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.
