The Man Without a Body

Medical science goes berserk when Brussard (George Coulouris), a wealthy man who is suffering from a brain tumor, seeks the help of Dr. Merritt (Robert Hutton), a mad scientist who experiments with surgically mixing-and-matching monkey heads with different monkey bodies. Upping the ante, Brussard steals the head of Nostradamus from the ancient seer's crypt, with every intention of transplanting the oracle's noggin onto his own body.
