Donovan's Brain

“A dead man's brain in a hidden laboratory told him to KILL... KILL... KILL”

Dr. Patrick Cory (Lew Ayres) is a scientist who takes the brain of a dead man and keeps it alive in a tank of liquid, wired up with electrodes. Felix E. Feist shoots most of it in close rooms where the tank hums at the edge of every frame. Cory's wife Janice (Nancy Reagan) watches her husband start to speak and act like someone else.
