Jungle Holocaust (1977) review

A team of prospectors travel to Mindanao (in the Philippines) and one of them, Robert Harper (Massimo Foschi), gets captured by the area's cannibals, tied up, stripped and tortured for days, but he's eventually helped by one of the women there (Me Me Lai) to escape (to reward her heroism, he rapes her).  As a warm-up for the notorious Cannibal Holocaust a few years later, Deodato relies on scenes of (very real) animal torture for "shock value" - which is indefensible - but I would be lying if I didn't find the middle section of the movie (you know, the part without the need for acting or dialogue) to be genuinely intense: Deodato actively works to disorient the viewer, and the nakedness of Foschi surrounded by all those strange and violent individuals heightens the feeling of claustrophobia.  I'll leave it to others to debate whether these types of movies work as an act of criticism against capitalism or a statement about man's capacity for pure evil and just say that any filmmaker that plays upbeat chamber music over one of the characters being dissected and consumed is either completely clueless or capable of the darkest humor.
