Zack Snyder’s Justice League is now out there in the world for everyone to pick apart (read our review). And since the film is four hours long, there is plenty to dissect. However, like most comic book movies, it is the ending where a lot of the mystery has come into play. The finale scenes have a number of moments that seem to set up a much larger story. Whether or not we will ever see them play out is a whole other conversation, but it is worth delving into exactly what these scenes mean for the larger DC Extended Universe and what it could mean for future movies.
Obviously, this will feature SPOILERS for Zack Snyder’s Justice League.
There are a few scenes at the end of Zack Snyder’s Justice League that deserve some explanation. The first one involves a strange other world that looks to be post-apocalyptic. This is the Knightmare, a potential universe where Lois Lane is killed and it causes Superman to come under the sway of the evil alien Darkseid when he invades Earth. This leads to a decimated Earth where only a few heroes and villains are left alive and have banded together for survival. As the scene starts, we see that Batman, Mera, the Flash, Cyborg, Deathstroke, and the Joker are all working together in order to try and defeat an evil Superman. They share some dialogue talking about how various others have been killed such as Aquaman and Harley Quinn before Superman shows up and possibly kills them all.
It is important to say that there is an acknowledgment that the characters know there are other universes and timelines, and it looks like a sequel to Zack Snyder’s Justice League would explore the Knightmare timeline characters trying to prevent their future from ever happening. However, since an evil Superman pops up to fight them all, there is the question of who would even survive that encounter with the warped Man of Steel.
But, there is another scene at the end of Zack Snyder’s Justice League that bears explanation. This Knightmare vision is seen as a dream from Bruce Wayne’s perspective, which is also how it appeared in Batman v Superman: Dawn of Justice. This time, after waking from his nightmare, Bruce Wayne is met by a strange floating alien. This is the Martian Manhunter, one of the founding members of the Justice League in the comics. He tells Bruce that he has been keeping an eye on the heroes and that there are other threats that they need to face in the future. It looks like Martian Manhunter would have been an integral part of the team in any sequel.
Although these endings do set up the possibility of a continuing story, we do not yet know if Warner Bros./DC plans to pick up on any of the threads that were left here in this version. If not, then that really is all the explanation we can expect unless Zack Snyder decides to tell us exactly what his entire plan was for the sequels. Without that, this is all we have to go on.
