Once again another egotistic director. The joker does not exist without Batman. Let me repeat that, the joker does not exist without Batman. Do u got it Todd? Now secondly, why lady Gaga? Come on weโre really gonna sit here and pretend like sheโs got real acting chops. No, no, thirdly, a musical? Really Todd?
