Adaptations of Sherlock Holmes Conway played Sherlock Holmes opposite Nigel Bruce for one season. After a change of networks, there were two more pairings: John Stanley as Holmes and Alfred Shirley as Watson in 1947–1948 and Stanley and "George Spelvin" in 1948–1949. Both Stanley and Conway emulated Rathbone when performing Holmes to aid in continuity for the audience. John Gielgud played Holmes for BBC radio in the 1950s, with Ralph Richardson as Watson. Gielgud's brother, Val Gielgud, appeared in "The Bruce-Partington Plans", perhaps inevitably, as Mycroft Holmes. As this series was co-produced by the American Broadcasting Company, known American actors also appeared, such as
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.
