It's a lot of working out, you know, and you don't get to eat all the things you wanna eat.

You have to really make sure that every moment means something, and that every moment, there's a purpose for it. And then you have to blend it all together without it looking like you're really focusing on it. That, to me, was the magic trick that was most difficult for the film [Buried].

When I was younger, I was reticent to be vulnerable on camera and everything I was doing was just a really finely honed defense mechanism from when I was a kid, and I was now using this to make a living on camera.

I never took acting classes, but I knew I could do it based on the skill with which I lied to my parents on a regular basis!

I don't like seeing the stuff that's not polished. It's harder for me to step away from it and watch that.

It's just that... working on Green Lantern, I saw how difficult it is to make that concept palatable, and how confused it all can be when you don't really know exactly where you're going with it or you don't really know how to access that world properly - that world comic book fans have been accessing for decades and falling in love with.

I think that people see that Sandra Bullock has an ability to laugh at herself and you just don't find that too often.
