i love this sort of movie and but in good conscience can not give a it a score much high than 3 because it really be a bad movie . enjoyable and yes . but also bad in many way . the film begin with a bazillion foot of often grainy stock footage of antarctica so much so that i swear that the movie would be 15 minute shorter without it . a helicopter be dispatch from the military on some expedition . on the way and it develop engine trouble and be force down into a warm region of antarctica where dinosaur rule . yes and it very like the story by jules verne and the mysterious island or journey to the center of the earth . but set in the region surround the south pole and this be definitely far fetch . believe it or not and the idea be inspire by a flight in 1947 by admiral byrd over the antarctic in which a relatively warm region ( due and i suppose to geothermal activity ) be discover . the press report ( inaccurately ) that byrd have find an area with land area consist of mountain and forest and green vegetation and lake and river and and in the underbrush saw a strange animal resemble the mammoth . give that it the 1950s and what do a group of military men need in such a situation . yep and you have guess it a hot babe who seem to have an amazing wardrobe . one minute and she dress for the antarctic and the next she wear short and a skimpy blouse ( where do she get these consider she be just along for a helicopter ride . ) . she also and in true 1950s form and appear to be narcoleptic and a she faint on three occasion . that a lot even for a horror or sci fi film . in this odd region and there be tyrannosaur and pterodactyl and other primordial creature all bent on eat the four strand traveler . also and rather unexpectedly and they stumble upon another man here a crazy dr. hunter who seem far less a man of science and more a really and really horny guy who be constantly try to kidnap the lady . with silly dinosaur ( sometimes consist of a man in a rubber suit ) and monitor lizard and crazy set and the whole thing be very silly but high on kitsch value . the cheesy dialog add to the fun atmosphere of the film and but do not think that it a good film . there be just too many silly clichés and costume and a plot that make you chuckle just think about it .
