Speaking of Jaws rip-offs, this fourth entry in the shark-attack series supplies soggy camp where the original brought oceanic terror, moving the action from Amity Island to the Bahamas. That is to say, a shark literally follows Ellen Brody (the returning Lorraine Gary) on a trip to visit her son Michael (The Last Starfighter’s Lance Guest), a marine biologist who’s far more excited than she is about the rare presence of a Great White in Caribbean waters. Most people rightfully remember this 1987 flick for Michael Caine’s jaunty “yes indeed, I’m doin’ this for the money” performance as a local pilot, as well as the notion that a shark both understands the concept of revenge and is capable of setting a precise compass and traveling over 1,200 miles to accomplish it.
