Slave of the Cannibal God

After creating some of the best gialli of the '70s, director Sergio Martino entered the cannibal cycle with this "blood and guts gorefest" (Trailers From Hell): When a British scientist disappears in the jungles of New Guinea, his wife (Ursula Andress) hires an American anthropologist (Stacy Keach) to lead her deep into the green inferno.
