I first caught this film midway through, when it was on IFC. Not only did it stop me in my tracks, but I looked up to see when it would next be on so I could set the VCR. Though Herzog attempts to portray himself as the cool and reasonable half of this dastardly duo, his own megalomania and ego shine through. This documentary catches on film the fine edge between brilliance and insanity, and the result is simply stunning. This is not a biography of Kinski but rather a kind of valentine to him that celebrates his (and Herzog's) mad genius.
