The Bridge on the River Kwai

Director David Lean's sweeping epic -- best known for a whistling work theme that became legendary -- is set in a World War II-era Japanese prison camp where British POWs are forced to construct a railway bridge as a morale-building exercise. Yet the real battle of wills is between a "play by the rules" British colonel (Alec Guinness) who's dedicated to the project and his American rival (William Holden), who vows to destroy it.
