How ‘Lanterns’ Is Secretly Setting up Superman’s DCU Future

James Gunn’s rebooted DC Universe has spent the past two years building outward in careful, deliberate pieces, letting projects like ‘Creature Commandos,’ ‘Superman,’ and ‘Peacemaker’ establish a shared world before asking audiences to track how it all fits together. That patient approach has made every new crossover moment feel earned rather than forced, and it’s exactly the kind of connective tissue fans have started hunting for in every new release.

‘Lanterns’ arrived on HBO Max on August 16 as the next entry in that expanding universe, part of what Gunn and DC Studios have labeled Chapter One: ‘Gods and Monsters.’ On the surface, it looks like a grounded, moody crime drama, following veteran Green Lantern Hal Jordan and his reluctant trainee John Stewart as they investigate a mysterious death in small-town Nebraska.

But ‘Lanterns‘ is far more tangled up in the DCU’s bigger picture than its subdued tone initially suggests. The series jumps between multiple timelines, including 1986, 1996, 2016, and 2026, and one of those threads lines up directly with the opening moments of 2025’s ‘Superman’ film, tying the show’s mythology straight into Gunn’s cinematic timeline.

The clearest connective thread running through ‘Lanterns’ is Nathan Fillion’s Guy Gardner, who first appeared as an established member of the Justice Gang in ‘Superman’ before showing up again in ‘Peacemaker’ season two. His presence in ‘Lanterns’ places him alongside Hal and John during their 2016 investigation, reinforcing that all three Green Lanterns exist within the same continuity rather than separate, disconnected corners of DC’s catalog.

That timeline placement matters, since Hal has reportedly held his ring for decades before Superman ever became a public figure, meaning the Green Lantern Corps was quietly operating on Earth long before the world knew Kal-El existed. According to the show’s mythology, Superman’s arrival is even referenced on screen, with young John watching Hal discuss his own history during a televised interview around the same period Clark Kent’s ship reportedly touched down.

Beyond Gardner, ‘Lanterns’ also introduces Sinestro, played by Ulrich Thomsen, marking his first appearance anywhere in Gunn’s DCU. Since the character carries no prior on-screen history in this continuity, the show is free to build his introduction entirely on its own terms rather than leaning on outside context.

The connections don’t stop at ‘Superman.’ Both Aaron Pierre and Fillion are expected to carry their ‘Lanterns’ roles forward into ‘Man of Tomorrow,’ the previously announced ‘Superman’ sequel dated for the summer of 2027, while Fillion’s Guy Gardner is also expected to turn up in an upcoming ‘Mister Miracle’ series.

That forward momentum stands in contrast to how showrunner Chris Mundy originally described the project. Early in development, Mundy suggested the series wasn’t tied to a larger storytelling plan and was designed to work as a self-contained season of television first and foremost. Watching the finished product suggests that stance has shifted considerably as the DCU has taken clearer shape around it.

For a franchise still working to prove it can build a cohesive universe without losing what makes each individual story compelling, ‘Lanterns’ threading itself this tightly into ‘Superman’ and beyond feels like a meaningful signal. It suggests Gunn’s slower, more patient model of universe-building is starting to pay off exactly as intended.
