Warner Bros/DC. is reported to have begun resurrecting plans for a Justice League movie before The Avengers hit theaters this past summer, but it was the overwhelming success of Joss Whedon's Marvel comic book movie blockbuster that cemented the studios' decision to move forward with their own superhero ensemble venture. Will Beall (writer of the much-buzzed-about Gangster Squad) is currently working on the script for the JL movie, while the search for a director is ongoing.
While it's seemingly a given that Justice League will reboot the Batman franchise (in the aftermath of Christopher Nolan's trilogy finale, The Dark Knight Rises), there has been some uncertainty about whether or not key new elements from the Superman mythos - featured in next summer's Man of Steel - will be sustained in Beall's script. Part of that can be attributed to Warner Bros.' ongoing battle with co-creator Joe Shuster's estates over the character rights (after their previous agreement runs out this year).
Following yesterday's announcement that Warner Bros./DC has won its battle against the Shuster estate, the studios no longer have to be concerned about not being able to carryover unique elements from Man of Steel in future movies, TV shows, or even comic books. Hence, Justice League (which may have ties to Zack Snyder's Superman reboot) is gearing up to begin production next year, in order to make a summer 2015 release date. That means the film will compete with Marvel's The Avengers 2 for the superhero movie box office crown - though, it goes without saying that the two will be hitting the big screen at different times of the season (to allow one another room to breath).
The LA Times expects development on Justice League to meet that target date, as progress should accelerate in the aftermath of the court victory for Superman rights. It appears the studios' plan is indeed to take the opposite route that Marvel took to shared universe construction. JL will therefore be the first in a new wave of DC movies to hit theaters after Man of Steel, with the subsequent films arriving in the forms of standalone vehicles for JL members such as Wonder Woman, The Flash, and possibly a rebooted Green Lantern arriving sometime thereafter (assuming JL proves to be a satisfactory success).
The ball is now in Warner Bros./DC's court, in terms of the risks and daring moves the studios are willing to take with Justice League (in addition to forgoing five movies of buildup, like what The Avengers had). We've offered our own advice on such matters as how to go about assembling the DC shared universe, how to properly reboot Batman post-Nolan, and even how incorporating an unusual DC anti-hero like Lobo could be an important maneuver to help set apart JL from Avengers. It's now up to Warner Bros./DC to find a candidate as qualified for the directing job as Joss Whedon proved to be for the task of bringing Earth's Mightiest Heroes together on the big screen (free advice: people like McG and Brett Ratner really don't seem to meet that criteria).
