Mayor of Batman sues WB, Nolan Southeastern city in Turkey fights for name Batman has a new adversary: Batman. The mayor of an oil-producing city in southeastern Turkey, which has the same name as the Caped Crusader, is suing helmer Christopher Nolan and Warner Bros. for royalties from mega-grosser "The Dark Knight." Huseyin Kalkan, the pro-Kurdish Democratic Society Party mayor of Batman, has accused "The Dark Knight" producers of using the city's name without permission. "There is only one Batman in the world," Kalkan said. "The American producers used the name of our city without informing us."
