I kind of don't believe in actors directing themselves. Obviously some people have done it well, but I don't see how I could. It's funny that you ask, because I've just been thinking that maybe I'd rather direct The Bell Jar than act in it. It's a huge leap to go from a short to a feature, so I'm tentative - I'm like, Well, that's just so triple-type-A personality of you.

It was nice that there [ in the Bourne Ultimatum ] was a reference to the relationship . It's very subtle - it's actually without dialogue. I do think it's powerful even without words.

Actors can write and produce too. Then when I was working on Jason Bourne­ - having had that experience - instead of going back to my trailer and being separate from everyone else, I would sit behind the monitor and watch Paul Greengrass work and be much more included in the process. That was new for me and really enriching.

I do think that the more takes you have the more opportunity to experiment [but] at a certain point, there are diminishing returns. There's only so much variety you offer.

I always loved how people like Jon Voight and Laurence Olivier shocked you every time they came on-screen. They were so different each time. That's what I hope to do with acting - be the chameleon and not get stuck in a type.

I think that ultimately I just have to be myself. You know, I don't do anything that outlandish anyway.

My regular school didn't know what to do with me!
