At one point, we were stuck at the border of Peru and Colombia and met this large Haitian population that was stranded there without passports and couldn't move. We had this revelation that, as tourists, we were so free to move, and here was this other population who couldn't cross borders.

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.

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.

Because of Walter, we did it the other way around. We also worked with an awesome sound designer named Will Patterson who just worked for four years on Terrence Malick's films. He did a lot of conceptual work to make the soundscapes in the jungle have this surreal quality, to blend these two films because a lot of the images are about this parallelism between the movies. The sound was very integral to fusing everything.

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.
