One Minute to Zero is a 1952 American romantic war film starring Robert Mitchum and Ann Blyth, set during the opening phases of the Korean War, and produced by Howard Hughes as his last film as producer. Victor Young's score for the film includes the first appearance of "When I Fall in Love", as the instrumental titled "Theme from One Minute to Zero". The film showcases the contributions of the U.S. Army and U.S. Air Force, the South Korean Army, the United Nations, the British Army and the Royal Australian Air Force during the early days of the Korean War. The effects of air power in the Korean War were also vividly depicted through the use of combat footage.
