As a sequel? I don’t think so and I hope not in the chances that it ruins the things that made it great in the first place. But there could be chances of developing spin off films or series of that world if they don’t decide to blend it with Pattinson’s Batman universe

What I feel like they should do now after joker is to try and recreate this success with other iconic villains like reverse flash, Luthor, or other batman villains like riddler or Ra's Al ghul

I talked with the director and he said that he doesn't have any plans for a sequel but there might be one in the future.
