"I think that's going to be a big turning point for the franchise. It gives it some excitement, and it's giving the fans a chance to interact.
"No matter what happens, I'm proud to be a part of this phenomenon."
After the first two films saw a tornado of sharks hitting first LA and then New York, Sharknado 3 sees the action moving to Washington and Florida.
The made-for-television disaster film also stars Ian Ziering as Fin and David Hasselhoff as Fin's dad, as well as cameos from Jerry Springer, Bo Derek and former X Factor stars Jedward, who recorded the theme song.
The Sharknado franchise has taken social media by storm, with the first two films generating more than a billion tweets between them. Sharknado producer, Chris Regina, hopes this latest stunt will prove just as engaging.
"I'm hoping that we're going to break the internet this time with the "April lives, April dies" at the end," Regina told Hollywood Reporter.
"I think it's going to be precedent-setting. I can't think of an instance where another network has done something of that nature at the end of an event. Hopefully it's a TV first."
But despite fans' interest in the franchise, it has yet to win over the critics.
"Having now watched "Sharknado 3: Oh Hell No!" I find myself in the position of having to write about it. And I am not sure which is worse, really, or even how to proceed," said Robert Lloyd, writing in the LA Times.
