Trivia

Previously an empty desert sink nearly as far below sea level as Death Valley, the Salton Sea originally formed in 1905-07 from a pre-Hoover Dam flood of water from the Colorado River. The 1931 project that created Hoover Dam (aka Boulder Dam) was the result of flood control on the river. Eventually becoming the largest lake in California, a boom town grew around the lake, with all the typical real-estate promotional development and hype, peaking in the 1950s. In the ensuing decades, as the lake slowly began to shrink, land values dropped, tourism faltered, the salinity of the water and pollution have increased, and the area has become a virtual ghost town.

Goofs

In the underwater "pool" where the creatures are supposed to reside they are shown as Monoplacophorans- meaning they have a shell like a snail. When the creature is shown out of the water in the office attack and lock attack scenes it appears as a Polyplacophoran- meaning flexible plates on the dorsal side instead the carry along shell. Only in a Hollywood movie could a creature be both types of mollusk. See more »

A quality little film
28 October 2002 | by funkyfrySee all my reviews

Fairly standard atomic monster fare bolstered considerably by a cool looking monster and a pretty good cast. Also, the script is a bit funnier than usual, without in any way being a parody or farce. It includes more characterization and human interest (in a genuine sort of way) than most such films. In this case, the military must hunt giant mollusks that supposedly can walk on land or swim in water, but we only see it in the water and sticking its head out of the water. Amusing, but dry, fun. Holt holds up well in the lead role, although the years were not kind to his midsection.
