Lodger story but was based on a 1948 radio play by Margery Allingham. It was one of the first horror pictures made by Hammer Film Productions. Valentine Dyall plays the lodger, "Dr. Fell", who has escaped from a lunatic asylum where he has been incarcerated for 16 years since committing the Whitechapel murders. Hammer released two Ripper-inspired films in 1971. In Hands of the Ripper, the Ripper's daughter (played by Angharad Rees) grows up to become a murderess after she sees her father kill her mother. In Dr. Jekyll and Sister Hyde, Dr. Henry Jekyll transforms into the evil predatory woman Sister Hyde and is also responsible for the Ripper murders. In Terror in the Wax Museum (1973), a murderer disguises himself as a waxwork of the Ripper. The Veil episode "Jack the Ripper" (1958) is a made-for-television film introduced by Boris Karloff, in which a clairvoyant identifies the Ripper as a respectable surgeon whose death has been faked to cover his incarceration in a lunatic asylum. The story's basis was an 1895 newspaper report that Robert James Lees had used psychic powers to track the Ripper to the home of a London physician. Jack the Ripper (1959), produced by Monty Berman and Robert S. Baker and written by Jimmy Sangster, is loosely based on Leonard Matters' theory that the Ripper was an avenging doctor. It borrowed icons from previously successful horror films, such as Dracula (1958) and The Curse of Frankenstein (1957), by giving the Ripper a costume of a top hat and cape. The plot is a standard "whodunit" with the usual 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. However, Matters used the ploy of the son dying from venereal disease, while the film has him committing suicide on learning his lover is a prostitute. In a reversal of this formula, the German film Das Ungeheuer von London City (1964), released as The Monster of London City in 1967, casts the son as the villain with the father as the victim of syphilis. Pandora's Box (Die Büchse der Pandora) is a 1929 German silent film directed by Georg Wilhelm Pabst based on Frank Wedekind's play about a woman,
