The 39-year-old actress and 51-year-old actor discussed the TV movie with WGN 9 ahead of the film's July 22 premiere on the Syfy channel. Reid and Ziering starred as April and Fin Shepard in Sharknado and Sharknado 2: The Second One, and will reprise the characters in the sequel.
"It's so fun shooting these movies," the actor said. "I'm also a fan of the genre, so I like watching them as well. I get it, I understand now why they're so successful, because it's just a good, fun movie. It's kind of like it started its own genre -- the fun movie."
Sharknado 3: Oh Hell No is set in Washington, D.C., and co-stars Cassie Scerbo, David Hasselhoff and Bo Derek. Both Sharknado and Sharknado 2: The Second One proved surprisingly popular with audiences -- the latter is the most-watched TV movie to air on Syfy,
"All the time, I'm thinking, 'How am I going to pull this off? How am I going to say this dialogue? You've got to be kidding me,'" Reid admitted to Fox News. "It's ridiculous, and I have to take it seriously. But somehow it works."
"It's over the top, but it's over the top in a great way, and I've stopped questioning it," Ziering added to The Hollywood Reporter. "These movies are rated awesome, and they're not intended for overthinkers ... It's a campy, cheesy science-fiction movie, and it's wildly absurd."
Sharknado and Sharknado 2: The Second One debuted to audiences of 1.37 and 3.9 million, respectively. Sharknado 3: Oh Hell No will premiere Wednesday at 9 p.m. ET, and also features appearances by Mark Cuban, Ann Coulter and Michele Bachmann.
