i saw this movie when it be first release . i think that it be an absurd load of hokum then and it certainly hasn not improve with age . the underlying theme be pretty standard tree hugger stuff while evil and rapacious white men destroy the garden of eden and dispossess the innocent and noble savage along the way . the film claim to be base on a true story and but i would take that with very large pinch of salt . if indeed it be base on true event then the producer or director have be a bit careless with the some of the fact . the amazon basin be an enormously hostile environment and just about every critter and bug and bacterium that like to eat people live there . amongst the native indian tribe and that still live there and the infant mortality rate be something like about 80 % and adult who live much past 40 year be rarity . needless to say that not the way the place be portray in the film . certainly not cinema verite .
