In all respects, Forbidden World is cheap and dreary. The action alternates from attack scenes to sexual encounters and back again with indifferent regard. Meaningless babble is occasionally thrown in to justify happenings. Logic is confusing why is a trouble-shooter called in before the creature has hatched? And why at all if people want its existence hushed up? The tiresome point-of-view shots from the creature look only like someone has smeared the camera with Vaseline, and the poor editing leaves the film sorely lacking anything approaching the masterful handling of Ridley Scott in Alien. Jesse Vint makes a resoundingly wet hero and the cheap electronic score is a major irritant. Many of the effects shots have been cannibalised from the previous New Worlds science-fiction film Battle Beyond the Stars (1980).
The film has gained a certain (undeserved) recognition on the basis of its climax where the scientist kills the alien by reaching in, pulling his cancer-ridden liver out and feeding it to the creature.
Allan Holzman only made one other genre film as director with the killer cyborg film Programmed to Kill (1985). All his subsequent work has been in documentaries.
