harder than anybody else.

When I do comedy, my brain sort of locks up in the infinite possibilities. That's where I get sort of lost. I think, "Oh, there are six other jokes that we could say here!" I feel more at home with drama.

If you have a dishonest moment, you're going to lose the audience. So I had to not only light myself in the scenes.
