Actor Michael Imperioli politely corrected a woman who approached him calling out "Hi, Chris," after his character on "The Sopranos" Friday night outside around Rittenhouse Square. "It's Michael, how you doin," he asked our tipster. Imperioli, in town shooting Peter Jackson's "The Lovely Bones," was seen at Barnes & Noble and Bello (131 S. 18th), a mens clothier. Imperioli graciously chatted with a good number of fans who recognized him. He plays Len Fenerman in "The Lovely Bones," based on Malvern native Alice Sebold's book. The film's currently slated for March 2009 release.
