One of the film's most dangerous effects mishaps occurred during the attempt to stage the destruction of the giant spider. The effects crew covered the spider prop with gunpowder and assigned a crew member to ignite it with matches. The device stubbornly refused to fire: even after the entire matchbox had been used, the prop remained intact. Director Bill Rebane finally decided to abandon the shot, apparently assuming the effect had failed. The decision came too late. Immediately after the crew stopped trying to ignite the spider, the prop suddenly exploded, catching two crew members in the blast and inflicting severe burns. Both injured workers had to be taken to a hospital. The accident was especially grimly ironic because the production had already been operating under the hazards and improvisations of a six-week, approximately $300,000 shoot, with practical creatures, pyrotechnics, and limited resources standing in for a conventional effects department. The incident did not become a fatal catastrophe, but it was a genuine on-set injury and a vivid reminder that the film's homemade monster spectacle carried real physical risks.
