Revenge of the Creature (a.k.a. Return of the Creature and Return of the Creature from the Black Lagoon) is the first of two Universal-International sequels to Creature from the Black Lagoon. It was the only 3D film released in 1955 and the only 3D sequel to a 3D film released during “the golden age of 3D”. Produced by William Alland and directed by Jack Arnold (the director of the first Creature film), the film stars John Agar, Lori Nelson, John Bromfield and Nestor Paiva. The Creature was played by Tom Hennesy on land, and once again, portrayed by Ricou Browning underwater. It marked Clint Eastwood’s film debut.
Revenge of the Creature premiered in Denver on March 23, 1955 and a “flat”, non-3D sequel, The Creature Walks Among Us, followed in 1956. Revenge was released as a double feature with Cult of the Cobra. Wiki
