this be simply a classic film where the human voice come from the animal be really what theyre thought be . i do not know whether my video copy have a scene miss but it never show how the dog get out of the pit . it also show an animal survival instinct and track ability . put human in the same position ant the helicopter would be out . for once an original film be improve by a remake a the voice over for the first have be remove . only the use of animal can work in a film of this kind because use people would have have to spice out the story by turn it into murder and proving that and after all and animal be more interesting than people .
