Screen Directors' Playhouse was a popular American radio and television anthology series that featured leading Hollywood actors performing adaptations of well-known films. The radio program invited the original directors of the films to sometimes take part in the production, often introducing the radio adaptations and making brief curtain-call appearances alongside the cast and host at the end of the show. The television version of the show, which aired during the 1955-56 season, focused mostly on original teleplays and several adaptations of famous short stories, such as Robert Louis Stevenson's "Markheim."
The radio version of Screen Directors' Playhouse aired for 122 episodes on NBC from January 9, 1949, to September 28, 1951, under various titles including NBC Theatre, Screen Actors Guild Assignment, Screen Directors Assignment, and eventually Screen Directors' Playhouse as of July 1, 1949. The show featured prominent actors of the time such as Fred Astaire, Lucille Ball, Gary Cooper, Joan Crawford, Bette Davis, Cary Grant, and John Wayne. The television version of the program, produced at Hal Roach Studios, lasted for one season consisting of 35 half-hour episodes, airing on NBC from October 5, 1955, to June 1956, and subsequently on ABC until September 26, 1956.
