The upcoming Lanterns series is shaping the direction of James Gunn‘s Justice League in a significant way, according to early impressions from the show‘s debut teaser at HBO Max’s Upfront in São Paulo on November 25. Although the teaser hasn’t been released publicly, descriptions indicate that John Stewart’s role within the Green Lantern Corps is set to grow, making the focus keyword “James Gunn’s Justice League” central to this development.
Early Teaser Suggests a New Path for the Green Lantern Corps
The first teaser for Lanterns screened exclusively for industry insiders, hinting at an intriguing dynamic between Hal Jordan and John Stewart reminiscent of the procedural partnership found in True Detective. Both characters have reportedly been working together for several months in a rural setting, with their partnership shown as tense and competitive rather than following a traditional mentor-student relationship. The narrative appears to be framing John Stewart as the Green Lantern most likely to become part of the new Justice League under James Gunn’s vision.
In the footage, Hal Jordan assumes the position of a substitute trainer for John Stewart, temporarily filling a role previously held by another, though it remains unclear who that original mentor might have been. The teaser paints Stewart as a capable and assertive member of the Green Lantern Corps, feeling he may have already surpassed Hal’s skills. This setup implies that Stewart, as a determined and sometimes arrogant hero, stands prepared for a crucial turning point in his journey. The limited mentorship implies Hal’s involvement is fleeting, with John Stewart being developed as the central figure for the long-term DCU plans.
Showrunner Chris Mundy Highlights the Theme of Replacement
Chris Mundy, who leads the Lanterns series, described the show using a telling phrase:
“in a lot of ways about replacement,”
Mundy, Showrunner
He expanded on this core concept with a rhetorical question:
“When should someone step aside and when is it time for the next person to take the reins?”
Mundy, Showrunner
This direction is likely to reshape fan expectations, as many may have been anticipating a more prominent role for Hal Jordan. The story isn’t hiding its intentions: Hal Jordan’s purpose is transitional, intended to pave the way for John Stewart to take over as the main Green Lantern. In real-world terms, the casting—Kyle Chandler at 60 portraying Hal Jordan, and Aaron Pierre at 31 as John Stewart—underscores the generational shift. It signals the Justice League Gunn is building will focus on younger heroes positioned for enduring roles in the DCU.
James Gunn has underscored that Lanterns will significantly influence broader DCU developments. If John Stewart is truly the Green Lantern being prepared for leadership, his involvement in James Gunn’s Justice League becomes increasingly likely as the universe’s interconnected narrative expands.
John Stewart Set to Lead the Next Justice League Era
While Warner Bros. and DC Studios have not officially announced a fresh Justice League project, signs point toward its eventual formation. Previous DCU properties like Superman and Peacemaker season 2 introduced the Justice Gang, laying foundational storylines for future team-ups. James Gunn’s intention for a connected storytelling approach across the DCU makes John Stewart a natural candidate for the Green Lantern spot in any upcoming Justice League lineup.
Though Hal Jordan could theoretically join, the Lanterns teaser strongly indicates his time in the spotlight will be limited. Stewart is portrayed not only as younger, but as someone meticulously trained for high-stakes missions, making him ideal for the DCU’s long-term strategies. With Hal stepping aside, Stewart is lined up as the individual to uphold the Green Lantern mantle through the next phase of the universe, one that will inevitably see the formation of Gunn’s Justice League.
No official date has yet been set for the premiere of Lanterns, but it is anticipated to drop in the latter half of 2026. Fans awaiting more information on the future of the Green Lantern Corps and James Gunn’s Justice League will be watching closely as these developments unfold.
The Cast Bringing Lanterns to Life
Aaron Pierre will take on the role of John Stewart, the rising star among the Green Lanterns. Kyle Chandler steps into the role of Hal Jordan, the established hero serving as a transient guide. Supporting the main duo, Kelly Macdonald plays Sheriff Kerry, and Garret Dillahunt appears as William Macon. This ensemble sets the stage for a character-driven story that aims to reshape legendary parts of DC lore.
As anticipation builds for the Lanterns series, the future of James Gunn’s Justice League—and the place of John Stewart within it—remains one of the DCU’s most intriguing storylines.
