RKO Pictures is an American film production and distribution company. It was one of the Big Five studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum (KAO) theater chains and Joseph P. Kennedy's Film Booking Offices of America (FBO) studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RKO has long been celebrated for its cycle of musicals starring Fred Astaire and Ginger Rogers in the mid- to late 1930s. Actors Katharine Hepburn and, later, Robert Mitchum had their first major successes at the studio. Cary Grant was a mainstay for years. The work of producer Val Lewton's low-budget horror unit and RKO's many ventures into the field now known as film noir have been acclaimed by film critics and historia
