There were the classic challenges any tourist faces, like getting lost, getting sick, losing things, getting in a fight... All these things happened numerous times. The only point of the trip that was defiantly challenging was a point that's not actually in our film.

Fitzcarraldo is that metonymic character that's unwilling to give up on his dreams. Meeting Walter was the point in which all of these dreams coalesced into a very real person with a very real story.

Fitzcarraldo is a mad dreamer. He's willing to sacrifice everything in order to make his vision of an opera house. That metaphor of pulling the boat over the mountain is so integral to anyone making any creative effort. It's that universal Sisyphean struggle.

It's organic. It's like a river. One stream comes in and it meets another stream and becomes the Amazon.

I worked on "Tree of Life." It was just magical. It was like a little family. A fleeting, beautiful alliance to forge something meaningful. It was amazing, like a transcendental experience to be on the set.

Herzog and Malick both have this very unique naturalist intentionality to their process. It's about creating the mood, creating the focus and having discipline, but not prescribing what the performance was supposed to be. Neither of them are really directing their actors into a performance.
