Jack the Ripper was a 1959 film produced and directed by Monty Berman and Robert S. Baker and is loosely based on Leonard Matters' theory that the Ripper was an avenging doctor. The black-and-white film starred Lee Patterson and Eddie Byrne and co-starred Betty McDowall, John Le Mesurier, and Ewen Solon.
In 1888, Jack the Ripper is on his killing spree. Scotland Yard Inspector O'Neill (Byrne) welcomes a visit from his old friend New York City detective Sam Lowry (Patterson) who agrees to assist with the investigation. Sam becomes attracted to modern woman Anne Ford (McDowall) but her guardian, Dr. Tranter (Le Mesurier) doesn't approve. The police slowly close in the killer as the public becomes more alarmed. The killer's identity is revealed and the killer meets a ghastly end.
