Zack Snyder's director's cut of Justice League (2017).
Following the death of Superman in Batman v Superman: Dawn of Justice (2016), Batman and Wonder Woman recruit the Flash, Aquaman, and Cyborg to form the Justice League and protect the world from Steppenwolf and his army of Parademons, who seek the three Mother Boxes.
Originally planned to be released as a four-part miniseries, it will instead be released as a four-hour movie.
