Technically, Reagan was a unit public relations officer, however Warner Brothers Studios and the American Army Air Corps had tapped him the previous year to star in a motion picture called Air Force. To allow filming to go forward, Reagan was transferred from his cavalry unit to the Air Corps' motion-picture unit in early January 1943.
Housed in the old Hal Roach studios, the First Motion Picture Unit (FMPU)--its acronym was pronounced fum-poo--produced military training, morale and propaganda films to aid the war effort. FMPU released Frank Capra's Why We Fight series and a documentary of the bomber Memphis Belle, the crew of which completed a standard-setting 35 bombing missions in Europe. The films were screened on domestic training grounds and in troop camps overseas as well as in U.S. movie theaters.
Air Force, which was later renamed Beyond the Line of Duty, conveyed the true story of the heroic feats of aviator Shorty Wheliss and his crew and featured narration by Lt. Ronald Reagan. The documentary, intended to promote investment in war bonds, won an Academy Award in 1943 for best short subject. Reagan went on to narrate or star in three more shorts for FMPU including For God and Country, Cadet Classification, and the The Rear Gunner. Reagan also appeared as Johnny Jones in the 1943 full-length musical film This is the Army.
