"People get hung up on the fact that sharks can't exist in a tornado and tornadoes can't do what they do, and all that stuff," Ferrante said in a teleconference with reporters this week.
"The simple explanation on our end is: it's a sharknado. It's like our Frankenstein, our Freddy Krueger, our Jason. You don't question Jason getting his neck chopped off half a million times and getting shot and getting back up again. It's part of the mythology.
So, I think the thing we've accepted is the sharknado is our villain and it does what we tell it to do. So, if it chews through a car hood, a shark can't do that, but a sharknado can. It opens up the imagination of what you can do and we were able to do a lot of crazy stuff because we were freed by the fact that we could do anything."
The first film was about how bar-owner Fin, played by Ian Ziering, and his ex-wife April, played by Tara Reid, survive a freak weather occurrence that deposits man-eating sharks on Los Angeles. The sequel finds the reunited couple in the midst of a similar disaster -- this time in New York City.
So, what makes the Sharknado franchise a pop-culture phenomenon?
"You can't really pick it apart and say it was this or that," Ferrante said.
"We were this fun, little film that people didn't have to pay $50 at a movie theater to take their family to. They got to watch it in the privacy of their own homes and they had a blast. They made fun of it. They loved it. They hated it. It was great."
Asked by UPI if he felt more pressure going into the second film because he now has audience and media expectations to meet, Ferrante replied, "I think there is pressure just as a filmmaker."
"I'm hard on myself. I beat myself up every day trying to pull this stuff off. You can't go into the second one and just be OK. You have to be better than OK. You have to be good, great, whatever you can do to make a better experience.
I think the benefit of what we did on this one is that we didn't have, like, three years in between making the movies. We literally blew up in July  and were talking about a sequel in August and the script was being developed and we were shooting in February. So, it felt like we were still making the first movie."
"We had a lot of discussions about the Sharknado moment," he continued, "and I kept saying I don't think we will ever be able to achieve what we did in the first movie with Fin going into the shark [and cutting his way out with a chainsaw]."
"That was lightning in a bottle, but we can provide a whole bunch of other really cool moments. So, if we could come up with 10 or 12 great moments, maybe one of them will stand out and we'll be lucky and someone will go, 'It's the new Sharknado moment.' Or maybe there is enough stuff in this, they won't even question it. They'll just have fun. It's a tricky balance, but I think we had more confidence going into this and we could take chances and risks."
Sharknado 2: The Second One is scheduled to premiere on Syfy July 30.
