Ivan Rassimov plays American photographer John Bradley, on vacation in Thailand. He and his guide end up deep in the jungle, where he is abducted by a primitive tribe. They put him into a variety of tortures and trials, until finally accepting him as one of their own. He finds adjusting to this new life to be surprisingly agreeable, especially when he becomes smitten with Maraya (Me Me Lai), the lovely daughter of the tribes' leader.
Considered to the vanguard film in that jungle / cannibal genre popularized by the Italians, this is definitely a trail blazer, but people who've already seen more famous entries in the genre may be caught off guard with this one. It's more of a straight drama (heavily influenced by Elliot Silversteins' Western "A Man Called Horse") with touches of horror than a body munching / body count / exploitation feature. In reality, despite the presence of a hostile cannibal tribe in the film, only one person ever gets turned into a feast.
"Sacrifice!", a.k.a. "The Man from the Deep River", isn't without its gory pleasures, however. It benefits from excellent location shooting and utterly convincing local color. It's wonderfully shot, and scored, and is overall quite appealing and engaging. It's not to all tastes, though, because it includes some brief moments of animal cruelty that will turn off some members of the audience. This, of course, has only become one of the elements that recurs throughout many an Italian jungle adventure.
Rassimov is good as the hero. The intoxicatingly gorgeous Me Me Lai, who went on to appear in "Jungle Holocaust" and "Eaten Alive!" as well, is very easy to watch. (Viewers should be quite content with the amount of female nudity that is present.) The other performances are quite effective.
This is as good a story of both the beauty and savagery of nature as one could see.
Eight out of 10.
