Masterpiece.

Rating: 10/10 (18 December 2016)

In early 1943, World War II British prisoners arrive by train at a Japanese prison camp in Burma. The commandant, Colonel Saito (Sessue Hayakawa), informs them that all prisoners, regardless of rank, are to work on the construction of a railway bridge over the River Kwai that will connect Bangkok and Rangoon. The senior British officer, Lieutenant Colonel Nicholson (Alec Guinness), reminds Saito that the Geneva Conventions exempt officers from manual labor.
At the following morning's assembly, Nicholson orders his officers to remain behind when the enlisted men are sent off to work. Saito slaps him across the face with his copy of the conventions and threatens to have them shot, but Nicholson refuses to back down. When Major Clipton (James Donald), the British medical officer, intervenes, telling Saito there are too many witnesses for him to get away with murdering the officers, Saito leaves the officers standing all day in the intense tropical heat. That evening, the officers are placed in a punishment hut, while Nicholson is locked in an iron box.
