Wow. Well, you get what you put up with, clearly. Herzog is a madlad.

Fitzcarraldo is one of the worst production experiences I could point to. The whole movie was shot on location, and without special effects. It was exactly as hard and dangerous to haul the boat over the mountain for the cast and crew as it was for the characters in the story. So many people were injured and killed during the production that Werner Herzog has been accused of colonialism and slaving. A small war between native tribes people and the mercenaries that Herzog hired to protect the production nearly broke out. A cameraman even took an arrow to the neck at the height of tensions.
 
Klaus Kinski clashed with Werner Herzog constantly, as he did in the rest of the films they made together. Kinski terrified the cast and crew with his legendary, sometimes violent, meltdowns to the point that one of the extras, the chief of one of the local tribes, went to Herzog and offered to disappear his body in the jungle.
 
A border war between Peru and Ecuador occurred during filming. The production was only a few dozen kilometers from the front.
