James Gunn isn’t slowing down when it comes to reshaping the DC Universe. Today, Gunn officially announced that the next chapter in the Superman saga, Man of Tomorrow, will soar into theaters on July 9, 2027. And if that wasn’t big enough news, the internet is already ablaze with rumors that the film may not be a solo outing.
A New Dawn for the Last Son of Krypton
Following Superman (2025), which is set to reboot Clark Kent for the new DCU, Man of Tomorrow promises to expand on the mythos while keeping Gunn’s signature mix of heart, humor, and cosmic scale. Fans have long speculated about how the DCU will handle Superman’s rogues’ gallery, and the title itself hints at themes of legacy, hope, and possibly the introduction of a world not yet ready for the Man of Steel’s vision of the future.
The Team-Up Rumor That Has Fans Buzzing
But here’s where things get interesting: multiple insider reports suggest Man of Tomorrow might secretly be a team-up film. The whispers range from a partnership with the fan-favorite Batman (potentially the DCU’s “The Brave and the Bold” version) to a more unexpected ally—like Green Lantern or even Lex Luthor in a temporary alliance against a bigger cosmic threat.
One rumor making the rounds? Brainiac could serve as the central villain, forcing Superman to join forces with someone he’d normally battle against. The recent concept art leaks of Luthor’s high-tech warsuit (think glowing green Kryptonite core and Iron Man–meets–Kaiju armor) have only added fuel to the speculation.

Why This Matters for the DCU
A Superman team-up movie this early in Gunn’s DCU would be a bold move, signaling that the studio is wasting no time weaving its heroes into interconnected stories. Marvel waited years before Avengers. Gunn, however, seems intent on giving audiences larger-than-life crossovers much sooner.
The release date—smack in the middle of summer blockbuster season—shows Warner Bros. Discovery is betting big on Man of Tomorrow to not just continue Superman’s story, but also solidify the DCU as a true competitor to Marvel’s cinematic dominance.
Fans React
Predictably, Twitter (or X, if you insist) has already exploded. Some are hyped at the idea of Superman and Batman sharing the screen again, while others are desperate for a first live-action Green Lantern team-up since 2011. And of course, a chunk of fans are praying the rumors point to a Brainiac showdown, something teased in comics and animated films but never realized on the big screen.
The Bottom Line
While James Gunn and DC Studios are keeping the official details tightly under wraps, one thing is clear: Man of Tomorrow is shaping up to be more than just another Superman movie. Whether it’s a team-up, a face-off with Brainiac, or a game-changing twist we haven’t seen coming, the 2027 release could be the defining moment for the DCU’s next era.
Until then, fans will just have to keep speculating—and refreshing Gunn’s Twitter feed—for the next breadcrumb.
