Orson Welles as Sherlock Holmes? While it never happened on the big screen it did happen in the golden age of radio. On September 25, 1938, Welles and his Mercury Theatre Players hit the airwaves with their adaptation of the popular William Gillette play. Welles wrote the radio play and his vision of The Immortal Sherlock Holmes came to life on his radio program, Mercury Theatre on the Air. This program aired a little more than a month before the infamous War of the Worlds broadcast.
So, put down the violin, settle down in front of the warm fire and go back to the late 1800s as the master detective Sherlock Holmes prepares for one of his greatest mysteries.
