With Batman v Superman: Dawn of Justice about to hit cinemas, director Zack Snyder is preparing to start work on his next DC movie. It has been confirmed that Justice League Part One will begin production in April.

As reported by EW, the film will start shooting on April 11, for a November 2017 release. Snyder spoke about the challenges of making a movie featuring a large number of DC superheroes, some of whom will have had relatively little screentime in the films leading up to it.

“It was a little bit of an ‘about time’ moment, and I don’t blame [the studio] for feeling that way, because it’s a long time coming,” he said. “But I do feel like it’s a little bit of a creative hurdle. It seems like an easy thing to do at first glance, the idea that, ‘Oh, we just get the rest of the superheroes in there.’ But you have to [establish] a world where they can exist.”

Justice League Part One will be the fifth movie in DC’s cinematic universe, with Suicide Squad and Wonder Woman preceding it. Subsequent movies in the universe will include The Flash, Aquaman, and Shazam.

It has also been confirmed that Dawn of Justice will have a running time of 151 minutes. The film’s length was confirmed by the AMC Theaters website, making it three minutes longer than Snyder’s previous DC movie, 2013’s Man of Steel.

Batman v Superman: Dawn of Justice opens on March 24, 2016. Justice League Part One arrives on November 17, 2017, while Part Two follows in 2019.
