This seems to be a long lost relic from Hammers 60's opus. Here in Oz I have seen it on tv twice, since 1978! And once in the UK in the 90's.It has it's own particular niche. Nowhere near 1,000,000 years bc in terms of, well, everything, but much more entertaining than "Creatures the world forgot". The SFX are adequate at best, the plotline absolutely insane and the dialogue may have been improved by using mere grunts, instaed of 4 or 5 "words" meaning anything you damn want them to.The great attraction is of legendary status. Victoria Vetri, Magda Konopka, Immogen Hassel and swarms of other 60's dolly birds in their amazingly well constructed fur bikinis. I have had shoes that didn't fit as tight!All in all, a good flic for a cold nights viewing.
