BACK ON DVD! The natural beauty of Bo Derek in her screen debut and the supernatural spectacle of Dino De Laurentiis' (King Kong) masterful use of special effects on a gigantic scale highlights this rousing adventure story. It's the epic tale of one powerful being against another; a strong, determined fisherman (Richard Harris) versus an equally determined whale. When the giant whale's pregnant mate is maimed and killed by Harris, in a variation on Moby Dick, the whale seeks revenge on the man. Orca smashes boats, collapses buildings, and even manages to cause enormous destruction by fire. A suspenseful action drama.
