The Curse -- YouTube - Full film (Flash)

A Caribbean resort is suddenly besieged by the ravenous fish as the result of a government experiment. A diving instructor and a biochemist seek to destroy the mutations and save the resort and the tourists from the murdering creatures.

When the bodies of several dead swimmers and divers begin washing ashore, a seaside town is thrown into a panic. A giant octopus is responsible, and Dr. Ned Turner (John Huston) thinks that its appearance may be related to the construction of an undersea tunnel. And even though an upcoming sailing competition may endanger the lives of countless people, local authorities are hesitant to keep anyone out of the water.

A prehistoric octopus of monstrous proportions, stirred from its sleep in the North Sea by underwater explosions, migrates to the U.S. Gulf Coast and menaces a seaside community. A scientist turns his trained killer whales against the octopus, and the giant sea creatures battle to the death.
