"One At A Time" is a story about a German squad sole survivor Erich (excellently played by Jan Merlin) who, shocked by the loss of his comrades, sets out for revenge after overhearing American plans.
Esther & Bob Mitchell wrote a good screenplay in that the story flows logically. Character development is adequate with the group exuding fear & apprehension. The opening sequence portrays excellent combat firepower, the essence of Combat.
Director McEveety uses backdrop and camera angle to get the intimidating flash of automatic weaponry. He gets some excellent close-ups of both the fearful Americans and Erich, who emphatically exudes hatred & revenge. His shoot of Private Peal hunting down Erich is outstanding.
The ending sequence is unspectacular; Saunders a bit lucky. I'd hoped for a little more creativity from Writers' Mitchell. All & all "One At A Time" will keep the viewing audience in suspense.
