Domande frequenti

Nineteen "Semester at Sea" students on an educational vessel, the Sea King, led by Professor Franklin Babish (Charlie O'Connell) and his wife Anne (Carmen Electra), along with three crew members, are forced to take shelter on a deserted island (which is repeatedly, incorrectly referred to as an atoll) after the hull of their boat is damaged by a dead megamouth shark when its body gets lodged in the boat's propeller. The island looks like an ideal place to spend 24 hours while Captain Laura (Morgan Thompson) repairs the damage, until it becomes apparent that the island is sinking into the ocean, and a huge, two-headed shark is patrolling the waters.

2-Headed Shark Attack was filmed from a story by Edward DeRuiter, and a screenplay by H. Perry Horton.

Polycephalic (two-headed) animals are rare but not unheard of. There have been two-headed turtles, snakes, sheep, dogs, cats, etc. They are formed in the same way that conjoined twins are formed—when monozygotic twins fail to separate into two independent organisms.

With the island sinking into the ocean, the water closing around them, and the two-headed shark hunting them, the last three survivors—Kirsten (Corinne Nobili), Kate (Brooke Hogan), and Paul (David Gallegos)—make a last ditch attempt to kill the shark by rigging up a gas barrel as an explosive. Kate swims out to attract the shark by dripping blood in the water from a wound on her hand, while Paul and Kirsten try to light the fuse, but it won't catch. Kirsten grabs the barrel and swims out with it, pounding on the metal, trying to lure the shark away from Kate and Paul. When the shark takes off after her, she explodes the barrel, killing herself and taking out one of the shark's two heads. When the remaining one-headed shark turns on Kate and Paul, Kate notices the dinghy nearby, starts up the outboard motor, and jumps off as the boat heads out to sea, the sound of the motor attracting the shark. The shark takes off after the boat and attempts to bite the propeller. The dinghy explodes, taking the shark with it. In the final scene, Kate and Paul crawl out of the water onto some rocks as a helicopter approaches to rescue them.
