And finally, one final set of eccentrics: actor Klaus Kinski and director Werner Herzog, who clashed famously and formidably while making Herzog’s epic 1982 movie Fitzcarraldo. That movie was a based-on-fact film about an obsessed megalomaniac intent on bringing opera to the jungles of Brazil. This documentary, by Les Blank, is about the equally obsessed megalomania behind the making of that film. It features short but telling appearances by Mick Jagger and Jason Robards, the movie’s original stars, and provides a fascinating early portrait of Herzog, the visionary director currently represented by his new, amazing Into the Abyss documentary on volcanoes, produced for and available on Netflix.
