Invitation to Hell on AllMovie

This minor made-for-TV effort from horror auteur Wes Craven is one of the oddest attempts at seriously blending supernatural horror and science fiction elements, which amounts to a muddled but amusing failure. The convoluted plot involves scientist Robert Urich's experiments with a new spacesuit designed to detect non-human lifeforms for a proposed expedition to Venus. When a sultry succubus (Susan Lucci, who was born for such a role) begins exerting her demonic influence on the members of a country club -- including Urich's wife and children -- he dons the completed suit for a literal journey into hell itself to rescue them. Craven's skill manages to elevate this loopy premise slightly above the level of pure nonsense, but low production values and the constraints of TV censorship prevent it from being adequately explored.
