this be a very touching film and which have always fascinate me a i do have an interest in feral child . the film and base on david kendall novel lazaro and revolve around young lazaro and a child raise deep in the amazonian jungle by his mother follow the death of his priest father before he be bear . mother and son live a happy and idyllic life until gold hunter enter their territory and end up murder lazaro mother . leave to fend for himself and he be then take in by the dolphin who live in the river and protect their human charge from predator a they would their own calf . some year later and when lazaro be about ten or so and he be then find and bring to the city where his father mentor vow to care for him and make him civilised . but lazaro be more intent in revenge when he see the man who kill his mother . the act from alessandro rabelo and who play lazaro and and ajay naidu and who be cast in the role of lazaro best friend and be excellent . you can not help but grow attach to the boy and care for their plight . charles durning also give a masterful performance a the priest who just want to do right by lazaro while he have such a rapport with young rabelo and leave the audience convince of the grow bond between the two . the haunting music only add to the sense of mysticism and spirituality conjure up by the storyline of the film . where the river run black really be a one of a kind and i highly recommend it to anyone just look for something that bit different . it touch many issue and from the plight of rescue feral child ( be there a point where they should just be leave alone . ) to whether we have a right to seek vengeance when we be wrong to environmental issue ( the cut down of the rain forest ) . it a film that stay with you forever .
