It Happened One Night: Classic Movies on the Radio

This radio dramatization of the classic movie, which won the Academy Award for Best Picture, features the original stars: Clark Gable, who was named Best Actor, and Best Actress winner Claudette Colbert. It aired on March 20, 1939.
The Lux Radio Theatre was one of radio's most popular series, attracting Hollywood's top stars and boasting a lavish budget. It began in 1934 by featuring dramas from Broadway, but there was not enough material to support the show. In an attempt to reverse the slipping ratings, the show was moved to Hollywood in 1936, where there was plenty of material and talent. In fact, filmmaker Cecil B. DeMille often served as the host.
