DCU Justice League Rumors Get Huge Boost After Hidden Detail Spotted On Superman Set (2024)

With Superman still in production, new photos of an upcoming DCU set may be hinting at a Justice League setup within the DC Universe installment. James Gunn's DC Universe is closer to becoming a reality, as the Creature Commandos TV show will premiere in December, followed by the new Superman movie in 2025 as part of DCU's Chapter 1, "Gods and Monsters." While David Corenswet will star as the new Man of Steel in the DC Universe, many other heroes are also getting reimagined for the big and small screens.

As Superman set photos have been shared online over the last week, various DC Easter eggs have been spotted throughout the production. A recent one is now sparking some major Justice League theories, as the Greater Cleveland Partnership shared images from the upcoming movie filming location, with banners marketing Metropolis, while including a blueprint of the Cincinnati Union Terminal. DC fans may recognize that as the inspiration for the Hall of Justice, and the account mentions Superman is set to move production to Cincinnati, fueling the idea that perhaps the Justice League's famous headquarters is making its way into the film.

Will The Justice League Be Created In Superman?

DC Studios has made it clear that Gunn's DC Universe will have a lot of established superheroes already - including Superman, as Corenswet's iteration will already be operating as Metropolis' guardian angel. However, with a Justice League movie not happening any time soon, this begs the question of how long it will be until the team is properly born in the DC Universe. One possibility that could happen in the Superman film is Gunn planting the seed for the Justice League to eventually come to fruition.

Given how the Superman movie cast will include several Justice League members, it is unclear what the status of the Justice League is at this point in Gunn's continuity. If the Superman production is indeed going to use the Cincinnati Union Terminal - at least for their exterior shots - in the film, it wouldn't be shocking if the idea of a Justice League team is born towards the end of the film. Depending on where the story is going, it would make sense if Superman comes to the realization that a new hero team is needed, and thus begin the process of setting the Hall of Justice up.

Some of the recent Superman set photos with Hawkgirl, Green Lantern, and Mister Terrific have also suggested that Justice League International may be something that they will lay the foundation for in the movie, who could also use this as a prospective base. It would also be genuinely amazing to see the Hall of Justice finally be featured in a live-action film, and having Superman be the first film where it is featured is only fitting. As Superman gets into the final weeks of filming, time will tell what else fans may get a sneak peek of through set photos before July is over.
