'Sharknado 3' trailer features Mark Cuban, as POTUS, firing at sharks falling from the sky

Our first peek at what Mark Cuban looks like as a U.S. president ... and he's carrying a shotgun.

Cuban pretty much has to be armed. Going by Syfy's Sharknado 3: Oh Hell No! trailer that was released Thursday evening, packing heat will be practical when a shark-infested storm hits Washington, D.C., on July 22.

In the 20-second trailer, Cuban is firing at what we have to assume are sharks falling from the sky. Ian Ziering, who returns to play Fin, is ahead of him, firing automatic weapons maniacally into the air. Seconds later, Cubes and Ziering do the obligatory slo-mo stride with guns at the ready.

For this he took acting classes? "In acting you have to use the exact opposite side of your brain and let everything go," he told GuideLive's Chris Vognar.

In an email, Cuban said "that it was an opportunity to have fun and be part of a movie that has taken the nation by storm .. (get the pun?) :)"

The trailer also includes a shot of a shark landing in the lap of the Abe Lincoln statute at the Lincoln Memorial.  The first two Sharknado movies were loaded with cameos and the third includes Ann Coulter, Bo Derek, David Hasselhoff and Michelle Bachmann.
