The turning point for me was when the Supreme Court installed Bush in 2000, even though he got half a million votes less nationally than Gore. It was nothing more than a bloodless coup and that's when I really started paying attention.
I was making a film called The White Tower at the foot of Mont Blanc - the one thing I learned from that experience was that it's more difficult to go down a mountain than to go up. A lot of people don't realize that.
