Samuel Fuller's valedictory war picture, The Big Red One follows the First Infantry Division from Africa to Europe during the years 1942 through 1945. Lee Marvin portrays the division sergeant; he's tough and experienced, to be sure, but he takes on his job with cool professionalism rather than Hollywood bravado. Based on Fuller's own experiences, the film is a loosely constructed series of anecdotes. Among them are an insane asylum under bombardment while the inmates applaud and a climactic vignette in which a very young concentration camp internee dies while a friendly soldier plays piggy-back with the boy.
