Boris Karloff's third feature in Britain, filmed April 25-June 6 1936, quickly following "Cerveaux de rechange (1936)." He returned to Hollywood to shoot "Charlie Chan à l'opéra (1936)."
This film is one of over 200 titles in the list of independent feature films made available for television presentation by Advance Television Pictures announced in Motion Picture Herald 4 April 1942. At this time, television broadcasting was in its infancy, almost totally curtailed by the advent of World War II, and would not continue to develop until 1945-1946. Because of poor documentation (feature films were often not identified by title in conventional sources) no record has yet been found of its initial television broadcast. It's earliest documented post-WWII telecasts occurred in New York City Friday 19 November 1948 on WCBS (Channel 2), in Los Angeles Wednesday 16 February 1949 on KFI (Channel 9), in Chicago Tuesday 17 May 1949 on WNBQ (Channel 5), and in Salt Lake City Tuesday 18 October 1949 on KDYL (Channel 4).
