Lars Eidinger cast as Brainiac — James Gunn makes it official

James Gunn has closed weeks of online speculation by announcing the actor chosen to play Brainiac in Man of Tomorrow. In a post on X (formerly Twitter), the writer-director revealed that after a global search the production settled on German actor Lars Eidinger. Gunn’s pick arrives straight from a desire to match the role’s cold intelligence and theatrical menace, and fans are already debating what this means for the new DC timeline.

Why Eidinger is an intriguing choice

Eidinger is best-known to international audiences for his turn in Babylon Berlin, and his résumé ranges from European art-house intensity to mainstream collaborations — he’s worked with directors like Shawn Levy on Netflix’s All the Light We Cannot See and Noah Baumbach on White Noise. That blend of gravitas and unpredictability makes him a compelling Brainiac: a villain who’s not merely a physical threat, but a calculating, almost clinical antagonist.

Brainiac is one of Superman’s oldest foes, first appearing in Action Comics #242 (1958), created by Otto Binder and Al Plastino. Traditionally depicted as a hyper-intelligent alien who shrinks and bottles cities, Brainiac’s menace is cerebral as much as it is cosmic — the kind of villain that forces heroes to rethink tactics and alliances. In comic arcs over decades, Brainiac’s threat level has occasionally been so severe that even Lex Luthor and Superman found themselves uneasy partners.

Where Man of Tomorrow fits in the DC puzzle

Man of Tomorrow is a direct sequel to this summer’s Superman and brings David Corenswet back in the cape, with Nicholas Hoult returning as Lex Luthor. Rumors suggest the film will push the uneasy Luthor–Superman dynamic toward a temporary alliance to face a larger existential threat — Brainiac. James Gunn wrote and directed the sequel and will produce alongside Peter Safran, steering DC Studios’ new vision for the franchise.

The film’s release date is set for July 9, 2027, guaranteeing a fast turnaround compared to recent Hollywood sequels slowed by the pandemic and strikes. Gunn’s hands-on approach — as writer, director, and public-facing promoter — signals the studio’s intent to move quickly on world-building while keeping a distinct creative voice.

Comparisons and potential tone

Expect a different Brainiac than animated or small-screen versions; Gunn’s films (and his work on Peacemaker) balance dark humor, character-driven stakes, and operatic set pieces. Think of Eidinger’s Brainiac as less a comic-book trope and more a chilling strategist — somewhere between the clinical cruelty of an old sci-fi villain and the charismatic menace modern audiences respect.

Fans reacted quickly on social channels: many praised the casting for ambition and nuance, while others wondered if a largely European arthouse actor can anchor a blockbuster calamity. That debate is part of the fun — and part of modern fandom’s role in shaping expectations.

"Eidinger brings a theatrical intensity that can deepen Brainiac beyond spectacle," says cinema historian Marco Santini. "His background suggests a version of the character that will be intellectually threatening as well as visually striking."

Whether this Brainiac becomes a franchise-defining antagonist will depend on Gunn’s vision and how the film balances spectacle with the darker, philosophical threat Brainiac represents. For now, DC fans have a provocative new face to watch as production accelerates toward summer 2027.
