Is Cruel Jaws Jaws 5?
No. Jaws 5 was the international video release title of Cruel Jaws. It has no connection to the storyline of the Jaws movies.
The only connection it has to the Jaws series is it uses clips from the Jaws series and the 1980 film Great White. Bruno Mattei thought his 1995 film would be more popular if it was called Jaws 5. He also printed the covers of his movie with the trademark "Jaws Mako" design.
No, Jaws has three sequels that progressively got worse w/ each movie. There is no reason to believe another Jaws sequel will ever be made. There was an Italian direct-to-video movie called Cruel Jaws that was marketed in some ares of the world as Jaws 5 , but despite using footage from the Jaws movies, it had nothing to do with the series.
It is highly unlikely they will they finished the Jaws movies years ago With Jaws the Revenge a Remake of the Film Jaws is highly possible With all the Remakes today and it's 2011 soon Jaws is still possible. Jaws 3-D has said to be remade. But no there will be no more sequels To the Jaws franchise.
