What fans have known for a very long time has finally been officially confirmed today: a standalone Batman film is coming, with Ben Affleck presumably not just behind the cowl, but at the helm.
Today at CinemaCon in Las Vegas, CEO Kevin Tsujihara spoke about Affleck's involvement with the future of the DCEU: "We're working with Ben Affleck on a standalone Batman movie," he stated. Given the context of the conversation, many at the panel took that to mean Affleck will indeed be directing the standalone film, a belief that was bolstered by Affleck himself making a surprise appearance at the panel.
Along with the standalone Batman film, Tsujihara said that Warner Bros. is planning "at least 10" films set in the DC Extended Universe over the next five years. It makes sense that they are bringing Affleck on board as much for his behind the camera abilities as what he brings in front of it to help shape the Batman branch of the DCEU, a common sense theory that was the topic of much speculation when Affleck first signed. Zack Snyder, after all, can't be expected to build the entirety of the universe on his own - much like Marvel has done with a different director taking the reins for each separate phase, WB can't rely entirely on Snyder.
Whether or not fans agrees with how Batman was portrayed, Affleck's acting as Batman was one of the best-received parts of [Batman v Superman: Dawn of Justice](tag:711870). After the divisive mess that was the aftermath of BvS's release, it's smart of WB to announce Affleck's involvement. Not only is Affleck now appearing to direct, he also revealed earlier that he and writer Geoff Johns are teaming up for the script. Hopefully, the team of Affleck and Johns will assuage fans' fears and help to win back some of their faith in the future of the DCEU.
No official release date has been set yet for the standalone Batman film.
