This movie was originally released in 1972 under the title, "SACRIFICE." Ivan Rassimov plays a Swedish John Bradly (Sven) who gores to Thailand as a photographer along with his blond gf. (Like bringing sand to the beach.) They attend a kick-box tournament with the Thai crowd going wide as if it was the WWF. She gets bored and leaves. He gets drunk and in a bar fight, kills a man, then flees to the jungles between Burma and Thailand were he is captured by a sadistic tribe, who eventually make him one of them. The acting was fairly decent. The plot was one we have seen many times. There is a lot of animal violence in addition to people violence. While this film is recognized as the first cannibal horror film, it lacks much of the "horror" cannibalism and gore of later films.
