Rent Mountain of the Cannibal God (1978)

Susan Stevenson (Ursula Andress) and her brother Arthur (Antonio Marsina) go to Manilla for the purpose of organising a search party for Susan's husband, a famous anthropologist, who has disappeared during a mysterious expedition, on one of the larger islands of the archipelago. No one knows for sure the purpose of his expedition, not even Dr. Foster (Stacy Keach), Stevenson's close friend and collaborator. By examining the last parts of the film shot during Stevenson's expedition, they are able to ascertain that he penetrated the jungle right up to Mount Rarami, the mountain of spirits, considered taboo by the natives. Set in the jungles the story unfolds of the mountain and it's curses.
