Trivia

In the laboratory, above the filing cabinets on the right was an aerial picture of the K-25 plant, it was the largest building in the Manhattan Project and was authorized in late 1942. It was 11 miles from the WWII "secret city" of Oak Ridge, TN. The plant was intended to produce enriched uranium. The photo on the left appears to be a close-up of K-25. See more »

Above par monster on the loose programmer.
17 February 2001 | by youroldpaljimSee all my reviews

I found this film about giant snails on the loose in the Salton sea area slightly better than most programmer monster films of the late 1950's. The giant snails are a believable menace in that they are presented as no more dangerous than any other large aquatic predator such a shark or crocodile. They put a fight but can be killed with several well aimed shots from a pistol or a heavy axe. The real danger as pointed in the film, is that snails are extremely fecund, and if they were to enter the ocean , they could reproduce in enormous numbers thus creating ecological havoc. Anyone who has ever had a fish tank knows once you introduce one tiny snail, in a matter of couple of weeks you have hundreds. One odd aspect everyone seems to comment on is that snails look like caterpillars in snail shells. There is a type of aquatic insect larva that uses a discarded snail shell as armour, much like a hermit crab does. Perhaps someone involved with the film had seen these insect larvae and mistook them for snails.
