Mann's bold fusion of World War II melodrama and gothic horror concerns an implacable Nazi officer (Prochnow) whose occupation of a remote Transylvanian castle stirs up a long-dormant Lovecraftian demon. If the Tangerine Dream sound is "like silt seeping on the ocean floor" (as Lester Bangs put it in a 1977 concert review), then The Keep is the essential Tangerine Dream showcase, a film that seemed to coalesce just so Edgar Froese and company could creep through stone corridors for two hours. A murky but enormously evocative film maudit with multiple alternate endings (available on YouTube), The Keep was semi-disowned by its director and remains unreleased on DVD or Blu-ray; in other words, it's a certifiable cult item with a growing reputation, and its inky blacks are a must-see on 35mm.
