Unfairly dismissed on its release as a low-budget imitation of Alien (1979), Norman J. Warren’s Inseminoid follows an archaeological expedition by the space explorer Xeno to investigate the origin of a vanished civilisation on an atmospherically hostile planet.
The expeditionary team – led by Holly (Jennifer Ashley) – occupy a research facility on the remote planet and begin to explore the planet’s surface. Two of the male team members discover a mysterious tomb containing a pile of crystal-like objects which glow mysteriously.
An attempt to photograph the objects results in a shattering explosion and one of the men is killed outright. The other develops hideous sores on his face and behaves as though possessed.
Thus begins a series of horrifying adventures for members of the expeditionary team. The most unfortunate is Sandy (Judy Geeson) who goes to investigate the sinister tomb and is attacked, raped and inseminated by an alien.
When she is taken back to base, she is discovered to be two months pregnant and slowly begins to transmute into something indescribably nasty, wielding a destructive force that threatens the existence of her colleagues. They have no option but to try and destroy her before she destroys them.
Growing heavier by the hour and consumed by an unnatural bloodlust, she destroys much of the installation and cannibalises her colleagues. After giving birth to alien twins, she loses her superhuman strength and is killed by Mark (Robin Clarke), who then becomes a victim of her offspring.
Only corpses remain to greet a rescue shuttle that departs with two stowaway alien twins onboard.
Stephanie Beacham is the most competent actress on show in a largely no-name cast but look out for Victoria Tennant as one of the victims.
Shot in four weeks in Chislehurst Caves in Kent, Inseminoid was known by the catchy title of Horror Planet in the USA.
