The cast of the small-screen thriller will also include "Jersey Shore" reality TV personality Vinny Guadagnino. It is to debut on the cable network next summer.
"Sirico is Captain Sallie, the wise veteran of boardwalk life and lore," a synopsis said. "Scalia is Moretti, former Guido beach bum and now police chief. Sorvino portrays the possibly corrupt mayor and Atherton is the greedy developer Dolan, who wants to tear down the boardwalk to build a luxury resort where the guidos will not be welcome. Vinny Guadagnino plays the on-scene reporter Conte and Joey Fatone appears as himself.
The movie also stars Jeremy Luke as The Complication, Melissa Molinaro as Nooki, Joey Russo as Donnie, Daniel Booko as Balzac, Audi Resendez as B.J., and Alex Mauriello as J-Moni."
The movie is about how rare swarms of sharks converge on the Jersey Shore during the July 4 weekend because of illegal underwater drilling.
"Now the angry sharks are on a rampage, devouring residents and leaving it up to the locals to try and save the day," Syfy said in a news release.
