Not to be confused with the earlier Tobe Hooper killer crocodile flick, this is director Umberto Lenzi's second cannibal flick(his MAN FROM DEEP RIVER back in 1971 pretty much invented this subgenre). This is the one that combines a very Jim Jones-inspired cult in the jungle story with your more typical cannibal antics. Instead of The Amazon this time we're in New Guinea and Lenzi doesn't skimp on the gore. Of course a good portion of the most gory bits are all from other movies including DEEP RIVER, SLAVE OF THE CANNIBAL GOD and JUNGLE HOLOCAUST but hey it's the thought that counts! Porn star R. Bolla(Robert Kerman) stars and he would return in Lenzi's final cannibal epic CANNIBAL FEROX the following year.
It's hard to rank these classic cannibal movies in order of entertainment value since they're all pretty similar. This one is somewhere in the middle for me with FEROX and CANNIBAL HOLOCAUST being on the top though.
