Production crews for the new “Ghostbusters” film invaded the Upper West Side — leading devout Jews to fear that their cars were going to be towed precisely when their religion barred them from driving.

“I thought it was very disrespectful,” neighbor Lisa Berger, who is Jewish, said of the “NO PARKING, FILM SHOOT” placards that sprouted up on posts near her car, parked at West 103rd Street and West End Avenue.

The placards gave the project name as “Flapjack,” but a distinctive, ’80s-era Cadillac hearse, tricked out with a Ghostbusters logo and rooftop “Ecto Vac,” had been parking nearby.

The whole neighborhood knew “Flapjack” was just the code name for the female-focused reboot, said Berger, who saw the no-parking placards just before sundown on Sunday, “which is when Rosh Hashanah starts.”

The placards were posted for several blocks and bore the seals of the Mayor’s Office and the NYPD. They read, “VEHICLES MUST BE MOVED” by Monday night, in time for a Tuesday shoot.

“That’s right in the middle of the holiday,” said Berger, 60, who runs a cancer charity.

“I was like, you’ve got to be kidding me. You’re asking me to move my car?”

She added, “They would never do this on Christmas Day.”

Three blocks down West End Avenue, at the Congregation Ansche Chesed synagogue, worshippers were left to wonder if their cars were going to vanish like the old year — or at least get slimed.

“I’m very grateful that we didn’t come out after Rosh Hashanah to discover that all our cars were missing,” said Rabbi Jeremy Kalmanofsky.

“It would be like, ‘Who by water, who by fire, and who by missing car?’ ” the rabbi quipped, giving a twist to the manners of death Jews pray will not befall them in the new year.

Turns out their concerns were for nothing. Despite the frightening placards, the “Ghostbusters” production crew never actually had the authorization to tow anyone, according to a spokeswoman for the Mayor’s Office for Media and Entertainment.

“The production never requested the NYPD to tow cars,” said spokeswoman Marybeth Ihle. The placards had also been posted Friday morning, she added, “in order to give residents ample time to move their cars.”

A spokesperson for the production declined to comment.

The new “Ghostbusters” is due out next year, with Melissa McCarthy, Kristen Wiig, Leslie Jones and Kate McKinnon as the phantasm-blasting foursome.
