No, the Batman in the films isn't suing the big name director, the town of Batman is.
Hüseyin Kalkan, the pro-Kurdish Democratic Society Party mayor of the southeastern city of Batman in Istanbul, declared war against his city’s namesake superhero, Batman.
“The royalty of the name ‘Batman’ belongs to us … There is only one Batman in the world. The American producers used the name of our city without informing us,” Kalkan told to the Doğan news agency. Batman is a centuries old city, taking root in the Neolithic age but becoming significant when oil was found in the region at the end of 1940s. Almost a decade before that, Batman was created as a comic hero. Kalkan is going to sue Christopher Nolan, the director of the latest Batman movie, not DC Comics, the creator of the superhero.
Mayor Kalkan, speaking to the Hürriyet Daily News and the Economic Review, said last year foreign media picked up on Batman and the city’s increasing suicide rates among women. He said a columnist asked why Batman’s mayor did not sue the movie Batman for royalties while struggling with economic problems. 'We found this criticism right and started to look for legal possibilities of a case like that,' he said."
