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.

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.

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.

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.

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.

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

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.
