On 'Into The Wild' I spent months risking my life and on 'Speed Racer' I spent 60 days acting in front of a green screen. No danger to my physical self, but I sure had to use my imagination.

I'm a very, very conservative driver.

Artistic ambition is important. And it seems it would be a great time to do some theatre, like a new extreme.

How much cooler was Oz than seeing the little dude behind the curtain?

The willingness to keep learning is, I think, the most important thing about trying to be good at anything. You never want to stop learning.

I've realized that what you think of when you make a 'big movie,' if it's actually a green screen movie, it's like doing independent New York theater because you don't have any backgrounds or props. So it's kind of like making the lowest budgeted film you could possibly imagine, plus $100 million.

The genres are widening. I don't think that there's as many limitations on the kinds of projects that actors can do as there once was.
