Ruggero Deodato directed this gory cannibal movie, one of many to pour out of Italy in the wake of Il Paese del Sesso Selvaggio (1972), which also starred Me Me Lay and Ivan Rassimov. Rassimov's plane crashes in the Amazon jungle, and he is soon captured by a Stone-Age tribe, which tries to kill him -- until a native woman (Lay) frees him for sex and pays with her life. There is real mondo-style footage of animals devouring each other to go along with staged horrors such as Lay being gutted and having her body cavity filled with hot coals. Deodato returned with the more extreme Cannibal Holocaust a few years later.
