David Hasselhoff Promises ‘Sharknado 3’ Will Be the ‘Worst Movie You Have Ever Seen’

“The last shot is of me on the moon saluting,” says the actor, who hams it up in the Syfy sequel

If you thought “Sharknado” and “Sharknado 2” were bad, you ain’t seen nothing yet — and that’s coming from one of the film’s stars.

“You know, it’s the worst movie you have ever seen,” David Hasselhoff said on HuffPost Live on Monday, describing his “chunky part” in the Syfy sequel.

“I’ll tell you, I had so much fun making the movie,” Hasselhoff said. “The people who make the movie have such a great sense of humor. Everybody’s in on the joke, and it is so much fun. I’m telling you this thing is gonna go on forever.”

Hasselhoff is set to play Fin’s (Ian Ziering) dad, Gilbert Shepherd, in the over-the-top fishy tale. The former “Baywatch” star will join Ziering, Tara Reid and Cassie Scerbo in the movie, which sees sharks causing mass destruction in Washington, D.C., before roaring down the Eastern Seaboard and into Florida.

“I came in and played him very real,” the “Knight Rider” actor said. “So you get a very emotional father and Fin at the very end — and it just really worked, because if you play it real, with all the crazy, stupid shark stuff going on, it really works.

“The kids’ll watch it because they think it’s real, and the adults will watch it because they’re in on the joke. It’s just a perfect scenario.”

Hopefully without giving too much of the ending away, Hasselhoff revealed, “The last shot of me is me on top of the moon [saluting]. I said [to the director], ‘Are you gonna kill me?’ And they said, ‘No, you’ll be in ‘Sharknado 4.'”

We can hardly wait.

Cameo roles include Mark Cuban as the President of the United States; Ann Coulter as the Vice President; Michele Bachmann as herself; Jerry Springer as Mr. White, a manic tourist; Washington Redskins tackle Tom Compton as a reporter; *NSYNC member Chris Kirkpatrick as a pool lifeguard; and Chris Jericho, who will portray Bruce the roller coaster ride operator.

When it aired last July 30, “Sharknado 2: The Second One” became Syfy’s most-watched original movie ever.

“Sharknado 3” premieres July 22 at 9 p.m. ET on Syfy.
