well and this wouldn not have be an outstanding movie if this have be one of the last z movie to be release on french screen . it be just before the cinema crisis in 1985 86 and a crisis which put an end to all these poor quality product . this film release in france under the title of prisoner in the valley of the dinosaur be a mixture of adventure ( indiana jones be quite popular then ) and erotica and cannibalistic violence . of course and none of these movie genre be successfully adapt . it just another curiosity for bad movie buff .
