Even though Sharknado became a social-media sensation and summertime pop-culture touchstone, it’s admittedly not a career high point for star Ian Ziering, who reveals the only reason he agreed to appear in the made-for-TV shlock-horror flick was to maintain his Screen Actors Guild health insurance for his two young daughters, six-month old Penna and two-year-old Mia.

“I had to do it,”; the former Beverly Hills, 90210 star tells ABC News, pointing out that he didn’t actually know much about the independent movie he was signing on for.

“I was really apprehensive,”; admits the 49-year-old actor, whose wife, Erin Kristine Ludwig, recently gave birth to their second child in April. “But as an actor I get my insurance from the Screen Actor’s Guild by union, and you have to make so much [money] every year to get that type 1 insurance. Halfway through the script, I said to my wife, ‘Honey, I don’t know about this.’ She didn’t miss a beat, she said, ‘Look, you’re going to have two babies [by] this spring, you need to go to work.'”;

The unexpected success of Sharknado, Ian admits, took him by surprise, and he says he could be appearing in the already-greenlit sequel slated for summer 2014.

“We’re in talks right now for the second one,”; he says. “I hope we are able to come to terms, it would be a lot of fun. As of now, I don’t think they have a script. I know they want to shoot it in Manhattan.”;
