I don't think there are any others really apart from Jaws and open Water and Deep Blue sea, well none as good anyway, they are pretty dated now (especially Jaws) but classics!!
Ptssshh!!! Blood Surf Blue Demon Cyclone Dark Waters Hammerhead Megalodon Night of the Sharks Raging Sharks Shark Attack Shark Attack 2 Shark Attack 3: Megalodon SHARK! Shark Hunter Shark Zone She Gods of Shark Reef Spring Break Shark Attack Twelve Days of Terror All fantastic movies featuring sharks...
I don't like these movies these days.. I used to like them some six-eight years before when i used to watch WWF and believed that Undertaker actually had 9 lives...
