I'm no copyright expert, but I can't imagine you can just go out and make a shark movie and call the main man-eater "Jaws". If I made a spy movie and called it James Bond, I'd expect a big, fat lawsuit. How then does Jaws in Japan exist? Better yet, what the hell is Jaws in Japan?
Has Jaws become the new Ernest? Will we soon see Jaws Scared Stupid or Slam-Dunk Jaws? Where did this movie even come from? IMDb.com has no listing for the film, but Amazon is offering it for pre-order -- proof that it does exist! There's no plot synopsis (though the title itself probably does the trick), and the film appears to be from Japan. Whoever made that cover is certainly gutsy enough to play fast and loose with Universal's Jaws logo.
