Raging Sharks

Raging Sharks is a 2005 American direct-to-video science fiction action horror film directed by Danny Lerner.

It stars Corin Nemec, Vanessa Angel, Corbin Bernsen, Todd Jensen, Elise Muller, Blinky van Bilderbeek, Simone Levin, Emil Markov, Jonas Talkington, and Atanas Srebrev.

Set in an isolated underwater research facility, the film follows a group of scientists as they discover a strange series of crystals, only to find out that it also harbors a psychological effect on sharks, causing them to become more aggressive.

Mike is forced to hide in a nearby crevice, where he finds the capsule, and retrieves another sample of the crystal before managing to return to the Oshona.

Minutes later, Mike and Linda discover Jonas to be stabbed to death, and as they return to the control center, Stiles appears and causes a shootout that kills Vera.

A Horror.Net review said that the film is a good use of live stock footage, computer effects, and fake shark heads and gallons of blood.
