WMG / Zack Snyder's Justice League

Acknowledgement or appearance of Supergirl

Instead of Superman, Steppenwolf's phrase "no Lanterns, no Kryptonian" might refer to Kara Zor-El's presence during Darkseid's invasion, as she crashed on Earth a few thousands of years before modern day in her tie-in comics. The full extent of deleted roles from the 2017 film might not have been revealed yet.

• Tossed. He's talking about Superman.

This film will make the theatrical cut Canon Discontinuity

Considering how this version is there to Win Back the Crowd, it’s pretty likely that it will replace that film in the timeline.

• When the "Flashpoint" movie happens, maybe this will provide an in-universe explanation for it.
• The Flash turns the theatrical version into an Alternate Timeline he creates when time-traveling to prevent the Knightmare future from happening.
• Tossed. There's no mention of the Flash creating an elseworld by going back through time.

The question of which version is canon will be revealed in an after-credits scene starring Mr. Mxyzptlk or Bat-Mite.

Ideally voiced by Gilbert Gottfried and/or Paul Reubens.

• It could be animated. If the animation is cheap enough, the sarcastic Mr. Mxyzptlk will make a dig at such as, “Look at me! I’m a page right outta history here!”
• Tossed.

The events of this movie exists because of the Crisis.

Set in the post-crisis multiverse, like how Earth-96's Superman went from black emblem, back to yellow, or how Earth-Prime shares slightly altered versions of the histories of Earths 1, 38 and Black Lightning's.

It'll be as if the original cut never happened.

• Tossed. The movie ends with several cliffhangers that were not followed through in the subsequent movies, this leads to the conclusion that the timeline that was erased was the on from the directors cut.

Steppenwolf will play the role of The Starscream.

He wants to rule Apokolips himself. And he propably have quite ambitious plans to utilize element of suprise and use the Mother Boxes against his nephew once he's done with Earth.

• Would be interesting to see. Has it ever happened in the comics? I know not everything has to be from the comics but I was wondering that when I read this so searched up "Has Steppenwolf ever turned on Darkseid?" and Google was woefully unhelpful.

• Tossed. Although the dialogue between DeSaad and Steppenwolf implies that this was the reason he was banned from Apokolips, he is completely in league with Darkseid and his conquering of Earth is seen as an act of redemption for his past betrayal.

Superman will be revived on his own.

Either he will just regenerate without any help at all, like it was suggested in BvS, or he will somehow absorb the power from The Mother Boxes once they will be used by Steppenwolf to complete the process.

• While it would be cool, and allow for Clark's return to be more of a Wham Shot, the Valentine's Day trailer appeared to show Johnathan Kent's photo falling into the Kryptonian Birthing pool thingy that was used to create Doomsday in BvS and revive Clark in the theatrical cut, suggesting that Clark will still be resurrected by the League... or someone else.
• Tossed. It's exactly the same as in the theatrical cut.

Lois Lane will survive this movie.

Her death (killed by Darkseid, or whatever) isn't this part of this movie arc at all.

• We do know that Snyder had to scrap that part of the story before principal photography began. The big question mark is whether or not he could film it as part of the planned pickups, considering the budget is higher than just what would be needed for a few new CGI. That also would run into whether or not the film will be retooled into a Grand Finale or if Snyder is confident enough to let plenty of Sequel Hooks in.
• Lois's death (sparking into the Knightmare future) would've actually happened in Justice League Part Two, not One (what this cut of the film will essentially be, especially if the story continues). This JL movie is meant to have an happy ending. For now at least.
• Confirmed.

Martian Manhunter will join the League.

In all likelihood he's going to be Serkis Folk like Cyborg and the New Gods. Plus, his big reveal has him switching between the forms of Martha Kent, his "green Superman" form and his General Swanwick form, so it wouldn't be too difficult to slip him into more scenes.

• Confirmed in the final scene.

Barry will see Barry.

While running through the Speed Force, Ezra Miller's Barry Allen will see flashes of other DC continuities, including a reprisal of his encounter with Grant Gustin from the CW's Crisis crossover.

• Tossed.

Predictions for previous music cues in the movie.

Zack Snyder and Junkie XL confirmed that Hans Zimmer's Man of Steel theme will return in this film. This could open the door for other tracks to appear, so here are some guesses:

• "Sent Here for a Reason" if there is a scene where Superman rummages through his past memories. Which could lead to...
• "What Are You Going to Do When You Are Not Saving the World?" during the Clark, Martha, and Lois hugging moment. More specifically, only the slow piano notes.
• "Flight" when Superman dons the black suit since one shot in the trailer has him emerge from the Kryptonian ship in the same pose as Man of Steel.
  • It's actually a reprise of "What Are You Going to Do When You Are Not Saving the World?"
  • The latter half of "Flight" is reprised in "Superman Rising Pt. 2 / Immovable".
    • Mostly confirmed. Additional returning themes include "Look to the Stars" which is reprised in "I Teach You, the Overman", "Arcade" and "You Die or I Do" are reprised in "Monument Destroyer".

Batman and Joker are working together

Knightmare is a full-time Godzilla Threshold situation. And a current fate of both Earth and mankind is so terrible, that even Joker is horrified. They are all fighting for survival and/or to avoid eternal enslavement, and any previous conflict is meaningless is comparison.

• Confirmed, though neither Batman nor Joker is particularly pleased with this.

Joker and Batman's Enemy Mine situation has something to do with Harley Quinn

Whether she convinced them to work together or if Joker is specifically there to avenge her death is unknown.

• Joker does admit that he misses Harley, implying as much.

Superman will gruesomely kill Joker in the Bad Future

As a Mythology Gag referring to the Injustice: Gods Among Us comics, of course.

• Tossed for this film, though who knows what happens afterwards...

Knightmare isn't the future, it's a parallel Earth

We know thanks to not only the narration but The Flash that other dimensions and alternate realities exist. Bruce's dreams/visions of the "future" happen when he synchronizes with his alternate self.

The promised mindblowing cameo will be Access

He will get involved in the final battle, and in an after-credits sequence, he will leave the universe, soaring through the vast blue extradimensional void filled with huge orbs representing universes (which have an odd habit of clustering in groups of 52) to once more guard the boundary between it and a vast red extradimensional void...

• Tossed. It's Martian Manhunter.

The young girl who asks Diana if she can be like her one day is Donna Troy

Diana addresses her as "Princess", maybe it's just a coincidence. If not Donna then one of the other people to take up the mantle.

Cyborg will be targeted by Apokolips

With his tech ability making him a match for the Mother Boxes, which Darkseid and DeSaad are after, he is bound to be captured and used by them for their own purposes, like what happened to him in Apokolips War.

Batman's superpower is clairvoyance

His "Knightmares" are not mere perceptions entirely generated by his brain (i.e. dreams): they are actually visions of the future. This explains how he could dream about Barry Allen "being too early" in BvS, when he didn't even know about Barry Allen's existence, let alone the powers he had.

• As a corollary, he regularly used clairvoyance to be always sure to make the right investments and become so rich.
  • This could also lead to an epic and extremely dark scene, set even later during the Knightmare future, where Batman has to fight an evil Superman, who manages to burn Batman's eyes and the surrounding skin on his face via Eye Beams. As a result, Batman's appearance turns into a twisted version of his comic book look: milky white blind eyes, surrounded by charred black skin. Then Superman tries to hit him, believing this to be a Curb-Stomp Battle due to Batman's blindness... and Batman dodges. Again and again. This is followed by an Armor-Piercing Question by Batman: "Tell me... when does the future start?" Cue Oh, Crap! look by Superman, who realizes Superman could not use his eyes anymore, but he could still use his clairvoyance to see a millisecond into the future, nullifying his blindness.

How the Knightmare future came about and how it can be prevented

Working off a bit from a theory in this video and What Could Have Been, where Snyder had originally envisioned a relationship between Bruce and Lois that developed during Clark's death, which in turn led to Bruce hesitating at a crucial moment to protect her from being killed by Darkseid because he wasn't sure if the child she was pregnant with was his or Clark's. Naturally, it got Executive Vetoed, but there was still that line from Knightmare-Superman back in BvS ("She was my world... and you took her from me.") that still apparently alludes to that original plan. So basically, it wasn't just the loss of his wife and unborn child that rendered Superman vulnerable to Anti-Life, but it was also being shown by Darkseid that the two people he thought he could trust went behind his back like that and that the kid might not even have been his. However, Barry going back in time to warn Bruce but going back too early ends up inadvertently being what's needed to prevent the Knightmare - Bruce knows beforehand that Lois is "the key" to Superman so he doesn't try anything shady with her and thus feels more driven to actually do what he needs to do to prevent the Knightmare from happening.

For all intents and purposes, the scene between Lois and Martha did happen for both of them.

J'onn J'onnz was as invested in helping Martha come to terms with her grief for Clark as he was for Lois. So, as soon as he had concluded the meeting with Lois for which he had impersonated Martha, he went to the real Martha and used Martian mind-altering telepathy to (very carefully and sensitively) impart the memory of the conversation upon her. Along with aiding their recovery from grief, it also ensured that no awkward follow-up would occur should Lois ask Martha about the conversation which in reality, she never really had.

Apokolips is sandy

In the Knightmare sequences, we see the Earth is now all sandy. And in Zack Snyder's original plans, Darkseid was supposed to get his hands on the mother boxes and use them against Earth. And since the Mother Boxes turn planets into copies of their users' home world. We can infer that the Apokolips in this universe happens to have a lot of sand
