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.

I identify with someone wanting something to work out, but not being able to get through the rocks to the river.

I think I've always been half out of my shell and half in. Sometimes I can be extremely wild and sometimes I can be extremely shy. It just depends on the day.

I was so grateful to have made 'Into the Wild' before I made 'Speed Racer' because on 'Speed Racer' I was indoors every single day, every single scene, on a green screen. Some of the time, just to pass the time, I would think back to climbing mountains in Alaska. That really helped me.

Maybe you will be afraid and maybe you will fail, but the courage to take risks in any part of your life is, I feel, a very worthwhile way to live.

I'm not a ball in a pinball machine. I know what I want.

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.
