With Batman vs. Superman adding more and more characters (in case you haven't heard, Ray Fisher as Cyborg is the latest addition), it's obvious Warner Bros. is taking big steps to establish a whole new DC cinematic universe. Today the studio has confirmed that yes, they're going to create a Justice League movie! Speaking with the Wall Street Journal, WB's president of worldwide production Greg Silverman confirmed that Batman vs. Superman will lead into Justice League. As expected, Zack Snyder (Man of Steel, Watchmen) will direct.
No release date has been set and a script is currently in development. The website states it's "unlikely" the movie will come out before 2018. Additionally, they say WB has other DC/Vertigo movies in development that are not connected to Justice League. Shazam, Metal Men, 100 Bullets, and Fables were listed.
As for a potential Wonder Woman movie, there's currently no plans, but WB's executives are "warm" to the idea. Sue Kroll, president of worldwide marketing, added, "with the right script, that could be viable. The world is ready for her."
