Mirror, mirror, on the wall, where are the most loyal Woody Allen fans of all? Apparently not in New York, despite the film maker's legendary love affair with the Big Apple. According to Orion Pictures, the last theater in the United States still playing Allen's "September" is in San Francisco--where the drama took in about $4,000 at the Vogue last weekend. For the most part, audiences and critics turned thumbs down on "September," which has grossed only $440,000 since its limited release on 15 screens in December. On Manhattan's Upper East Side, meanwhile, Loew's New York Twin replaced the Allen film last weekend with Cannon's "Braddock: Missing in Action III," starring Chuck Norris.
