A photographer accidentally kills a man in self-defense and while retreating into the jungles of an Asian country, is captured by a native tribe who hold him captive, force him into slave labor, and eventually accept him when he marries the chief's daughter. Throughout the whole film, I never felt this was a horror film. It was more reminiscent of a drama, like A MAN CALLED HORSE, which I liked better. Ivan Rassimov is pretty good as the photographer, but it is Me Me Lai as the chief's daughter who is memorable and great. I have always been a Me Me Lai fan ever since her breathtaking performance in JUNGLE HOLOCAUST and she is never given credit for her acting chops because she hardly speaks in her films. She is still very talented and charming. Lots of real animal mutilation is the one thing about DEEP RIVER that could make it a horror film, but even that doesn't execute well.
THE MAN FROM DEEP RIVER is good to see for those who want to see what started the cannibal subgenre, but as an entry in the genre, is easily eclipsed by Deodato's entries and even Lenzi's own later entries. Recommended only for completists and Me Me Lai fans.
