Man of Tomorrow: Everything We Know About James Gunn's Superman Saga

James Gunn is expanding the DCU with a new chapter that centers on Superman and a brand-new dynamic with Lex Luthor. Since Gunn’s take on the Man of Steel began with a highly-rotated reception and strong global box office, fans are eagerly awaiting the next installment that promises to tilt the universe toward a broader, interconnected slate.

Man of Tomorrow release date: When’s it out? The next chapter, titled Man of Tomorrow, is set to hit theaters on July 9, 2027 — exactly two years after the original Superman debut. Gunn shared the release window alongside a Jim Lee-drawn image depicting Superman leaning against a flamboyantly suited Lex Luthor. The date pins 2027 as a landmark year for DC, with The Batman Part II scheduled for a fall release and marking a year in which both iconic franchises have stand-alone films.

Production notes hint that principal photography will begin in April 2026, a detail Gunn confirmed in September 2025 during an appearance on Howard Stern’s show.

Man of Tomorrow cast: Who’s in it? Soon after Gunn’s announcement, the film’s casting became a talking point. David Corenswet is positioned to return as Superman, with Nicholas Hoult stepping into the role of Lex Luthor. News also broke that Aaron Pierre has joined the cast as John Stewart, a member of the Green Lantern Corps.

Pierre’s casting ties into a broader arc: he’s already featured in the Lanterns series alongside Kyle Chandler as Hal Jordan, who mentors Stewart while they tackle a cosmic mystery unfolding in Nebraska. The project’s future, including Hal Jordan’s fate within the DCU, remains to be seen.

Actress Isabela Merced, who has been linked to Hawkgirl, shared Gunn’s post with excitement, while Frank Grillo signaled that his character, Rick Flag Sr., will be a central figure in the sequel’s plot. Additional names confirmed for Man of Tomorrow include Lars Eidinger as Brainiac and Lars Eidinger’s depiction of the villain was revealed earlier via Gunn’s announcements.

Confirmed cast list:

• David Corenswet as Superman
• Nicholas Hoult as Lex Luthor
• Aaron Pierre as John Stewart
• Isabela Merced as Hawkgirl
• Frank Grillo as Rick Flag Sr.
• Lars Eidinger as Brainiac

Rumors have swirled about potential cameos from Supergirl and Peacemaker, both of whom popped up in the preceding Superman film, and Jason Momoa’s Lobo has been floated as a possible addition to the story given his DCU trajectory. There’s also talk that some familiar faces from Superman — like Lois Lane, Perry White, Jimmy Olsen, and Eve Teschmacher — might appear in supporting roles, along with a host of meta-humans introduced in the earlier film, plus Krypto.

Man of Tomorrow villain: Who is playing Brainiac? In December 2025, Gunn confirmed Lars Eidinger would embody Brainiac, a villain whose comic-book history centers on seeking universal knowledge and miniaturizing civilizations for his private collection. Eidinger described his performance as one that won him the role after a standout audition.

Brainiac’s portrayal blends noir intellect with otherworldly menace, positioning him as a galaxy-spanning threat who could force Superman and Lex Luthor to team up in surprising ways.

Man of Tomorrow plot: What’s it about? Man of Tomorrow is described as a collaborative mission between Superman and Lex Luthor as they confront a threat that is larger than either hero realized. Gunn has characterized the film as both a Lex Luthor-centric project and a Superman-driven story, emphasizing the uneasy alliance between the two as they navigate a danger that could redefine the DCU.

To paraphrase Gunn’s own description on Howard Stern, the film centers on the unusual partnership between Superman and Lex, as they unite against a truly cosmic adversary. It’s a story that leans into Luther’s ambition and intellect, presenting a broader, more intricate problem than a straightforward superhero brawl.

In terms of the broader DCU, Man of Tomorrow may not be a direct sequel to Superman, but it is expected to feature several characters from that film and to weave in supporting players such as Lois Lane, Perry White, Jimmy Olsen, and Eve Teschmacher, along with a gallery of meta-humans introduced in the previous installment. The presence of Krypto is also anticipated as part of the film’s expansive world.

Who is the Man of Tomorrow? The title “Man of Tomorrow” is a Superman-aligned moniker, but some analysts speculate it could reference Lex Luthor’s own vision for humanity’s future—a meta-narrative angle where Luther sees himself as the architect of a future that he believes will surpass Superman’s influence. In the DCU, Luther’s intellectual confidence and self-styled role as humanity’s savior create fertile ground for him to redefine what the “Man of Tomorrow” means within a universe on the cusp of transformative threats.

As fans wait for July 2027, the DCU lineup continues to unfold with new films and series, enriching a universe that promises to blend familiar heroes with bold, new mythologies.
