Horror Planet - Inseminoid
This unsettling British Alien clone (released in the U.K. under the sleazy title Inseminoid) is set in the labyrinthine underground caverns of a remote planet, where a team of scientific explorers find themselves in the bizarre predicament of defending themselves from a rampaging, pregnant crew member (Judy Geeson). It seems the poor woman has been impregnated by a slime-covered insectoid alien (as depicted in a surreal and truly disgusting flashback), and the resulting hormonal imbalance has transformed her into an inhumanly strong, psychopathic killer. She promptly sets about dismembering and eating everyone in sight (no doubt because of the baby's nutritional requirements) before finally giving birth to a pair of snarling little mutants bearing a more-than-passing resemblance to the terror tykes from the It's Alive series. Aside from the admittedly "unique" premise, this is a fairly standard rip-off -- complete with characters resembling their Alien counterparts -- and the lovely Geeson's rabid, eye-popping performance is more than a bit uncomfortable to watch. The American video release is missing a great deal of the original's graphic violence.
