The LA Times reports that Warner Bros. is aiming to release a live-action movie based on DC Comics' Justice League team in 2015. The team would consist of Superman, Wonder Woman, Batman and other characters. A script is already in the works and the studio now needs to find someone to direct as well as find a cast to fill the iconic roles.
Warner Bros. plans to spin-out movies based on Justice League team members after the release of the Justice League movie. Essentially taking a reverse course competitor Marvel and Disney took with the Avengers. It is not likely that Christopher Nolan's Batman movies will have any connection with this movie nor is it clear if next years "Man of Steel" Superman movie will have any barring on Justice League.
