The Brain That Wouldn't Die (1962)

A surgeon (Jason Evers) with radical ideas and a Frankenstein-esque zeal for experimentation gets the opportunity to put his ideas into practice when he comes into possession of a severed female head.
It's hilariously bad at times, but that's only half of the story. Beneath the wooden acting there's a very sick-minded, twisted male lead to keep the story moving forward; you only need to analyse his motivations and actions to discover it. The dark humour that clings to him is very dark indeed.
The scenes with the head on a desk are fantastic. Virginia Leith bubbles with hatred just as the tubes that keep her alive are bubbling with mystery fluid.
If Hammer Studios had made it, upping the production values to their highest standards, it could've equalled even their own best efforts.
