Cyclone (Spanish: El Ciclón; also known as Terror Storm) is a 1978 Mexican survival horror film directed by René Cardona Jr.[1] and starring Arthur Kennedy, Carroll Baker, and Lionel Stander.

The plot follows a group of passengers from a crashed airplane who find refuge on a small tour boat in the ocean, and who eventually resort to cannibalism for survival.

Once the cyclone is gone, the Mexican coast guard starts a fruitless search for the missing, and after three days they abandon hope of finding any survivors.

The next day, when Taylor, a selfish passenger from the plane, tries to appropriate some of the sparse water supply for himself, a fight breaks out, in which course the glass bottom of the boat is shattered.

As they float in the sea, sharks are attracted to the scene and devour almost half of the shipwrecked, including Taylor, before two seaplanes arrive and rescue the remaining survivors.
