The DC Studios co-chair has spent the past week turning the "Superman: Legacy" shoot into a rolling content machine, and fans cannot look away.
New set photos from Cleveland show David Corenswet in the full red-and-blue suit, cape snapping in the wind, and the internet has already declared it the most comic-accurate Superman costume since Christopher Reeve.
What set this apart wasn't the suit itself.
It was Gunn posting the images himself, casually, like a guy sharing vacation pics.
For years, DC kept fans at arm's length with cryptic teases and studio-approved stills.
Gunn is doing the opposite, feeding the beast in real time.
Then came the bigger curveball: a first look at Nicholas Hoult as Lex Luthor, bald and scowling, and the confirmation that this film isn't a solo Superman story at all.
The cast list reads like a Justice League starter pack.
Nathan Fillion as Guy Gardner, Isabela Merced as Hawkgirl, Edi Gathegi as Mr.
That's a universe launch disguised as one.
Fans have spent the week fighting about it.
Some argue Gunn is cramming too much into one film, repeating the exact mistake that sank "Batman v Superman." Others point out that Gunn built the Guardians of the Galaxy from a talking raccoon and a tree, so maybe trust the guy who already pulled off the impossible.
The debate has been loud enough to trend on X for three straight days.
There's also the timing. "Superman: Legacy" lands July 11, 2025, and it's the first real test of Gunn's rebooted DC slate.
Hollywood has a short memory and a long grudge.
Meanwhile, the behind-the-scenes chatter is just as juicy.
Reports suggest Gunn is running a tight, almost indie-style set, with fewer studio fingerprints than the Snyder-era productions.
Insiders describe long days and a director who rewrites scenes on the spot.
That's either visionary or chaotic, depending on who you ask.
And then there's the fandom crossover nobody expected.
Marvel fans who swore off DC are suddenly paying attention, partly because Gunn's Guardians trilogy earned genuine goodwill and partly because the man knows how to post.
His social media game might be the most valuable marketing asset Warner Bros. has right now, and it's free.
The real question isn't whether the suit looks good.
The question is whether one director can carry an entire cinematic universe on his back while still making a movie that stands on its own.
Gunn has bet his reputation on the answer being yes. **Our take:** Gunn is doing something the old DC regime never figured out, which is treating fans like people instead of focus groups.
That alone won't save the film if the script is weak, but it's bought him enormous goodwill heading into next summer.
Final Thoughts
If "Superman: Legacy" delivers even half the buzz these set photos generated, DC finally has a pulse again.
