Abbott and Costello Meet Dr. Jekyll and Mr. Hyde is a 1953 comedy horror film directed by Charles Lamont and starring the comedy team of Abbott and Costello, and co-starring Boris Karloff.
Loosely based on the novel The Strange Case of Dr. Jekyll and Mr. Hyde by Robert Louis Stevenson, the film follows the story of two American detectives visiting Edwardian London who become involved with the hunt for Dr. Jekyll, who is responsible for a series of murders.
Slim (Bud Abbott) and Tubby (Lou Costello) are American cops in London studying police tactics. A newspaper reporter, Bruce Adams (Craig Stevens), gets into an altercation at Hyde Park that was instigated by Vicky Edwards (Helen Westcott), a suffragette. Bruce and Vicky wind up in jail, while Slim and Tubby are kicked off the police force. Dr. Henry Jekyll, Vicky's guardian, bails them out.
Jekyll has been conducting home experiments in which he injects a potion and transforms into Mr. Hyde, a monster who murders a fellow doctor...
