The dark European sci-fi fright-fest Lifespan (1974) focuses on a mad scientist (Hiram Keller) doing what men of his profession do (especially in scary movies): practicing mad science. Specifically, here, the deranged doctor is attempting to ward off human death through a series of experiments on numerous subjects--some willing, most quite screamingly not. That the maniacal medico is in cahoots with a pharmaceutical expert played by legendary madman Klaus Kinski should reveal quite a bit about how this thriller plays out. Add into the mix tantalizing Tina Aumont and your Lifespan may not lengthen, but the front of your pants certainly will.
