Another big-budget monster movie from producer Dino de Laurentiis, Orca concerns the mutual revenge pact between an obsessive whaler (Richard Harris) and an angry killer whale, whose pregnant mate Harris killed. The whale strikes back by biting off Bo Dereks leg, so Harris and concerned biologist Charlotte Rampling follow it to frozen northern waters for the climactic showdown. Just in case you like Jaws better than Moby Dick, theres a killer shark thrown in for good measure. Ponderous, pretentious, and dull, this opportunistic disaster fittingly sank at the box office. ~ Robert Firsching, All Movie Guide
