On March 25, Batman v Superman: Dawn of Justice hit theaters and marked the start of the DC Comics cinematic universe expansion. The film introduced Batman, Aquaman, Cyborg, Wonder Woman, all alongside Superman. Ultimately, the plan was to have these characters meet up for an ensemble movie in Justice League, which was announced all the way back in October 2014. However, not just any ensemble movie. Two ensemble movies. Warner Bros listed the upcoming films Justice League Part One and Part Two, and scheduled them for release in 2017 and 2019. Now, however, according to Entertainment Weekly, the Justice League movies have been scaled back by 50 percent. The film Zack Snyder's working on right now will apparently be part one of only one Justice League film. So it's looking like Justice League won't get a sequel.
What's more, according to what Deborah Snyder (wife of director, Zack and producer of Justice League) told Vulture, there wasn't ever going to be two movies. “We were only ever planning and we are only doing Justice League,” Deborah Snyder told Vulture. “Just Justice League. One movie.” According to Vulture, when reporters asked if the one movie would be split into two parts, Deborah said, “No.”
So Justice League will be one film and one story. What does that mean for the already scheduled 2019 movie? Will they just scrap it entirely? Perhaps it will be a different story, have a different title, but still feature the same cast of characters (kind of like what Marvel did with The Avengers and then Age of Ultron), but at this point its too early to tell. Plus the folks behind the films aren't giving us a whole lot of clarity. When asked about the Justice League sequel, Zack also told Vulture, “I think we still have a release date... As far as I know." What? But Deborah just said, and you just said, and... what?
Warner Bros did set release dates for 10 films up until 2020. Wonder Woman will come out next summer, Aquaman's set for 2018, and Cyborg and Green Lantern films are still premiering in 2020, just to name a few. According to Zack's cryptic "As far as I know" comment though, maybe this slate is more malleable than it seems.
