United Artists productions/releases included The Mark of Zorro (1920), Stagecoach (1939) and the films of independent producers in the 1930s and 1940s such as Walt Disney, Alexander Korda and David Selznick. Later releases included most of the James Bond and all of the Rocky films, as well as One Flew Over the Cuckoo's Nest. It was owned for a time in the 1970s by the Transamerica insurance company, during which time the film The Hospital was released. After heavy losses incurred as a result of investing in the flop, Heaven's Gate, United Artists was acquired by Metro-Goldwyn-Mayer in 1981 and ceased to exist as a separate company.
