Green Inferno (AKA Cannibal Holocaust II) is what you get if you suck all of the visceral power (and the cannibalism) out of Cannibal Holocaust. Like Deodato's infamous shocker, the film sees an intrepid female reporter and her team venture into the jungles of the Amazon to try and find a missing professor of anthropology. Unlike Deodato's film, it features no gruelling horror (unless you count the sight of a small carnivorous fish being extracted from a man's ass!), instead coming across like a National Geographic documentary crossed with a lame jungle adventure (with elements of humour). It certainly doesn't deserve to be associated with the king of all Italian cannibal movies.
Much of the film revolves around the protagonists stealing a plane and then trapping monkeys which they exchange for gas; this allows director Antonio Climati to include that genre staple -animal cruelty - but even these scenes lack the ability to shock or disgust (it's a wonder why he held back given his involvement with notorious mondo movies Africa Addio and Savage Man Savage Beast, both of which feature loads of animal violence). After successfully fuelling their stolen plane, the characters have a run in with angry natives that amounts to nothing, are attacked by bats, meet a topless jungle beauty, are captured by river pirates who are harvesting the organs of indigenous children, and eventually locate the missing professor, who is perfectly fine. No cannibalism involved whatsoever.
