‘Lanterns’ Ties Into Superman and James Gunn’s DCU in Ways Casual Viewers Might Have Missed
‘Lanterns’ has landed on HBO Max as one of the more grounded entries in James Gunn’s rebuilt DC Universe, trading widescreen spectacle for a slow-burn detective story. The series arrived on HBO Max on August 16 as part of what Gunn and DC Studios have labeled ‘Chapter One: Gods and Monsters,’ and on the surface it looks like a 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. Beneath that restrained tone, though, the show is doing quiet, deliberate work to link itself to Gunn’s larger cinematic plans.
That connective tissue matters because ‘Lanterns’ is not an isolated spinoff. The show takes place firmly within the DC Universe, with its central investigation unfolding in 2016 while other events happen in 2026, and it precedes the upcoming Superman sequel ‘Man of Tomorrow,’ where John Stewart appears once again. Understanding how the two projects overlap gives viewers a clearer sense of where Gunn’s DCU is actually headed.
Guy Gardner Bridges ‘Lanterns’ and ‘Superman’
The clearest link between the two projects is Nathan Fillion’s Guy Gardner. Lanterns is directly connected to James Gunn’s Superman movie, and this has been confirmed by the fact that Fillion is reprising his DCU role as Green Lantern member Guy Gardner in the series, after also appearing in Superman. That casting alone plants the show firmly inside the same continuity as the 2025 film rather than treating it as a separate corner of DC’s catalog.
Guy’s presence also reflects how the Green Lantern Corps functions within the source material. In DC Comics lore, two Green Lantern officers are typically assigned to a single sector of space, and Superman already establishes Guy as one active officer of that sector, with Lanterns focusing on his partner Hal Jordan as Hal nears the end of his service and trains his eventual replacement, John Stewart. That structural detail is part of why Guy’s cameo reads as more than a nostalgic nod.
Fillion’s character does not stop at ‘Superman.’ Guy Gardner is set to return for Man of Tomorrow, which is slated for a theatrical release on July 9, 2027. His recurring presence across the film and the series effectively turns him into connective tissue holding the corner of the DCU together.
Not every Lantern shares that same clarity of future. Hal Jordan remains the one Green Lantern whose fate beyond the TV show has not yet been confirmed for any future DC project. That ambiguity has already become a talking point among fans tracking where Gunn’s universe goes next.
John Stewart’s Road to ‘Man of Tomorrow’
While Guy Gardner supplies the direct crossover, John Stewart is the character carrying the emotional throughline of ‘Lanterns’ into the wider DCU. In March 2026, Deadline reported that Aaron Pierre had been cast in Man of Tomorrow, where he will be reprising his role as Stewart. That casting confirms the show is functioning as an origin story rather than a standalone detour.
The series appears designed with that future appearance in mind. John Stewart is confirmed to return in Man of Tomorrow, with the HBO series functioning as viewers’ first real introduction to the character ahead of his big screen appearance. Giving Stewart eight episodes to develop before his film debut is a notable departure from how DC has typically introduced supporting heroes.

The show’s fractured timeline reinforces that setup. In 2016, Hal and John are investigating a mass shooting in Rushville tied to an alien threat, with Hal having trained John for only two months at that point, while the timeline explored in the premiere jumps forward to 2026, when John returns to a snowy Rushville and finds Hal Jordan’s dead body. That structure suggests John’s arc in ‘Lanterns’ is meant to explain who he becomes by the time he reaches the big screen.
Chapter One Gods and Monsters Ties It All Together
‘Lanterns’ does not exist in a vacuum within Gunn’s DCU, and its connections extend well past two characters. However different Lanterns may look from Superman or the tonally distinct Peacemaker, it is part of the same DC Universe as those two projects, along with the animated Creature Commandos series and the Supergirl film arriving in theaters. That shared framework is what Gunn has branded Chapter One, Gods and Monsters.
Gunn himself has spoken about how deliberately these connections were built. In an October 2025 virtual press conference, Gunn confirmed that ‘Peacemaker,’ ‘Man of Tomorrow,’ and ‘Lanterns’ would all be linked by shared elements pulled from the comics, telling reporters the shows and films are more connected than they might initially appear, according to Variety.
That same intentionality carries into how Gunn talks about tone across projects. Lanterns is part of DC Comics’ reset officially branded Chapter One, Gods and Monsters, joining Superman, Supergirl and the upcoming Clayface as connected pieces of the same evolving universe, with Gunn telling Rolling Stone that even projects with wildly different tones are being built with an eye toward how they connect.
Together, these statements suggest ‘Lanterns’ was never meant to feel like a detached noir experiment. It is a deliberate piece of a larger puzzle that Gunn has been assembling since ‘Superman’ first hit theaters.
What the Show’s Supporting Cast Hints About the DCU’s Future
Beyond its two Lantern leads, the series is quietly seeding future storylines through its supporting characters. James Gunn, head of DC Studios, has emphasized that the series is really important in setting up things within the universe, and the supporting cast hints at major upcoming storylines. Exactly what those storylines are remains unconfirmed, but the speculation has already started.
One character in particular has drawn attention from longtime Green Lantern readers. Garret Dillahunt plays the mysterious cowboy William Macon, who many fans speculate will be revealed as Black Hand, an iconic Green Lantern villain who serves in the comics as the mortal anchor for Nekron, the embodiment of death, and a central figure in the Blackest Night storyline. If that theory holds, it would give ‘Lanterns’ a much larger cosmic footprint than its grounded crime drama exterior suggests.
Even setting aside any specific comic adaptation, the show’s world building has implications elsewhere. The Green Lantern Corps functions as an intergalactic police force that naturally connects to multiple corners of the DCU, and characters like Guy Gardner provide a narrative bridge linking franchises such as Superman and Peacemaker to whatever shape the Green Lantern side of the universe takes after Lanterns concludes. That framing positions the series as a foundation rather than a footnote.
With new episodes continuing to roll out, viewers now have a clear map of how ‘Lanterns,’ ‘Superman’ and ‘Man of Tomorrow’ are meant to fit together, and the bigger question left hanging is what happens to Hal Jordan once the season reaches its frozen Rushville ending, a mystery worth debating in the comments below.
