How is it this Creature Double Feature sci-fi gem, which stars Nancy Reagan no less, hasn't made it to our Monster List? Dr. Patrick Cory is a good man, he is dedicated to his work, loves his wife Janice and is an all around stand up guy. When Donovan, a millionaire with a nasty demeanor dies, Dr. Cory cannot resist the opportunity to confuscate his brain. He keeps the brain alive in a tank with some nasty liquid and electrodes so he can attempt to tap into it but the experiment goes haywire and Donovan's brain telepathically takes control of Dr. Cory forcing him to behave much out of character. It's up to his wife and his drunken lab assistant to destroy the brain before it destroys Cory.
I think I'll name him Ronald
