Near the Arctic Circle, an atomic bomb is detonated. This fearsome experiment disturbs the sleep of a giant rhedosaurus encased in ice over 100-million years and sends it southward on a destructive, deadly rampage!

The Beast from 20,000 Fathoms is a film of firsts. It spawned a new era of atomic-age creature features. It was the first screen adaptation of a work by fantasy fiction titan Ray Bradbury. And it marked the first time Ray Harryhausen had total control over special effects. He came up with a fantastic creature (constructed at full scale, all 50 tons of it) that swims down from the north to run amok through New York City before being conquered in a spectacular Coney Island roller-coaster finale. Take a classic ride. Unleash The Beast.
