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.

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.

The biggest lesson we took was when Werner [Herzog] said in a meeting with us that the mother of all challenges is to get your film seen in theater. To finally share this film has been so gratifying. The way audiences have responded, too.

First, the three of us holed up in winter in a cabin and took the 500 hours down to twelve hours. Then we found an editor, Lambis Haralambidis. He took that twelve hours and brought it to five. Then we get together and started taking the ax and chopping off different parts of our film.

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.

Malick is so far on the other side of the spectrum in terms of his character. Malick is a complete recluse, and not at all driven by ego or championing who he is as an individual. It's all about the art. Whereas Herzog is constantly placing himself into the engine. Malick is such a gentle poet.
