Scientists track a prehistoric monster in the South American jungle while it tracks them. The explorers capture the mysterious creature, but it breaks free. The Gill-Man returns to kidnap the lovely Kay, one of the scientists, with whom it has fallen in love.
“Interestingly enough, Creature from the Black Lagoon was inspired by a Mexican folk tale. Producer William Alland recalled (in Tom Weaver's collection of interviews, Monsters, Mutants and Heavenly Creatures) a dinner with Orson Welles, Dolores Del Rio, and Mexican cinematographer Gabriel Figueroa in which the latter described 'this creature that lives up in the Amazon.... Once a year he comes up and claims a maiden, and after that, he leaves, and the village is then safe for another year.... He [Figueroa] said, 'You people think I'm joking, don't you?' and he then insisted that this was absolutely true, that he could produce photos and this and that ... !' Fact or fiction, Alland decided to develop the idea into a movie at Universal.” —Turner Classic Movies
