It has STOLEN footage of Jaws, Jaws 2, Great White,and Deep Blood. It also has STOLEN the woodwind track from thje Star Wars theme. I amazed they called anything from this thing original! Even the dialog is lifted from movies like Jaws (it stands out...believe me!) They also keep calling the shark a tiger shark, even though it's obviously great white footage.
In the preview you'll see, the steal footage from Deep Blood, Great White, Jaws 2 and Jaws...in that order! Mind you, this is only a 45 sec preview.
