The Grand Illusion (1937) 大幻影

La Grande Illusion (also known as Grand Illusion) is a 1937 French war film directed by Jean Renoir, who co-wrote the screenplay with Charles Spaak. The story concerns class relationships among a small group of French officers who are prisoners of war during World War I and are plotting an escape. The title of the film comes from the book The Great Illusionby British economist Norman Angell, which argued that war is futile because of the common economic interests of all European nations. The perspective of the film is generously humanistic to its characters of various nationalities.

During the First World War, two French soldiers are captured and imprisoned in a German P.O.W. camp. Several escape attempts follow until they are sent to a seemingly impenetrable fortress which seems impossible to escape from.
