James Gunn has quietly dropped a timeline bombshell about his DCU, confirming that Superman: Man of Tomorrow takes place roughly two years after 2025’s Superman in “basically real time” – and that single detail is already forcing fans to rethink how another key project, Peacemaker season 2, is supposed to feed into the sequel’s story, as first pulled together by ComicBook.com.
Gunn has said from the start that Superman is the formal launchpad of the new DCU, introducing David Corenswet’s Clark Kent, Rachel Brosnahan’s Lois Lane, and Nicholas Hoult’s Lex Luthor in a world where other heroes already exist. Between that film and the announced 2027 sequel Man of Tomorrow, DC Studios is threading in other Chapter 1: Gods and Monsters entries like Creature Commandos, Waller, and the second season of Peacemaker. Gunn’s recent clarification that the gap between the first and second Superman films mirrors the real-world two-year release window gives those projects a fixed spot on the board rather than a vague “somewhere in there.”
What we know of Man of Tomorrow so far paints it as a bigger, more cosmic escalation of the Metropolis status quo. The film is expected to force an uneasy alliance between Superman and Lex Luthor, with Hoult’s Lex donning his classic green-and-purple warsuit to confront a threat too big for either to handle alone. That threat is widely understood to be Brainiac, with German actor Lars Eidinger tapped to play the cold, hyper-intelligent Coluan villain. In the DCU’s first film, Lex had already developed a pocket-dimension prison for metahumans – a concept that now echoes uncomfortably with the other side of Gunn’s universe in Peacemaker.
Peacemaker season 2 ends with a very different kind of prison: Christopher Smith is arrested by A.R.G.U.S. and dumped into an inter-dimensional facility called Salvation. The show’s Salvation is heavily inspired by the comics limited series Salvation Run, where Earth’s government secretly exiles supervillains to a hostile alien world (also known as Cygnus 4019), and the rogues quickly split into warring factions—some trying to escape, others trying to build empires. In Gunn’s DCU, Salvation is framed as a prototype or parallel to Lex’s own pocket prison tech from Superman, suggesting A.R.G.U.S. is quietly building its own answer to uncontrollable metahumans and off-world threats.
That’s where the new timeline detail complicates fan theories. Before Gunn’s “real time” comment, one popular idea was that Peacemaker season 2’s cliffhanger was setting up Salvation as a direct, near‑term threat to Superman. Since Clark was previously trapped in Lex’s pocket dimension, some fans speculated that Rick Flag Sr. and A.R.G.U.S. might attempt to upgrade or repurpose Salvation as a place to lock away Kryptonians, with Peacemaker effectively serving as a test subject. But if Peacemaker season 2 unfolds shortly after Superman, and Man of Tomorrow is set a full two years later, that raises a pointed question: if Salvation is truly capable of holding beings on Superman’s level, why hasn’t A.R.G.U.S. tried to use it on him at any point in that two‑year gap?
The implication is that Salvation may be less of an immediate Superman trap and more of a slow‑burn DCU powder keg. One possibility is that A.R.G.U.S. simply never gets the chance—or the political cover—to weaponize Salvation against Earth’s frontline heroes before things spiral out of control on its own. Another is that Gunn is deliberately keeping the Superman films focused on threats like Brainiac and Lex’s evolution, while letting the consequences of a supervillain prison planet (or dimension) play out in the more morally murky corners of the universe: Peacemaker, Waller, and whatever black‑ops and espionage titles follow. It would fit Gunn’s pattern from his Marvel days, where teases like Adam Warlock’s cocoon simmered in the background for years before paying off.
What the “basically real time” confirmation does solidify is the state of the board when Man of Tomorrow opens. Lex has likely been incarcerated—or at least publicly sidelined—for around two years, having had plenty of time to stew over both his defeat and humanity’s dependence on Superman. The Justice Gang (the DCU’s emerging answer to a Justice League) has been operating long enough to grow more coordinated and visible, which could explain why a cosmic strategist like Brainiac decides this is the moment to make his move. And Superman himself is no longer the rookie hero from the first film; by 2027 in-universe, he’s a seasoned protector facing an enemy who studies worlds the way Lex studies power structures.
For fans tracking every thread of Gunn’s interconnected DCU, the timeline reveal is less about “breaking” the Peacemaker setup and more about reframing it. Salvation’s introduction now reads like the start of a larger metahuman-control storyline that may ripple across multiple projects instead of funneling directly into Man of Tomorrow. Meanwhile, the Superman sequel is positioned to tackle the franchise’s first truly existential, brain‑over‑brawn villain, with Lex’s warsuit and hard‑won knowledge of extradimensional prisons making him a necessary, if untrustworthy, ally. It is a slower, more modular approach to universe-building than the old DCEU, but for viewers willing to play the long game, Gunn’s “real time” DCU may make every cliffhanger—and every two‑year gap—matter a little more.
