Overview
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.
Plot
Just prior to the North Korean invasion of South Korea, World War II U.S. Army veterans Colonel Steve Janowski (Robert Mitchum) and Sergeant Baker (Charles McGraw) are teaching South Korean soldiers how to use a bazooka to stop an enemy tank. Linda Day (Ann Blyth) is a United Nations worker assisting refugees. Janowski warns Day and her colleagues to leave the area because hostilities are imminent. Day, however, insists that the North Koreans would not risk the wrath of world opinion. In response, Janowski asks her if world opinion stopped Hitler.
Soon after, Janowski and U.S. Air Force Colonel Joe Parker (William Talman) wake up and find themselves under attack. They compare the attack to Pearl Harbor ("Isn't this where we came in?" "It's even Sunday morning!"). Janowski takes command of a U.S. Army unit which is helping to evacuate Americans and refugees. While doing his job, he keeps crossing paths, and falling in love, with Day. It turns out that she is reluctant to get involved with a soldier because she is the widow of a Medal of Honor recipient.
As part of a desperate situation, Janowski is confronted by a column of refugees which has been infiltrated by armed North Korean guerrillas. He has no choice but to call in an artillery strike. Even though Janowski is remorseful for the civilian casualties, Day initially condemns him for killing innocent people. After she finds out the reason for Janowski's action (and that he was right), she apologizes.
