The Lux Radio Theatre was one of the longest running—and most extravagant—shows from radio's golden age. The show featured the greatest stars in Hollywood appearing in hour-long radio adaptations of their biggest motion pictures. Cecil B. DeMille was the host for the lavish production of what was to become a veritable checklist of many of Hollywood's best films from the mid-1930s through the mid-1950s. The stars of the movie usually appeared in their audio counterparts, although sometimes contracts or schedules meant that another actor took the part. The productions were live, with a full orchestra, and many Hollywood legends were not used to performing in public without the benefit of retakes. The greatest film legends appeared on The Lux Radio Theatre including: Humphrey Bogart, Barbara Stanwyck, Cary Grant, Clark Gable, Frank Sinatra, John Wayne, James Stewart, and Loretta Young, to name a few. Sponsored by Lever Brothers, the makers of Lux Soap, The Lux Radio Theatre came to radio in 1934 and lasted until 1955 for a total of 926 hour-long broadcasts. It transitioned to television in thirty-minute weekly installments in 1950, with James Mason as host.
