While I love Herzog's nonfiction, his narrative films of the '70s and '80s tend to stick with me longer after viewing. The turbulent Klaus Kinksi collaborations -- most notably Aguirre: The Wrath of God and Fitzcarraldo -- are watchable and rewatchable almost without exception, yielding new perspectives and revelations with each viewing. He made equally strong work with the tragic, troubled Bruno S., resulting in the tandem of The Enigma of Kaspar Hauser (1974) and their wild American sojourn Stroszek (1977).
But pound for pound, nothing beats Heart of Glass (1976), a sublime bit of insanity about a Bavarian village thrown into uncertainty after the local glassworks proprietor dies, taking the secret of his lucrative "Ruby Glass" with him to the grave. Interesting enough, but then Herzog went and hypnotized the entire cast. A sort of psychic languor ensues, beautifully reflecting the trancelike effects of crisis on individuals and community. It's not without its dark humor, either -- hypnosis does funny things to people -- but Herzog's narrative anchors the experiment against shipwrecking in the shallow waters of exploitation.
Nevetheless, the best thing in Heart of Glass is the one scene Herzog acknowledged was too dangerous for hypnosis: The glassblowing montage. Here the filmmaker's documentary gifts harmonize with his dramatic instincts in a way his work has emulated in the decades since with varying degrees of success. Mind-blowing commences right around the 2:00 mark.
