Bug (1975 film)
Bug is a 1975 American horror film in Panavision, directed by Jeannot Szwarc and written by William Castle and Thomas Page, from Page's novel "The Hephaestus Plague" (1973). It was the last film Castle was involved in before his death in 1977. The film starred Bradford Dillman, Joanna Miles and Richard Gilliland. Plot. An earthquake releases a bunch of mutant cockroaches that can create fire by rubbing their cerci together. Eventually, most of the bugs die because they cannot survive in the low air pressure on the Earth's surface, but a scientist, Professor James  Parmiter (Dillman), keeps one alive in a pressure chamber. He successfully breeds the mutant cockroach with a modern cockroach, creating a breed of intelligent, flying super-cockroaches. Production. The living room and kitchen sets from "The Brady Bunch" were reused in this film, although the living room set was rearranged slightly to a smaller footprint. Aside from a paint job, the kitchen set was otherwise unaltered.
