Ken Curtis, former singing cowboy and Gunsmoke's Festus, joined right-wing radio's Gordon McLendon in producing this hilariously bad monster movie about a horde of outsized rodents run amok on an isolated island. The creation of mad scientist Baruch Lumet (father of acclaimed director Sidney Lumet), the monster shrews (portrayed by collies in goofy rubber masks!) escape the lab during a hurricane and devour nearly every other animal on the island before seeking human prey -- including star James Best and girlfriend Ingrid Goude (1957's Miss Universe), who are stranded on the island by the same storm. The survivors manage to escape to safety thanks to some goofy contraptions constructed from trash cans. This one is best remembered by bad-film buffs for its tail-wagging canine stars and a multitude of famous names on both sides of the camera. Curtis and McLendon's companion film The Giant Gila Monster is slightly less ridiculous.
