MONSTER THAT CHALLENGED THE WORLD 1957 (MGM)

Gotta love that great title!! An earthquake releases giant sea mollusks which terrorize people living around the Saltan Sea in southern California. Tim Holt is the Commandeer in charge of the Navel Base where the earthquake struck.
Some of his men are killed and then the monster starts attacking townspeople as well. The monsters are very cool looking things with large eyes and multiple legs.
Audrey Dalton is looking lovely as always. She becomes involved with Holt and their relationship is built up slowly and works well into the monster plot.
Hans Conreid is a base scientist who helps fight the monsters. Very cool and entertaining movie that monster fans should enjoy.
