James Gunn fired back on Twitter with a single word, “Nope,” to squash talk of Wonder Woman popping up in Man of Tomorrow. The chatter started back in November 2025 when insiders hinted at casting a tall, tough female warrior for the Superman follow-up, sparking wild guesses about Diana Prince crashing the party.
Fans latched on because the description screamed “Amazon princess,” complete with height specs and a battle-ready vibe that matched comic lore perfectly.
Gunn stayed true to form, dodging specifics as he did with the Brainiac reveals earlier. He never flat-out denied a big female hero role, just nixed the January 2026 casting drop fans were hyping.
Man of Tomorrow locks in for July 9, 2027, pitting David Corenswet’s Superman against Nicholas Hoult’s Lex Luthor in a team-up against some massive new foe. Early leaks point to Brainiac as the android menace, with Gunn stressing the core clash between Clark’s hope and Lex’s ruthless drive.
This shutdown fits Gunn’s playbook of letting rumors simmer before dropping facts, much like confirming Lars Eidinger as the cold collector villain only after chatter died down.

Social media exploded anyway, with DC fans parsing that “Nope” like a cryptic Bat-signal. Production kicks off in spring 2026, so more cast news could trickle out soon, but Gunn controls the drip.
Rumors Fueled by DCU Casting Frenzy
The fire under these rumors traces to late 2025 scoops claiming DC Studios hunted “young, hot” talent for a lead spot in Man of Tomorrow. Podcaster John Rocha amplified it, saying his sources pegged the role as Wonder Woman herself, with auditions drawing A-listers.
That buzz collided with fresh reports of Ana Nogueira scripting a standalone Diana flick, building hype that her debut might fast-track via Superman’s spotlight.

ComicBookMovie and similar sites ran wild with threads on actress wishlists, from Vikings stars to rising Hollywood names fitting the warrior mold.
Gunn had teased Wonder Woman’s priority status alongside Superman, Batman, and Supergirl as DCU pillars, per Warner Bros. Discovery boss David Zaslav. Yet he clarified that those four anchor the franchise without boxing out others, keeping options open.
No panic set in because Gunn’s history shows he engages fans directly, like debunking Steve Trevor’s casting or height debates for Diana.
Man of Tomorrow already packs Hawkgirl, Mister Terrific, and Green Lantern returns from the first Superman, plus Metamorpho is teased, so cramming another icon risked overcrowding. Rumors thrived on that crowded canvas, but Gunn’s response reset expectations without killing all intrigue.
Diana’s Real Path in Gunn’s DCU Vision
Wonder Woman stands firm as a DCU cornerstone, with Nogueira’s script underway for her own blockbuster. Gunn name-dropped the project in summer 2025 interviews, signaling no stall after initial slate silence. Zaslav’s pillar list underscores her weight, though release lags behind Supergirl in 2026 and The Batman Part II.
Gunn’s Entertainment Weekly chat revealed personal stakes: those four characters shape Chapter 1: Gods and Monsters, with Superman and Supergirl locked and Batman and Diana in progress.
A Paradise Lost prequel series adds layers, probing Themyscira’s power plays before Diana hits screens. Casting stays under wraps until scripts gel, ruling out rushed announcements.
Man of Tomorrow spotlights Superman-Lex dynamics against a “much bigger” threat, per Gunn, leaving room for the Justice Gang to expand without forcing crossovers.
Fans crave Diana’s live-action reset post-Gal Gadot, but Gunn prioritizes story fit over fan service. As production ramps, expect teases on her solo arc, maybe tying into broader threats like Brainiac’s world-shrinking schemes.
This rumor cycle highlights DCU’s momentum post-Superman’s box office win, where every leak sparks Justice League dreams. Gunn’s direct style builds trust, turning potential flops into fan fuel.
Diana waits in the wings, primed for her moment when stars align. Man of Tomorrow rolls on without her, but the DCU’s hero roster grows smarter.
