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 »

Goofs

Just prior to being attacked the lock keeper's shirt is obviously wet from a previous take. See more »

Prehistoric Mollusks Are Creepy!
22 April 2004 | by (USA) – See all my reviews

Following an earthquake under the Salton Sea, killer mollusks make their way to the surface and make the locals part of their diet. This film is much better than what most fans of 'creature features' might suspect. The mutated mollusks really do have that creepy look to them and the cast seems to take their roles rather serious. Tim Holt, who was better known as a 'cowboy' from the early days of film is Commander John Twillinger and while rather short and stout, he hardly fits the bill of a lead, but does a nice job with this role. Audrey Dalton plays his love interest and Hans Conried is the scientist attempting to help the Navy destroy these beasties. This really is a fun film and trust me, there are far worse things you could watch and this film is really enjoyable.

This film was actually based on a true story!
