Darktower.net: Prior to Orson Welles achieving fame for Citizen Kane (1941), The Lady from Shanghai (1948), and Touch of Evil (1958), he and his troop of gifted actors made a living performing live broadcasts such as War of the Worlds for weekly radio shows. One of these weekly programs, a show called Suspense, featured half-hour dramas full of (you guessed it) suspense! In 1940, the show featured Orson Welles performing a play titled The Dark Tower by George S. Kauffman. Obviously, this play does not relate to King's Dark Tower, however it is interesting to note that at the start of the broadcast, the announcer says "This is the man in black here to introduce this weekly half-hour of Suspense!..." Hmmm...some coincidence isn't it.
