Sharknado 3: Oh Hell No! premieres Wednesday on Syfy, featuring something no one is likely to have seen before -- sharks in space!

WATCH: On Set With Ian Ziering, Bo Derek and a Pregnant Tara Reid

In the third installment of the Sharknado series, star Ian Ziering is saving Washington D.C. and President Mark Cuban, and ET's Jason Dundas got the scoop straight from the set.

"The White House is definitely not going to be OK," Ziering said. "The is Sharknado. We leave rubble in our path."

Syfy's popular Sharknado movies have done wonders for the network. The sequel, Sharknado 2: The Second One, drew an impressive 3.9 million viewers in July 2014, making it Syfy's most-watched original movie ever. These numbers were up 180 percent versus the 2013 premiere of the original Sharknado, which scored 1.4 million viewers.

VIDEO: Is a Sharknado Actually Possible?

The movies have done so well that they have stars lined up to be a part of it. Sharknado 3 features appearances by Ann Coulter, Jackie Collins, Bo Derek and David Hasselhoff in addition to billionaire Cuban.

"Producers got a hold of me and said, 'We've got this role we'd like you to play,'" Cuban said. "I was like, 'I don't want to do a cameo. It has to be real acting - real scenes, real shooting and real killing sharks.' They were like, 'Done!'"
