How Do You Know? (aka The Untitled James Brooks Project) filmed in Philly on July 13th. Here are a couple pictures from the shoot. You can see Paul Rudd, Jack Nicholson and Kathryn Hahn filming an office scene through the window. Reese Witherspoon and Owen Wilson also star in the film. (Thanks so much to HughE @ PhillyChitChat.com for providing the pictures!)
