Orca

The killer whale is one of the most intelligent creatures in the universe. Incredibly, he is the only animal other than man who kills for revenge. He has one mate, and if she is harmed by man, he will hunt down that person with a relentless, terrible vengeance – across seas, across time, across all obstacles. Dino De Laurentiis presents an all-star aquatic adventure that pits man vs. beast in a Moby-Dick-meets-Jaws duel to the death about an Orca seeking vengeance for the death of its mate. Richard Harris, Charlotte Rampling, Will Sampson, and Bo Derek star, while Ennio Morricone provides the rousing score.
