Director Zack Spyder?s decision to cast Ben Affleck as the Caped Crusader in Batman V Superman: Dawn of Justice was certainly one of the most controversial superhero movie casting decisions made in recent memory. However, Affleck?s performance as a middle-aged Bruce Wayne wound up being one of the more universally-praised elements of Snyder?s film, inspiring many fans to call for a Ben Affleck-starring Batman solo movie to be fast-tracked. Affleck won?t only be playing a more active creative role in the future of the DC Extended Universe when it comes to the Batman solo film, either. It?s now being reported that Affleck will be lending Snyder and screenwriter Chris Terrio a helping hand behind the camera on the in-production Justice League Part One, by serving in an executive producer capacity.
