Ben Affleck and Jennifer Lopez worked into the wee-small hours of Friday, shooting a scene for the Kevin Smith movie Jersey Girl at the Queen Village landmark. It was their characters’ first date (in a Manhattan diner) and included a kiss. Between takes, though, Affleck and J. Lo could be seen getting along like a more established couple – hugging and smooching.

Affleck wore a conservative gray sports jacket, periwinkle-blue shirt and dark slacks. J. Lo, her hair short and curly, wore a sexy-yet-demure cream-colored dress. She was comfortable enough to eat fries.

They’d scooted from their trailers into Famous’ back door about 10:45 p.m, away from a knot of onlookers. They left before 2:30 a.m. No time for autographs. (Earlier Thursday, after shooting at the nearby Meredith School, Lopez obliged young fans.)

Production designer Robert “Ratface” Holtzman, a vet of Smith’s Chasing Amy and M. Night Shyamalan’s The Sixth Sense, spent nearly all day Thursday with his crew to deck out Famous in Santas and menorahs for the scene, which is set around the holidays. (Fun fact: The last time Famous reached the big screen – in 1993’s Tom Hanks-Denzel Washington-Jonathan Demme hit Philadelphia – it, too, was a warm-weather shoot set in winter.)

Smith worked hard in an untucked baseball jersey, long shorts and sneakers.

Christmas in September?

It was last night at 4th and Bainbridge as J.Lo, Ben Affleck and the crew of “Jersey Girl” took over the Famous 4th Street Deli.

On the windows were Hanukkah decals and inside were Christmas wreaths, so no need to guess when the scene takes place. Wonder why movies cost so much? More than four dozen members of the crew worked on setting the scene as they dined on roast beef, turkey, king crab legs and desserts galore in the production tent. As for the stars’ special requests, a Famous chef was asked to make french fries for Jennifer and chicken pot pies for Ben.

Finally Ben and Jen snuck into the side door of the deli from their trailers and began shooting. Affleck was dressed in an electric blue shirt with a tie and J.Lo wore a cream sleeveless slip dress.

A crowd of 150 or so fans waited outside the deli for hours to catch a glimpse, but the group had dwindled to around 50 diehards when shooting began after 11 p.m. This being Philly, at night, near South Street, toughs on motorbikes kept riding by trying to louse up the takes.
