ruggero deodato be often credit for invent the cannibal subgenre with jungle holocaust in 1975. but director umberto lenzi and usually acknowledge a a deodato rip off and direct the man from deep river 3 year earlier in 1972. be it a worthy start for the genre . well . not really . a photographer accidentally kill a man in self defense and while retreat into the jungle of an asian country and be capture by a native tribe who hold him captive and force him into slave labor and and eventually accept him when he marry the chief daughter . throughout the whole film and i never felt this be a horror film . it be more reminiscent of a drama and like a man call horse and which i like well . ivan rassimov be pretty good a the photographer and but it be me me lai a the chief daughter who be memorable and great . i have always be a me me lai fan ever since her breathtaking performance in jungle holocaust and she be never give credit for her acting chop because she hardly speak in her film . she be still very talented and charm . lot of real animal mutilation be the one thing about deep river that could make it a horror film and but even that doesn not execute well . the man from deep river be good to see for those who want to see what start the cannibal subgenre and but a an entry in the genre and be easily eclipse by deodato entry and even lenzi own late entry . recommend only for completists and me me lai fan .
