Directed by: Anthony Mann
Starring: Robert Ryan, Aldo Ray, Robert Keith, Phillip Pine
Factual error: The Sergeant reminds the Lieutenant it is 0500 hours, but the scene shows a very bright mid-day, not early morning.
Factual error: The G.I.s are an army unit, but are wearing United States Marine Corps uniforms.
Factual error: Montana introduces himself as Sergeant First Class Montana, but his helmet and sleeve insignia shows the rank of Staff Sergeant.
Revealing mistake: A blank firing adaptor (BFA) is visible on the muzzle as the men set up the .30 caliber machinegun.
Lt. Benson: Battalion doesn't exist. Regiment doesn't exist. Command HQ doesn't exist. The U.S.A. doesn't exist... We're the only ones left to fight this war.
Trivia: A young Vic Morrow plays a green soldier in this film. A few years later he will be leading his own squad as a veteran sergeant in the TV series "Combat."
