Before stepping away from the role altogether, Ben Affleck was slated to direct and star in The Batman. Although he left the role earlier this year and Matt Reeves replaced him as director, Affleck is still willing to direct another DC film in the future.
When asked by LADBible if he'd want to direct a different DC Extended Universe film, Affleck said, "I imagine it would be weird to step in and do another character. I can certainly imagine directing a movie, you know - if they [DC] would have me - if it was something I was passionate about. It's not about like kind of closing doors on stuff, I just couldn't figure out how I wanted to do that one [next Batman film], so it became time to let someone else take a crack at it."
So it seems that despite the fact he wasn't able to create a Batman film, Affleck is still very much open to working with Warner Bros on its cinematic universe again should a captivating character and story arise. Whether such an opportunity will appear remains to be seen.
The two-time Academy Award winning actor and filmmaker debuted as the DCEU's Batman in Batman v Superman: Dawn of Justice in 2016. Affleck stepped away from the directorial chair on The Batman as he found himself unable to make a movie he thought was worth doing. It's currently unknown who will replace him, though it sounds like Reeves is eying a younger actor to play the Dark Knight.
The Batman is written and directed by Matt Reeves. It is scheduled to be released on June 25, 2021.
