Well, the kind of central question: "Do you want to live - and I don't mean stay alive - do you want to feel your life while you're living it?" You know, there's somewhere to go that was here before we were and is going to be here after us, so get out there in it. It doesn't take somebody who's got some self-important sense of their own attachment to nature to recognise that you're just stupid if you don't go out there.

I don't think you can get away with putting your talents in a toilet bowl and not having them flushed away. Forever. There is a level of murder of one's soul and of the culture that they're supposed to be feeding vitamins to.

Yeah, I had a tremendous time shooting in Nebraska. I like that state a lot, all over it.

I can't imagine being quite as lucky at any other time - I certainly never have been before. That goes right down from my producing partners to people like Eddie Vedder. But the two things that make me feel that this was meant to be now and not before was that the story itself has more resonance today - I find it a more important story today than it was then - and Emile.

It's a foreground of my feeling. That place moves me. And I don't mean my country; it's part of our shared natural world that happens to be particular to a sense of wherever my storytelling inclinations come from and my own history of kind of being a road rat and travelling.

I can tell you that my contribution based on my interpretation of the book is unchanged. The other things, in terms of doing the research and following the trail of it, were probably pretty similar to what I would have done then. I think that what makes me celebrate that it took the 10 years is the various other people and contributors that I ended up having on board.

I get a little scared of words like maturity.
