Kingdom of the Spiders is a 1977 American science fiction horror film directed by John "Bud" Cardos and produced by Igo Kantor and Jeffrey M. Sneller.

Part of the eco-horror subgenre,[4] Kingdom of the Spiders centers on a rural town in Camp Verde, Arizona which lies in the migration path of a horde of tarantulas turned aggressive due to pesticides having depleted their normal food sources.

Colby shows Hansen and Ashley a massive "spider hill" he recently found on a back section of his farmland, which is filled with tarantulas.

Ashley protests that pesticide would be at best a short term solution, since other spiders will continue to use the same migration path to find more food, and that the town should bring in birds and rats (tarantulas' natural enemies) to balance the ecosystem.

Once airborne, the pilot is attacked by tarantulas, causing him to fly wildly, spraying the residential areas of the town with toxic pesticide, and finally crash.

Hansen pries off the boards from one of the lodge's windows, and discovers the building, along with the entire town of Camp Verde, is encased in spider silk cocoons.

He found the film was filled with both unintentional silliness and genuinely intense scenes of horror, and said the DVD's bonus features are highly entertaining.

Shatner told Fangoria in 1998 that he was working with Cannon Films in the late 1980s to produce a sequel, titled simply Kingdom of the Spiders 2.

The actor claimed that he supplied the film's premise, which would have featured a man being tortured by his enemies, preying upon his intense fear of spiders, to get him to reveal a secret.

Cannon went so far as to take out a full-page advertisement in Variety magazine announcing that Shatner would direct and star in the film, but the studio went bankrupt before production could begin.

In 2003, the website for Port Hollywood, a film production company run by Kantor and Howard James Reekie, posted a brief synopsis of the plot of another proposed sequel, to be titled Kingdom of the Spiders II, suggesting that the villainous spiders would this time be driven to attack humans due to secret government experiments involving extremely low frequency (or ELF).
