Frogs is a 1972 horror film directed by George McCowan. The film falls into the ecohorror category since it tells the story of an upperclass U.S. Southern family who are victimized by several different animal species, including snakes, birds, and lizards, as well as the occasional butterfly. Nature, the movie suggests, may be justified in exacting revenge on this family because of its patriarchs abuse of the local ecology. The film was theatrically released on March 10, 1972.
Early the following morning, Michael Crockett sets out to check on a downed telephone line. He discovers that the phone connection is dead but, before he can return home, he for an unknown reason begins shooting at birds who arent aggressive whatsoever. Aiming to scare off the intimidating avian menace with gunfire, he accidentally shoots himself in the leg and is rendered immobile beneath a tree which is almost completely covered with an strangelycolored, lowhanging moss. To Michaels horror, a horde of tarantulas descend from the branches and begin to swarm over him. With their fangs piercing his flesh, the strange moss seems to attack him also, binding him tightly as the spiders paralyzing venom overwhelms his nervous system. From within the cocoon of webbing and moss the tarantulas begin to feed.Back on the estate, Jasons sister, Iris, sends her son, Kenneth, into the greenhouse to collect flowers for a centerpiece. As he gathers up the flowers he fails to notice the dozens of large, black lizards entering behind him. The lizards swarm over the stacked shelves, knocking over numerous jars of powerful chemicals, startling Kenneth. In his panic he falls into the shelves, sending further bottles of noxious compounds crashing to the ground. The pungent liquids quickly coalesce into a lethal gas, and Kenneth is asphyxiated by the toxic cloud. ........
