The studio and DC Entertainment has been considering several options for its superhero films, including a "Man of Steel" sequel for 2015, a Flash movie in 2016 and the Justice League film for 2017.
Zach Snyder, who helmed "Man of Steel," is co-writing the story with David S. Goyer, who will then pen the screenplay. Production is expected to begin in 2014, with an anticipated release date in summer 2015.
Studio made the announcment of the the Superman and Batman matchup to 6,000 people inside Hall H inside the San Diego Convention Center, where it also promoted "300: Rise of an Empire," "Godzilla," and "Seventh Son."
Warner Bros. has indicated that it planned to bring back Superman for a 2015 film if "Man of Steel" performed up to expectations. The film's worldwide box office has hit $622 million since its June 14 launch. "The Dark Knight Rises," starring Christian Bale, topped $1 billion in global box office last year.
The Batman-Superman movie could match the box office prowess of "Marvel's The Avengers." That 2012 Disney release, featuring Iron Man, Captain America, the Hulk and Thor, amassed $1.5 billion worldwide.
It would also move the Burbank studio closer to its long-planned all-star superhero pic "Justice League" -- finally fully exploiting its DC Comics library beyond Batman and Superman.
"Justice League" would bring to the screen such characters as Aquaman, the Flash, Wonder Woman and another Green Lantern, whose costly 2011 predecessor flopped.
