The Beast from 20,000 Fathoms

This film is not only a great science fiction film, but it is also one of the most influential as well. Within a few years of its release, giant monster films began to pop up from every major studio. Everything from giant ants, tarantulas, praying mantises and gila monsters began to pop up all over the place. But, perhaps its biggest influence was felt in Japan. This film is often sighted as being the main inspiration for Gojira (Godzilla). This film is defintely a classic.
