Basil Rathbone Zanuck at Lucey's Restaurant in Hollywood, proposed a film version of Sir Arthur Conan Doyle's "The Hound of the Baskervilles". When asked who could possibly play Holmes, Markey incredulously replied, ""Who?!" Basil Rathbone!" The film was so successful that Fox produced a sequel which appeared later in 1939. Interest in Holmes cooled at Fox, but Universal Pictures picked up the character, and twelve feature films were made between 1941 and 1944 for release until 1947, all of which co-starred Nigel Bruce as Dr. Watson. The first two films, "The Hound of the Baskervilles" and "The Adventures of Sherlock Holmes" (both
Basil Rathbone produced by Fox in 1939), were set in the late Victorian times of the original stories. The later installments, produced by Universal, beginning with "Sherlock Holmes and the Voice of Terror" (1942), were set in contemporary times. The first three had World War II-related plots. Concurrent with the films, Rathbone and Bruce reprised their film roles in a radio series, "The New Adventures of Sherlock Holmes", which began in October 1939. Rathbone appeared in the radio series as long as the film series was active, but after the films lapsed in 1946, Rathbone ceded his radio part to Tom Conway.
