At San Diego Comic-Con it was announced that Batman: The Killing Joke would be one of the next animated movies from DC Comics and Warner Bros.. Tonight at the Batman: Bad Blood panel at New York Comic-Con we got word from producer James Tucker that Warner Bros. gave them permission to make it rated R!
