It would admittedly feel somewhat odd for Ben Affleck to immediately delve back into Dark Knight Returns/Knightfall territory in the very first Batman movie to hit theaters after Nolan's last outing. That being said, we expect that Affleck will likely blend Knightfall with other Batman stories to create something entirely new. Perhaps the film will feature the Court of Owls, or maybe it will also adapt elements from Geoff Johns' Batman: Earth One. We're just going to have to wait and see what happens over the course of the next year. All we know for certain is that another Knightfall adaptation seems incredibly likely.
