Police tow trucks were busy clearing parked cars from Chestnut Street yesterday outside the Lord & Taylor store, near 13th Street. What was up? Ben Affleck and Jason Biggs, who play coworkers in the Kevin Smith film, were due to show up to shoot inside the Wanamaker Building. When queried, a worker at the building said an upstairs stairwell would look great on celluloid.

The Jersey Girl crew will be in Paulsboro, Gloucester County, today and tomorrow before taking a Labor Day break.

In other Jersey Girl matters:

Affleck and his best friend, Matt Damon, have something else in the works these days. They enjoy giving back to the film community since they were plucked from obscurity with Good Will Hunting, and are launching their second Project Greenlight filmmaking contest; this time it’s open to aspiring writers and directors, with the winners getting $1 million to make their movie. (Info: projectgreenlight.com.)

And the sight of Biggs, who stars in the American Pie flicks, ties nicely into a bit of, uh, dish: George Carlin, who plays Affleck’s father, is a major-league, don’t-spare-the-nutmeg pumpkin-pie connoisseur. We’re told that a few pies have been delivered to him for his dining pleasure.”
