Motion pictures played an unprecedented role during World War II, with government agencies in America and around the world producing thousands of hours of films for training, orientation and public information. Prints of many of these films were deposited with the Academy for its War Film Library, which was established in 1942 as a service to the Hollywood film industry. The surviving prints form the nucleus of the Academy Film Archive's War Film Collection, a unique collection of documentaries, propaganda films, newsreels, and motivational shorts that demonstrate the powerful impact of motion pictures during wartime. These fascinating visual records are being saved for future generations through the preservation efforts of the Academy Film Archive. Highlights from the War Film Collection are presented here, along with selected items from the Academy War Film Library files, archived at the Margaret Herrick Library.
