In a Variety article detailing the studio's forthcoming plans for its DC properties, a 2015 date is mentioned as a target to get the comic book team - featuring Superman, Batman and Wonder Woman - together on the big screen for the first time.
Following the box office success of The Avengers earlier this year, Warner Bros announced that Gangster Squad screenwriter Will Beall had penned a script for a Justice League blockbuster.
Warner Bros film group president Jeff Robinov revealed that plans for its superhero movie slate will be announced after the release of The Dark Knight Rises.
"My hope is that over the next month or so we'll be ready to lay out the plan for the next DC movies," he told the Los Angeles Times.
"It was a conversation we had," Robinov said. "Obviously anything you can get Chris involved in is great."
A Justice League feature was previously in the works with Mad Max director George Miller at the helm. The cancelled project would have starred Armie Hammer as Batman, DJ Catrona as Superman and Megan Gale as Wonder Woman.
Following the release of Dark Knight Rises on July 20, the next DC Comics adaptation to hit the big screen will be the Henry Cavill-led Superman revamp Man of Steel.
