Justice League 2 hasn't been confirmed and doesn't seem likely to happen any time soon, even with one key player in particular returning to his role as Superman... but more on that in a minute.
Charles Roven, DC's longtime producer, shared his hopes that he'd be involved in another Justice League movie back in August 2021. However, he noted that any potential sequel would be a "number of years away".
Zack Snyder was even less sure about a follow-up to Justice League, even after his version of the film was released on HBO Max in March 2021. He also claimed that Warner Bros has been "aggressively anti-Snyder", meaning it seems unlikely that a sequel would be greenlit.
Snyder's cut of Justice League ended on a "massive cliffhanger", as he promised fans it would, which obviously leads to more Justice League films as per the original studio plan. All of that, however, feels like dust in the wind at this point.

Of course, that doesn't mean fans aren't hankering for more from Snyder. And with the new direction that James Gunn plans to take the Worlds of DC (plus The Flash set to bring the multiverse) there may yet be hope.
If that happens though, what can we expect to see from Justice League 2? Here's what we know so far about the chances of a sequel and plot details.
Justice League 2: Will Zack Snyder's Justice League get a sequel?
Right now, it looks as though the new version of Justice League will satisfy Snyder fans, but is about as far as his vision of the team will go.
In January 2021, Snyder told ComicBook Debate that he has "no plan" to continue this world despite his original plan for more movies as he's "got a lot going on". He did add though: "But like I said, I didn't think I'd be here, so who knows?"
For Warner Bros, Zack Snyder's Justice League has reportedly been described as a "storytelling cul-de-sac" and not something that will be continued, which is how Snyder sees it right now too.
In an interview with The New York Times ahead of the movie's release, Snyder referred to it as "the last movie I make for the DCU", adding that even though it ends on a cliffhanger, it's not because he's planning more movies.
However, until May 2020, nobody really thought we'd be seeing Snyder's definitive take on Justice League, so you can never rule anything out. As mentioned above, the plans to introduce the multiverse could see Snyder's version of this world continuing without affecting other ones.
That would be a fair few years away though by all accounts (and still unlikely), so we imagine that if Snyder does return to DC, it might be for a different movie rather than a direct sequel to Justice League.
Justice League 2: What was Zack Snyder's original plan?
We're about to go into some major spoilers for the end of Zack Snyder's Justice League, so look away now if you haven't seen it yet.
As in the original version of Justice League, the big climax is our heroes taking on Steppenwolf to stop him uniting the three Mother Boxes.
After a minor blip where The Flash has to reset time a bit, they succeed and kill Steppenwolf with Wonder Woman beheading him as he's pushed back through the portal to Apokolips.
However, the major difference is that Darkseid – DC's answer to Thanos – plays more of a role in this version of the movie, and he vows to come to Earth to defeats the heroes and get his hands on the Anti-Life Equation.
We then see more of Knightmare (the dark apocalyptic future first seen in Batman v Superman), and when Bruce Wayne wakes up from the vision, he has a chat with the Martian Manhunter who pledges to help in the coming war.
Originally, this was going to be Green Lantern rather than the Martian Manhunter, but Snyder wasn't able to use the already-shot scene with Wayne T Carr as John Stewart. Perhaps he'll pop up in a potential sequel though.
Snyder's original Justice League plan would have been very similar to the Avengers: Infinity War and Endgame arc where our heroes were defeated, only to be brought back for one epic final battle with the help of time travel.
But don't take our word for it, here's how Snyder described the plan for the sequels to The New York Times. "It's the fall of Earth, when Superman succumbs to Anti-Life. And then sending Flash back in time to change one element so that doesn't happen. And then the big battle where we beat him," he said. "When Darkseid comes to Earth, in the movie that you'll never see, the armies of Earth all unite again, as they did before.
"This time there would be aircraft carriers and Special Forces guys, all the armies of the world would come together, as well as Atlanteans rising out of the ocean and the Themyscirans coming off their island. That was our big finale. But it's a long drum roll and guitar solo to get there."
It's an ambitious plan that we're sure Snyder fans would want to see happen one day, but as we mentioned before, it seems like fans will just have to make do with Snyder's description of the sequels for now.
Justice League 2: Reboot time?
The likeliest option right now for a Justice League 2 – or another Justice League movie, rather than a direct sequel – seems to be a reboot, similar to James Gunn's approach to The Suicide Squad.
That being said, while Ben Affleck is no longer Batman (although he will appear in The Flash) and Cavill has actually returned as Superman meaning a soft reboot, or a simple recasting of Batman, may make a direct sequel less unlikely.
Justice League 2 could conceivably go ahead without them, we suppose, although they are traditionally core members of the team. Otherwise, DC would be looking at recasting some of its leads while retaining Gadot, Momoa and the rest, a confusing proposition to be sure.
Either way, a new Justice League sequel looks a long way off.
At least with their recent box-office successes, Warner Bros has finally shed its reputation as a studio unable to make superhero movies work – so that means we can never rule out another attempt at a team-up movie.
Zack Snyder's Justice League is available to watch now on Sky Cinema and NOW in the UK and on HBO Max in the US.
