An atomic bomb test in the Arctic Circle awakens a long-hibernating and ostensibly extinct Rhedosaurus. Emerging from the sea, the Rhedosaurus wreaks havoc on NYC in every direction, leveling cities and amusement parks in his path. The film is based on Ray Bradbury's short story "The Fog Horn."

Critic Reviews from Rotten Tomatoes

"Despite more than a suspicion of palaver, it generates a fair portion of interest and climactic excitement ..."
‑ A.H. Weiler, New York Times
"Clumsy in some very key ways at the script level, it's nevertheless an exemplary B-picture."
‑ Tim Brayton, Antagony & Ecstasy
"Visionary from beginning to end"
‑ Fernando F. Croce, CinePassion
"Frankly, I was rooting for the monster.... Watching the beast eat a roller-coaster was especially satisfying."
‑ John J. Puccio, Movie Metropolis
"Superior giant monster opus with great effects."
‑ Ken Hanke, Mountain Xpress (Asheville, NC)
"Freed from the Arctic ice by atomic blasts, one of Ray Harryhausen's most loveable prehistoric beasts trundles down the US coast to stomp New York ..."
‑ , Time Out
"The third act - a rampage through New York comprised of stop-motion, miniatures, rear projection and other layering processes - ensures that all was worthwhile."
‑ Rob Humanick,
"...admirably stands the test of time. Despite its financial restrictions, it is a solid effort that works on all levels. Not a masterpiece, perhaps, but definitely a classic of its genre..."
‑ Steve Biodrowski, ESplatter
"The tricks are still pretty clever."
‑ , Film4
"Good old-fashioned giant monster goodness!"
‑ Scott Weinberg,
"This 50s bis Beastie movie is still a romp despite obviously dated effects."
‑ Kim Newman, Empire Magazine
"Lovable bad sci-fi film that overcomes its slight story and flat acting with wonderful cheesy special effects."
‑ Dennis Schwartz, Ozus' World Movie Reviews
"This enjoyable 'B' oldie is noteworthy not just for establishing a template for the Atomic Age Behemoth flicks that followed."
‑ Mark Bourne,
"Fun B movie classic filled with Ray Harryhausen's grand animation."
‑ Gerry Shamray, Your Movies (
