Justice League takes place about one year after the events of Suicide Squad and deals with the fallout of the death of Superman. The film features Steppenwolf and his parademons as the main villains and stars the returning cast of Batman v Superman. The theatrical cut of Justice League was finished by Joss Whedon after Zack Snyder left during post-production and after hefty reshoots that largely abandon teases for future DC films. Zack Snyders Justice League, on the other hand, is Snyders epic four-hour version of the story that teases grand DCEU plans that will not be coming to fruition following his departure.
