Following the box office disappointment of “Justice League,” Warner Bros. has been reevaluating its approach to making movies based on DC Comics characters. The studio is not moving forward with Batman and Superman movies featuring Ben Affleck and Henry Cavill, respectively. It is expected to recast the Dark Knight with a different actor.
