The Tv movie about a freak storm that rains killer sharks on Los Angeles became a phenomenon when it debuted last year (13) and stars Tara Reid and Ian Ziering have already signed on for a New York-based follow-up.
They will be joined by Osbourne, MCGrath, Vivica A. Fox, Andy DICk and Judd Hirsch, according to Deadline.com.
Reports suggest MCGrath will play the brother-in-law of Ziering's character Fin, while Osbourne has been cast as a flight attendant.
Returning to his Tv roots in Taxi, Hirsch will portray a cab driver in Sharknado 2: The Second One.
Filming is scheduled to start later this month (Feb14) and the sequel is expected to hit Tv screens this summer (14).
