You've got to admire Hammer films. Rather than wasting the sets and costumes left over from One Million Years B.C, they decided to make this loopy lost world film with them instead.
Hunting for a wounded leopard on an African game reserve, David Merchant(Michael Latimer)stumbles onto the land of the sacred White Rhino, and is promptly taken for sacrifice by an angry tribe, who treat him to some prime Hot Gossip moves, before dragging him into a cave where sits the statue of the fabled beast.
Feeling a bit horny, David touches up the Rhino, only for time to freeze, and a secret door to a prehistoric world opens up. Of course, being the inquisitive sort he enters, and discovers a world ruled by a tribe of shapely brunettes, lead by evil Queen Kari, played with great gusto by Martine Beswick. Blonde girls are kept as slaves, whilst men are locked in a cave, starved of light.
There are two reasons to fear for the future of this arrangement, as all the men are twenty years older than the females, and there are no children.
Kari wants David as a sex slave, he prefers blondes, and more hilarity follows, as he gets involved in local tribal politics.
Then, after much derring do, we get a 'was it all a dream?' scenario, and you'll be asking yourself the same question, after spending an hour and a bit in the company of this insane film.
4 out of 5 for sheer entertainment value
