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.

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.

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.

So to watch that production was just the most insane vision of a filmmaker being unrelenting in his will to create. Learning more about that was what we wanted to do. To find out how in God's name anyone could do that.

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.

The lessons learned on a pure practical production standpoint were immense. It instilled a faith that you can accomplish what you want if you just believe and stick together and continue to work at it. In that sense, it gives me the confidence to go into the next project with the belief that we can do it. This was an experiment in whether you can find a film without a singular conceit.
