Andromeda (mythology) queen for her arrogance, Poseidon, brother to Zeus and god of the sea, sent a sea monster named Cetus to ravage the coast of Aethiopia including the kingdom of the vain queen. The desperate king consulted the Oracle of Apollo, who announced that no respite would be found until the king sacrificed his daughter, Andromeda, to the monster. Stripped naked, she was chained to a rock on the coast. Perseus was returning from having slain the Gorgon, Medusa. After he happened upon the chained Andromeda, he approached Cetus while invisible (for he was wearing Hades's helm), and killed the sea
Monster from the Ocean Floor was sold to Lippert Pictures for $110,000. Gene Corman later said that Lippert renegotiated his deal on the film once he found out that Roger Corman had not spent $100,000 on making it, but considerably less. Corman received a $60,000 advance for "Monster", which enabled him to make his next film. The film grossed $850,000. "TV Guide" found the movie lacking and criticized the directing; however, it found the movie interesting historically as the "beginning of something big and cheap". Variety was kinder, calling the movie a well made quickie. Monster from the Ocean Floor Monster from the Ocean Floor
