James Gunn Shuts Down Man of Tomorrow’s ‘Secret Character’ Rumors: ‘Most Stuff Is Just Dead Wrong’

James Gunn shut down the Man of Tomorrow secret characters rumors himself on Tuesday, September 15, 2026, posting on Threads that his Superman sequel is “a movie about Lex and Clark” and that fans shouldn’t expect substantial new characters or screen time beyond Brainiac. It’s a direct statement from DC Studios’ co-CEO, not a leak.

Gunn posted it himself, unprompted by any studio press push, straight into a Threads reply thread on Tuesday, September 15, 2026 — not a leaked call sheet, not an anonymous “source close to production,” but the co-CEO of DC Studios typing his own correction in real time. GamesRadar, ScreenRant and ComicBookMovie all picked up the exchange within hours.

What Gunn Actually Wrote (It Was Two Separate Posts)

This wasn’t one tidy soundbite. A fan asked Gunn point-blank about the wave of “secret character” rumors swirling around Man of Tomorrow, and Gunn answered directly:

What secret characters? It’s movie about Lex and Clark. People shouldn’t expect substantial amounts of other characters.

When someone pushed back and asked what he meant by “substantial amounts,” Gunn came back with a second, separate post that actually got specific:

When I say substantial amounts I mean both the amount of new characters and especially the time onscreen of characters who weren’t core characters from Superman (well other than Brainiac). Things have been blown way out of proportion, and most stuff is just dead wrong.

What’s Actually Confirmed for Man of Tomorrow

Strip away the rumor mill and here’s what’s real. Man of Tomorrow is a direct sequel to 2025’s Superman, written and directed by Gunn, releasing July 9, 2027. It’s the fourth film in the current DC Universe. Production ran roughly 5 months, from April through August 2026, shooting primarily at Trilith Studios in Georgia.

That’s the entire confirmed character list. Everything else — every Green Lantern tease, every Blue Beetle rumor, every “leaked set photo” thread — is speculation Gunn is now telling people to drop.

What Gunn’s Words Actually Rule In vs. Rule Out

Here’s the part worth reading closely, because it’s narrower than a flat denial. Gunn didn’t say “no other characters, period.” He said not to expect “substantial amounts” of new characters or screen time for anyone who wasn’t already core to 2025’s Superman — and he explicitly carved out an exception: Brainiac, whom he lists as already accounted for. That phrasing leaves room for a brief appearance or two from someone else without contradicting anything he wrote; what it rules out is a movie stuffed with new faces getting real screen time. The rumor mill had been selling the second thing. Gunn is only denying that.

It’s also a rarer move than it looks. Most studios let a rumor cycle run its course and either confirm everything at a trailer drop or say nothing at all. Gunn has now done this twice in a matter of weeks — he also personally shut down claims that Batman: The Brave and the Bold was on hold rather than letting that story sit unanswered. A chunk of the coverage feeding these rumor cycles, on this site and others, has been built on unconfirmed leaks with no primary source behind them at all; a direct Threads reply from the person actually making the movie is about as primary as sourcing gets.

Why the Rumor Mill Got This Loud in the First Place

The speculation didn’t come from nowhere. Fan forums and rumor sites have spent weeks naming Green Lantern, Blue Beetle and other DC heroes as possible Man of Tomorrow cameos, feeding off the fact that 2025’s Superman itself packed in a surprisingly large supporting cast for a film ostensibly about one hero. Gunn’s own packed DCU release slate — Supergirl, Clayface, Peacemaker Season 2 and more all moving at once — gives that kind of speculation an easy foothold, since there’s always another DC project a rumored character could theoretically be borrowed from.

None of that makes the rumors true. It just explains why they spread. Gunn’s answer is the correction, not a confirmation of anything new.

Frequently Asked Questions

What did James Gunn actually say about secret characters in Man of Tomorrow?

On Threads on Tuesday, September 15, 2026, Gunn wrote: “What secret characters? It’s movie about Lex and Clark. People shouldn’t expect substantial amounts of other characters.” When asked to clarify, he added that he meant both the number of new characters and their screen time for anyone who wasn’t already core to 2025’s Superman, Brainiac excepted, and called the online speculation “blown way out of proportion.”

Does Gunn’s statement rule out any new characters appearing at all?

Not entirely. Gunn specifically said not to expect “substantial amounts” of new characters or screen time for non-core characters, and he named Brainiac as an exception already built into the story. That leaves room for a brief appearance without contradicting what he wrote; it rules out a film packed with new faces getting real screen time.

Who is confirmed to appear in Man of Tomorrow?

David Corenswet as Superman, Nicholas Hoult as Lex Luthor, Rachel Brosnahan as Lois Lane, and Lars Eidinger as Brainiac. James Gunn is writing and directing. No other characters have been confirmed.

When is Man of Tomorrow released, and when did it film?

Man of Tomorrow is set for release on July 9, 2027. Filming ran from April through August 2026, primarily at Trilith Studios.

Why were fans expecting secret characters in Man of Tomorrow?

Weeks of rumor threads and fan speculation named Green Lantern, Blue Beetle and other DC heroes as possible cameos, partly because 2025’s Superman itself featured a large supporting cast and DC Studios currently has multiple projects in production that a rumored character could theoretically cross over from.
