Long but suspenseful, 36 HOURS from 1964 presents James Garner as a military man who knows all the info about the planned Allied Invasion of Europe. He's kidnapped by the Nazis who attempt to get him to reveal the info via an elaborate ruse that makes him think the war is long over and it's 6 years later.
Garner is restrained but good. The easy charm he usually exudes comes here instead from Rod Taylor as the Nazi who learns so much about his prey that he learns to respect him more than his masters.
Eva Marie Saint heads up the rest of the excellent cast that included even an appearance by TV's Sgt. Schultz, John Banner, doing something very un-Schultzlike.
