The Beast from 20,000 Fathoms (aka The Monster from Beneath the Sea) is a 1953 American black-and-white science fiction monster film from Warner Bros., produced by Jack Dietz and Hal E. Chester, directed by Eugène Lourié, and starring Paul Christian, Paula Raymond, Cecil Kellaway, and Kenneth Tobey. The film's stop-motion animation special effects are by Ray Harryhausen. Its screenplay is based on Ray Bradbury's short story "The Fog Horn", specifically the scene where a lighthouse is destroyed by the title character. The storyline concerns a fictional dinosaur, the Rhedosaurus, which is released from its frozen, hibernating state by an atomic bomb test in the Arctic Circle. The beast begins to wreak a path of destruction as it travels southward, eventually arriving at its ancient spawning grounds, which includes New York City. The Beast from 20,000 Fathoms was one of the first monster movies which helped inspire a generation of creature features.
