"Screen Directors Playhouse (sometimes written as Screen Directors' Playhouse) is an American radio and television anthology series which brought leading Hollywood actors to the NBC microphones beginning in 1949. The radio program broadcast adaptations of films, with original directors of the films sometimes involved in the productions, although their participation was usually limited to introducing the radio adaptations and taking a brief "curtain call" with the cast and host at the end of the program. During the 1955–56 season, the series was seen on television, focusing on original teleplays and several adaptations of famous short stories (such as Robert Louis Stevenson's "Markheim").
The radio version ran for 122 episodes and aired on NBC from January 9, 1949, to September 28, 1951, under several different titles: NBC Theater, Screen Directors Guild Assignment, Screen Directors Assignment and, as of July 1, 1949, Screen Directors Playhouse.
Actors on the radio series included Fred Astaire, Lucille Ball, Tallulah Bankhead, Charles Boyer, Claudette Colbert, Ronald Colman, Gary Cooper, Joan Crawford, Bette Davis, Marlene Dietrich, Kirk Douglas, Irene Dunne, Douglas Fairbanks Jr., Henry Fonda, Cary Grant, William Holden, Burt Lancaster, James Mason, Ray Milland, Gregory Peck, William Powell, Edward G. Robinson, Norma Shearer, Barbara Stanwyck, James Stewart, John Wayne, and Loretta Young."
