"The Beast from 20,000 Fathoms" was the first live-action film to feature a giant monster awakened/brought about by an atomic bomb detonation, preceding "Godzilla" by 16 months. During the production of "Godzilla", its pre-published story was very similar to that of "The Beast from 20,000 Fathoms" and was titled "The Giant Monster from 20,000 Miles Under the Sea" (海底二万哩から来た大怪獣 Kaiteinimanmairu kara Kita Daikaijū). As above-mentioned, Rhedosaurus was originally planned to breathe "atomic flame" similar to Godzilla's atomic breath. The film's financial success helped spawn the genre of giant monster films of the 1950s. Producers Jack Dietz and Hal E. Chester got the idea to combine the growing paranoia about nuclear weapons with the concept of a giant monster after a successful theatrical re-release of "King Kong". In turn, this craze included "Them!" the following year about a colony of giant ants (the first of the "big bug" films), the "Godzilla" series from Japan that has spawned films from 1954 to the present day, and two British features directed by "Beast" director Eugène Lourié, "Behemoth, the Sea Monster" (U.K. 1959, U.S. release retitled "The Giant Behemoth") and "Gorgo" (U.K. 1961). Harryhausen himself admitted the extensive similarities with his work and Godzilla in an interview regards Peter Jackson's "King Kong" in 2005, and expressed a bitterness towards the Japanese series. Additionally, Harryhausen's Allosaurus within the 1966 movie "One Million Years B.C." was followed by Toho's Gorosaurus in 1967 movie "King Kong Escapes" where both theropods were grey-blue colored man-eaters and surviving descendants of Allosaurus, and giant snakes and ape or ape-man appeared in both films.
