A ferocious dinosaur awakened by an Arctic atomic test terrorizes the North Atlantic and, ultimately, New York City.

When producers Dietz and Chester were negotiating with Bradbury to rewrite their screenplay, he reminded them that both works shared a similar theme of a prehistoric sea monster and a lighthouse being destroyed. The producers, who wished to share Bradbury's reputation and popularity, promptly bought the rights to his story and changed the film's title.

The film is worth watching because of the involvement of Bradbury and Ray Harryhausen, as well as having a supporting role from Lee Van Cleef. It may not be amazing, but the effects are rather good and it is a piece of 1950s science cheese that can be enjoyed if you just suspend disbelief for an hour.

Most interesting is the alleged influence this movie had on "Godzilla". This film is semi-forgotten, or at least not widely seen. But it had a dinosaur rise following an atomic blast and then destroy a city, trampling the army and electricity in its path. Sounds like Godzilla! And indeed, this was a primary influence on the Japanese monster film, which has since become one of the most culturally important films in horror / monster history. So maybe "Beast" needs to be respected just a little bit more.
