The Monster That Challenged the World

The magazine and story told in this movie are real and true. When Dr. Jess Rodgers (Hans Conried) is explaining how it is possible that the Monsters came into existence suddenly in the Salton Sea, he shows a Life Magazine dated October 17, 1955. This magazine actually had an article about fresh-water shrimp that suddenly appeared in a once-dry Mojave desert lake. David Duncan had read the article when it was first published and used it as the basis for his screenplay.

Despite the divers going deeper and deeper (from 65 to 125 feet), the amount of light underwater never diminishes; in fact, it actually gets brighter.
