The Batman - Part II is one of the few aspects of the old DC regime at Warner Bros. that has survived under James Gunn and Peter Safran's DC Studios. The upcoming sequel will now fall under the DC Elseworlds banner and remain separate from the interconnected DCU. Matt Reeves' first film was a major success for DC as it set new ground for the comic book movie genre. The Batman - Part II will begin filming sometime this year with a current release date set for October 2025. Many rumors have been floating around regarding who will serve as the sequel's main antagonist.
