There’s a potential disaster brewing at the production offices of Sharknado 3, and it doesn’t involve vengeful sea creatures or extreme weather events.

Nearly 40 members of the TV movie's post-production team voted to walk out Tuesday over contract disputes. The team of digital artists and editors are now striking outside the film’s Burbank production offices in search of health and pension benefits.

The crew operated under IATSE union contracts for the first two installments of the disaster franchise, which were popular for SyFy, but rushed production for the third installment prevented production company The Asylum from reaching a union agreement with their staff.

"We shoot this in February, we deliver it in June," said director Anthony Ferrante. "A studio movie like this would take two-and-a-half years."

Sharknado 3 star Tara Reid talked to ET on the set of the movie recently, and explained just how important post-production is for films like Sharknado, which rely heavily on special effects and CGI.

"You really don't know what the outcome of this film's gonna be until they edit it and put the sharks in," Reid said. "I have no idea what it's gonna look like until the end."
