Documentarian Michael Moore is nosing around Philly, and pharmaceutical giant GlaxoSmithKline could be in for a Paxil moment. Moore, who skewered the Bush administration in Fahrenheit 911, has his production staff doing groundwork for his next project, tentatively titled Sicko, an indictment of the U.S. health-care system. Moore is trying to get workers at the company's Center City headquarters to talk on camera, according to one who was approached. GSK has ordered silence, per long-standing policy. A GSK official said she was unaware of any contact.
