Sharks + tornadoes = a television force that will never be stopped.



After the improbable success of both "Sharknado" and "Sharknado 2: The Second One," Syfy has been swimming forward with another sequel in the TV movie franchise. Now, it has an official subtitle - "Sharknado 3: Oh Hell No" - and a release date of July 22.



The "Sharknado" series falls firmly into the category of "so bad it's good" movies, and has clearly struck a nerve in audiences. The second installment was Syfy's most-watched original movie ever.



Stars Ian Ziering and Tara Reid return, and are joined this time by David Hasselhoff and Bo Derek as their characters' parents. "Sharknado 3" is set on the Eastern seaboard, from Washington, D.C. to Florida. Quite a few celebrities and politicians will make cameos, including Mark Cuban as president of the United States, Ann Coulter as the vice president, and Michele Bachmann as herself.
