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 don't have an interest in any car that isn't good for the environment, other than maybe an aesthetic quality in a picture book.

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

A lot of the stuff in 'Speed Racer' has never been done before, from it having a multi-tone, to it having a retro-cool family movie, to having the photo-realism with the CG-backgrounds and infinite focus the way they worked with these digital cameras, to even the color experimentation.

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

Brokeback Mountain' just blew me away. I'll always remember talking to Heath Ledger just after he finished that movie and he was going on about working with Ang and how incredible he was.

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.
