'His films are like scenarios made from communities of rats, the camera itself a king rat,' David Thomson wrote of Fuller. The rat trap is the Korean war, in a studio set of fake rock and fake snow, literally a theatre of war. The constantly moving camera isolates the tensions within an American platoon fighting a rearguard action. As the leaders are picked off by the 'alien' reds, one sensitive corporal's struggle with the responsibilities of leadership drags the plot in a slow dance of death; only to be blasted apart by a typical cigar-chewing affirmation of good old Yankee guts. From John Brophy's novel Immortal Sergeant (previously filmed in 1943).
