The Brain That Wouldn't Die - Extended Cut

Dr. Bill Cortner (Jason Evers) is an unethical scientist with a dim-wit girlfriend named Jan Compton (Virginia Leith). After a car accident decapitates Jan, Dr. Unethical snatches her severed head and hauls ass to his laboratory, where he revives it, and plots to give her/it a new body. Murder, horny mutants, bullshit scientific theory and pissed off zombie girlfriends ensue.
