Orca: Killer Whale

One of umpteen attempts to cash-in on the success of Jaws (qv), mixing horror and thrills with an ecological theme as a killer whale takes revenge for its mate's death off the Newfoundland Coast.

All the performances are incredibly ropey, particularly Richard Harris who appears to ape Long John Silver with his role as a marine expert, although considering how bad the script is, it's a surprise any of the actors managed to deliver their lines with a straight face.
