"I'm not saying I'm going to do that. What was interesting to me about the inclusion of Batman in our movie was, 'What kind of Batman does that Gotham make?' That's all I meant by that," Phillips added.Warner Bros, the studio behind Joker, is already working on a film about the superhero. Titled "The Batman", the film is being directed by Matt Reeves and features Robert Pattinson as the titular hero.
