This movie is hard to categorize. Klaus Kinski has a minor part, so it really can't be considered an important Kinski movie. It is not a horror film, with only one unsettling grave desecration scene. What it is, is an intelligently made sci-fi, that deals with the unique subject of trying to overcome death, by extending lifespans. Beautifully filmed in Amsterdam, the film has sharp editing, and narration that keeps things on track, Hiram Keller is the rather detached American scientist who is trying to unravel a dead colleague's immortality experiments. Klaus Kinski is the Swiss pharmaceutical company owner seeking death control for his own use. Tina Aumont is a love interest for both Keller and Kinski, with her totally gratuitous bondage scene unnecessary except perhaps for some titillating promotion. The ending leaves things hanging uncomfortably, but if you go in with realistic expectations, "Lifespan" will reward. - MERK
