Hell in the Pacific

Hell in the Pacific is a 1968 World War II film starring Lee Marvin and Toshir Mifune, the only two actors in the entire film. It was directed by John Boorman.

The film contains little dialogue, and much like its predecessor the film None but the Brave is not dubbed or subtitled, thus authentically portraying the frustration of restricted communication between the Japanese and Englishspeaking. The film was entirely shot in the Rock Islands of Palau in the north Pacific Ocean, near the Philippines in the Philippine Sea.The film was originally released with a rather abrupt ending, one that left many dissatisfied with the outcome of the struggle these men endured. The subsequent DVD release has an alternative ending, which while leaving the eventual destiny of the two ambiguous, was much more in line with the overall direction of the movie. ........
