Previous reports have pointed to the possibility of Affleck’s departure, despite public comments about his being committed to the project.
Losing Affleck entirely would be a major blow to the cinematic universe Warner Bros. is building, leaving the studio in a difficult situation of having to recast arguably its biggest and most recognizable character.
Warner Bros. and DC Entertainment president Geoff Johns have been quiet throughout this entire process, which only fuels speculation about what, if anything, is actually happening behind the scenes of the film.
Given the magnitude of what is at stake and the potential shakeup that a departure by Affleck would cause the DCEU, it is best to take this news as pure speculation until it is proven otherwise.
