Empire of the Ants (film)

Empire of the Ants is a 1977 science fiction horror film coscripted and directed by Bert I. Gordon. Based very loosely on the short story Empire of the Ants by H.G. Wells, the film involves a group of prospective land buyers led by a land developer, pitted against giant, mutated ants.

A heavenly paradise becomes a hellish nightmare when a toxic spill turns harmless ants into gigantic rampaging monster insects.The opening narration briefly introduces the viewer to the ant and its behavior. It takes note how ants use pheromones to communicate, and how they cause an obligatory response that must be obeyed. But humans dont have to worry about that.... As the opening credits roll, barrels of radioactive waste are being dumped off a boat into the ocean. Eventually one of the barrels washes up on the shore and begins to leak a silvery goo attractive to local ants. ........
