I've never seen Herzog's Aguirre, the Wrath of God but after reading this Roger Ebert post about watching 17 minutes of the film with the director I feel somehow that this method might be the ideal way to view it.
Herzog had only one take. He would never be able to persuade his actors to climb again for a second one. As we watched them descend, he froze the DVD frame to discuss several of the actors. A fat man who ate all the mangos. A close friend, semi-literate, who had bicycled 35,000 km around North America and later became a great photographer. Above all, his star Klaus Kinski, about whom some years later he made a film: "My Best Fiend."
Kinski, in constant rage. Describing himself as a "natural man" who could live in the forest like an animal. Then complaining that his tent leaked. Then complaining that the thatch shelter built over the tent leaked. Then moving at great inconvenience to the production into a shabby hotel where he beat his wife nightly, the crew discreetly removing the blood stains.
"A coward," Herzog says.
"Is it true," a voice from the dark asks, "that the Indians asked your permission to murder him?"
"No. That was on 'Fitzcarraldo'."
