Green Inferno on AllMovie

Though one of the many titles of this exploitationer is Cannibal Holocaust II, it bears little if any relation to the infamous Cannibal Holocaust. In fact, Green Inferno would seem to have been conceived in the shadow of Apocalypse Now --or, perhaps, Heart of Darkness. An eccentric professor who lives deep in the Amazon jungles disappears, so an expedition team of one woman and three men head out to locate him. En route, they encounter a whole plethora of dangers, including cannibalistic fish, headhunters, massive venomous snakes and all sorts of other ills.
