One of the lesser known cannibal films from the late 70's, which was actually an Indonesian production for a change, rather than an Italian one, who were dominating the cannibal sub-genre during this period. This one revolves around a group of students, who go into the Pangayan jungle to observe the primitive tribal customs of one of the native villages, only for things to go awry.
Deciding that the local tribesmen are a bit too civilised to be worthy of study, they bribe their guides to take them deeper into the jungle in search of some real primitives, with predictably grim results. As their raft overturns, the group becomes separated, and they find themselves being picked off by the local wildlife and a tribe of cannibals that happen to be living nearby.
Captured and dragged back to their cave, the surviving members of the group are subjected to various indignities, as the tribe prepare to turn them into their next meal (though I'm not sure native women would be wearing lipstick and eye shadow, as evidenced here). Cannibal film aficionados may get more than just a feeling of Deja-Vu whilst watching this, not least because it appears to borrow several scenes from "Last Cannibal World", including footage that was lifted directly from it.
Certainly one of the more unusual cannibal movies, although perhaps the most bizarre thing about is the soundtrack, which not only opens with the song "We are the Robots" by 70's techno artists "Kraftwerk", it also utilises tracks from the likes of Jean Michelle Jarre, Klaus Wunderlich and even lifts some of John Williams "Star Wars" music.
Not quite as gory or violent as the other films of this ilk, with the exception of a few yucky scenes of animal killing (an alligator being gutted and an orang-utan having its head split open), but it's certainly odd enough to warrant a viewing by cannibal film enthusiasts.
