Jack the Ripper is a 1959 film produced and directed by Monty Berman and Robert S. Baker. It is loosely based on Leonard Matters' theory that Jack the Ripper was an avenging doctor. The black-and-white film stars Lee Patterson and Eddie Byrne and co-stars Betty McDowall, John Le Mesurier, and Ewen Solon. It was released in England in 1959, and shown in the U.S. in 1960.The plot is a "whodunit" with false leads and a denouement in which the least likely character, in this case "Sir David Rogers" played by Ewen Solon, is revealed as the culprit. As in Matters' book, The Mystery of Jack the Ripper, Solon's character murders prostitutes to avenge the death of his son. While Matters had the son dying from venereal disease, the film has him committing suicide on learning his lover is a prostitute.
