Hell in the Pacific, starring Lee Marvin and Toshirô Mifune

(http://www.imdb.com/title/tt0063056/)

In the last scene when they find an old battle ground (after struggling against the sea) and they can get more "civilized" (shaved, cleaned up) and find things like Saki, a LIFE magazine and Chocolate Wafers. Its a real cruncher.

Not what you were asking for, but man the whole movie is a missed Gem!
