The Beast from 20,000 Fathoms is a 1953 science fiction film directed by Eugène Lourié and stars Paul Christian, Paula Raymond and Cecil Kellaway with visual effects by Ray Harryhausen. The film is about an atomic bomb test in the Arctic Circle that unfreezes a hibernating fictional dinosaur, a Rhedosaurus, that begins to wreak havoc in New York City. It was one of the first monster movies that helped inspire the following generation of creature features, coining it with the atomic age.
