Bad acting and blatant rip-offs abound in this bootleg shark movie from Italian exploitation film virtuoso Bruno Mattei (using the pseudonym William Snyder here). Billed as Jaws 5, this is an unauthorized movie that *ahem* borrows heavily from the Great White franchise, but is nowhere near being an official sequel. In other words, this flick is straight jackin' footage, dialogue and plot from various other shark movies. But what this has that the other films don't is a Hulk Hogan look-a-like and a vicious bite of the Stars Wars theme for its closing credits.
