I cannot believe I missed this breaking zombie news:
Woody Harrelson's explanation for an alleged tussle with a TMZ photographer at New York City's La Guardia Airport Wednesday night is Method acting. "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 in a statement issued by his publicist and obtained by CNN. "With my daughter at the airport I was startled by a paparazzo, who I quite understandably mistook for a zombie." --Entertainment Weekly
Makes sense to me.
