Frogs

Frogs is a 1972 American natural horror film directed by George McCowan. The film falls into the "eco-horror" category, telling the story of a wildlife photographer who meets an upper-class U.S. Southern family who are victimized by several different animal species, including snakes, birds, leeches, lizards, and butterflies. The movie suggests nature may be justified in exacting revenge on this family because of its patriarch's abuse of the local ecology. The film was theatrically released on March 23, 1972.
