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.

Especially these days where everything is so polite and so proper, I think that rites of passage are good.

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.

I know what wanting and craving adventure feels like, I can really relate to that.

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 think that I have sold out sometimes.
