Woody Harrelson defended his clash with a photographer at a New York airport Wednesday night as a case of mistaken identity -- he says he mistook the cameraman for a zombie. "I wrapped a movie called Zombieland, in which I was constantly under assault by zombies, then flew to New York, still very much in character," Harrelson said. "With my daughter at the airport I was startled by a paparazzo, who I quite understandably mistook for a zombie."
