Ian Ziering Has a Fist Full of Shark’s Teeth in ‘Sharknado’ Trailer (Video)

The Syfy film — which features a tornado full of angry sharks — premieres Thursday

If you're scared of sharks or tornados, then you'll probably want to avert your eyes from the trailer for "Sharknado" — because the Syfy TV movie has both.

So what, exactly, is a Sharknado? It's a tornado full of sharks, duh. And only one man can stop it. Yep, you guessed it: "90210" and "Dancing With the Stars" alum Ian Ziering.

Ziering, for one, is not going to stand around "and wait for sharks to rain down" on him. After all, he's got a city to protect — and a chainsaw.

In the trailer, Hurricane David is driving all of the sharks up north. Unfortunately, they're swimming directly in the path of a super powerful tornado. The combination is deadly, like really, really deadly.

The plan is simple for Ziering and friends: Get a helicopter, make a ton of explosive devices, fly into the tornado and bombs away! How else does one deal with a Sharknado?

"Sharknado," which also stars Tara Reid, airs Thursday at 9 p.m. ET on Syfy.

Watch the incredible trailer. And then watch it again:
