Who knew this thing existed? There's a reason we didn't. Great White is a ripoff of Jaws so odious that the studio was able to get this movie out of theaters in two days (and prevent it from being released as home video.) Here's a description of Great White from "The Crane Shot":
The big Windsurfing Regatta is coming up, and even though one teen has already been chomped on, the mayor refuses to cancel. That leads to an amazing scene in which the shark plows through dozens of windsurfers like bowling pins, knocking them into the water one by one".
We've talked about the paucity of windsurfing appearances in movies in the past, but we were ignorant of Great White. I wonder if there are any bootlegs around.
