Richard Harris, God love him, RIP, but he must have needed more booze money at that point...An awful and obvious Jaws ripoff riddled with cliches. Harris hates whales and kills a pregnant orca so her mate turns into a  Charlie Bronson whale bent on revenge, nobody listens to the sage advice of the Native American actor who played 'Chief' in "One Flew Over the Cuckoo Nest, the killer whale bites off  Bo Derek's leg, attacks the crew, kills Harris and at the end Charlotte Rampling stands around looking  bewildered and stoned. A real turd of a movie.

This was essentially a Moby Dick ripoff.
