I’m getting a lot of emails on who is filming at City Hall in Philadelphia this week. According to Michael Klein’s column INQlings , where my photos appear every Sunday, Jack Nicholson and Paul Rudd went before the cameras at the Widener Building across from City Hall last week. They’re playing father and son in the untitled James L. Brooks comedy shooting here till October. (Nicholson and Rudd shot a scene with Kathryn Hahn.) The production is working out of soundstages at the Armory at Drexel University and near Philadelphia International Airport. This week, expect to see exteriors being shot near City Hall. Star Reese Witherspoon is expected to arrive midweek for her work as a woman torn between Rudd and Owen Wilson. And another casting call has been announced: Producers need “foreign diplomats” – men and women, all ethnicities, ages 35 to 60, who own their own national dress (such as saris, kufi caps, kaffiyehs, thawbs and turbans). Heery Casting asks applicants to e-mail photos of themselves wearing the costume to howdoyouknowcasting@gmail. com. Include your phone number.
