I saw this movie at a USMC base Recreation Hall in Japan in 1989. I saw it again in the states around 1991 on TV. The premise was a journey through the desert. At one point in the desert the journey man/group? come upon a man naked in a barrel filled with liquid. He/they ask him what he is doing in the pickle barrel and he says he is pickling his dick because it is of no use to him/causes him pain from memory of unrequited love? It was in color and I can’t remember if it had subtitles or not.
