This Korean War drama is essentially a vehicle for RKO's top male star Robert Mitchum. He plays war-weary "Colonel Steve," obliged to contend with the North Korean forces while keeping troublesome UN official Linda Day (Ann Blyth) at arm's length. Some authentic Korean combat footage is well-integrated into the story. For all its talk about jet planes, Reds and atomic energy, the film is at base a redressed WW II drama. Good supporting performances are provided Charles McGraw as a tough sergeant and William Talman as a jet pilot. Reportedly budgeted at over two million dollars, One Minute to Zero had trouble making back its cost, despite the box-office pull of Robert Mitchum.
