The Elusive Corporal(1962)

Original title: Le Caporal épinglé

An upper-class corporal is captured by the Germans during their 1940 invasion of France. Assisted and accompanied by characters as diverse as a morose dairy farmer, a waiter, a myopic intellectual, a working-class Parisian, and a German dental assistant, the corporal tries to escape from prison camps, sometimes making it a few yards, sometimes reaching the border.
