THE NEANDERTHAL MAN (1953) To prove a point about the evolution of the brain, a scientist invents a syrum that reverts people and animals back to the stone age.
This film would make a good double bill with
Monster On Campus(1958), both have similar themes. The only thing that lets this film down is the make up. It is and looks like a cheap rubber mask from a joke shop.Worth checking out if you are a fan of 'nutty scientists'.
