Black Friday (1940) 

 

    Dr. Sovac transplants the brain of a gangster into his professor friend's body to save his life, but there is a side effect that causes a dangerous split personality.

    When his friend Professor Kingsley is at deaths door, brain surgeon Dr. Sovac saves his life by means of an illegal operation that transplants part of injured gangster Red Cannon's brain. Unfortunately, the operation has a disastrous Jeckll and Hyde side effect and under certain conditions the persona of Cannon emerges. Sovac soon learns of the duel personality and of half a million dollars the gangster has hidden away. He attempts to find the money through the manipulation of his friend, an attempt that brings Kingsley closer to madness as he alternates between a meek professor of English and a brutal gangster out for murderous revenge on those who tried to kill him.
