Revenge of the Creature is the first sequel to Creature from the Black Lagoon. The film is notable for being the only 3-D film to be released in 1955 and the only 3-D sequel to a 3-D film. The movie was released May 11, 1955, in the United States. It was followed by a sequel in 1956, The Creature Walks Among Us. In 1997, it was aired as an episode of the comedy series Mystery Science Theater 3000, which mocked the film. The film features an uncredited Clint Eastwood, in his first screen appearance.
Having survived being riddled with bullets at the end of The Creature from the Black Lagoon, the Gill-man is captured and sent to the Ocean Harbor Oceanarium in Florida, where he is studied by animal psychologist Professor Clete Ferguson and ichthyology student Helen Dobson. Helen and Clete quickly begin to fall in love, much to the chagrin of Joe Hayes, the Gill-man's keeper. The Gill-man takes an instant liking to Helen, which severely hampers Professor Ferguson's efforts to communicate with him. Ultimately, the Gill-man escapes from his tank, killing Joe in the process, and flees to the open ocean. Unable to stop thinking about Helen, he soon begins to stalk her and Ferguson, ultimately abducting her from a seaside restaurant where the two are at a party. Clete tries to give chase, but the Gill-man escapes to the water with his captive. Clete and the local law enforcement must now try to track down Helen and her amphibious abductor.
