Natural horror is a subgenre of horror films that features natural forces, typically in the form of animals or plants, that pose a threat to human characters. Though killer animals in film have existed since the release of The Lost World in 1925, two of the first motion pictures to garner mainstream success with a "nature run amok" premise were The Birds, directed by Alfred Hitchcock and released in 1963; and Jaws, directed by Steven Spielberg and released in 1975. Following Jaws, numerous horror films of a similar narrative were produced, including Grizzly (1976), Piranha (1978), and Alligator (1980).
