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.

What we definitely agree with Walter on is that filmmaking is teamwork. It's one of the only arts that is truly based in the work of a team. Anyway, Werner he told us a lot of practical things. How to hang a hammock. He'd circle a map and give us a notebook with directions to get to certain places that were out of the way. He told us to drink the river water and not use purifications tactics that only "New Age assholes" used. He said that if we saw piranhas, we should jump in and swim with them. We did all of this. We took his word as gospel.

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

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.

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.

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.

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.
