In World War II, a shot-down American pilot (Lee Marvin) and the marooned Japanese Captain Tsuruhiko Kuroda (Toshiro Mifune) are stranded in a small island in the Pacific. When they find the presence of each other, the American tries to steal the water provision of the Japanese that protects it, initiating their personal war. After a period fighting each other, they decide to join forces and build a bamboo raft to seek a larger island.

"Hell in the Pacific" is a good movie about how struggle to survive supersedes any other feelings even in times of war. The Japanese and the American soldiers find how pointless is their fight and resolve their situation joining forces and learning to accept and respect their culture differences despite the language barrier and warfare. Surprisingly they also become friends but the abrupt conclusion is too stupid and meaningless, apparently imposed by the studio. The alternate ending is also terrible but better then the original one. In 1985, Wolfgang Petersen used the same idea in a futuristic environment in "Enemy Mine". My vote is seven.

Title (Brazil): "Inferno no Pacífico" ("Hell in the Pacific")
