The Clayface Final Trailer Just Melted the Internet — Here’s Everything You Need to Know

The Clayface Final Trailer has arrived, and if you were hoping DC Studios would ease you into their first-ever horror movie with a gentle, PG-13 pat on the back, I regret to inform you: Matt Hagen has other plans, and most of them involve his own face coming off in creative new ways.

Warner Bros. and DC Studios dropped the Clayface Final Trailer on their YouTube channel this week, and within hours it had done what every good horror trailer should do — made a significant portion of the internet simultaneously say “I need to see this” and “why did I watch that at my desk.”

Let’s break down what’s actually in the trailer, what it confirms, what it’s still hiding, and why the Clayface Final Trailer might be the most unexpectedly ambitious thing DC Studios has done since James Gunn decided a raccoon deserved a redemption arc.

Wait, Who Is Clayface Again?

For the uninitiated: Clayface is one of Batman’s classic Rogues Gallery villains, a shapeshifting monster made of living clay who can mimic anyone’s face and form. This particular take, though, isn’t pulling from the comics directly — it’s partly inspired by the two-part “Feat of Clay” episode of the 1990s “Batman: The Animated Series,” which if you know, you know, and if you don’t, go watch it, it’s still terrifying thirty years later.

The film stars Tom Rhys Harries as Matt Hagen, and the Clayface Final Trailer wastes no time reminding us why this casting matters.

According to reporting from Vital Thrills, Matt Hagen’s meteoric rise from a Gotham street kid to a Hollywood leading man is cut tragically short when a local crime boss leaves him horribly disfigured. Desperate, he seeks out an experimental treatment that seems to fix everything — until it very much doesn’t.

What Actually Happens in the Clayface Final Trailer

Here’s the gist, pieced together from the footage and confirmed by multiple outlets: Matt gets access to an experimental face cream — yes, a face cream, this is somehow both the silliest and most body-horror-pilled premise DC has ever greenlit — that lets him remake his features for short stretches of time.

Naturally, “short stretches” turns into “permanently melting into a shapeshifting clay monster,” because that’s how these things always go in movies where the tagline isn’t “and everyone lived happily ever after.”

As Dark Horizons explains, the film is a standalone body-horror thriller written by Mike Flanagan and Hossein Amini, and Matt ultimately mutates into a walking creature of clay who can shapeshift into anyone at will, setting out for revenge.

Revenge against whom, exactly, is part of the fun the Clayface Final Trailer keeps mostly under wraps — but between the shattered mirrors, the melting bathtub scene fans have been talking about since the teaser, and a truly upsetting airplane sequence involving fused eyelids and a pair of scissors, “restraint” is not the word I’d use to describe this marketing campaign.

Per ScreenRant’s coverage of the new footage, the trailer leans further into Matt’s shapeshifting abilities and the horror elements, while also giving fans more glimpses of his full monster form — with DC Studios confirming that the classic comic-accurate Clayface design will actually appear in the finished, R-rated film. Star Tom Rhys Harries reportedly described the final look to Empire Magazine in blunt, five-star-review terms that I cannot fully reproduce here but can confirm involved a very enthusiastic profanity.

The Final Form Is Still a Secret (For Now)

Here’s the part that separates the Clayface Final Trailer from your average superhero preview: DC Studios is apparently sitting on Clayface’s complete final design like it’s the last slice of pizza at a party.

As ComicBookMovie points out, it’s been said that Clayface’s final form will be saved for theaters, meaning the design won’t be featured in any promotional material — a deliberate strategy that’s clearly designed to build anticipation while keeping the door open for potential leaks.

Honestly? Respect. In an era where every trailer shows you the entire third act, a studio choosing to withhold “guy turns into iconic clay monster” until you’ve paid for a ticket is either a masterstroke of old-school showmanship or a very expensive game of chicken with Reddit’s screenshot detectives. Either way, the Clayface Final Trailer plays coy about the big reveal, and it works.

Who’s In It, and Who’s Behind the Camera

The Clayface Final Trailer also reconfirms a genuinely stacked supporting cast: Naomi Ackie, Max Minghella, David Dencik, Eddie Marsan, Nancy Carroll, and Joshua James round out a film that, per Vital Thrills, has already secured its R rating from the MPA for strong bloody violence, gore, language, some nudity, and brief drug use — making it, notably, the first R-rated entry in the new DC Universe.

Behind the scenes, it’s a genre-lover’s dream team. James Watkins directs — the man behind Eden Lake, The Woman in Black, and the Speak No Evil remake, so nobody can say he doesn’t have receipts.

The screenplay comes from horror heavyweight Mike Flanagan (The Haunting of Hill House, Midnight Mass) alongside Hossein Amini, with Matt Reeves, Lynn Harris, James Gunn, and Peter Safran producing. Volker Bertelmann, fresh off scoring Conclave, handles the music — which, if the trailer’s unsettling remix work is any indication, is going to make theater sound systems earn their keep.

Per reporting from ComicBasics, Gunn has said he never actually planned to make a Clayface movie until Flanagan pitched the idea, and the script impressed him enough on a second pass that DC found a place for it in the lineup. Which tracks — it takes a genuinely great script to convince a studio to build its first R-rated superhero movie around a villain best known, historically, for being a guy with a slightly stretchy face.

Where Does This Fit in the DCU?

Good question, and the Clayface Final Trailer doesn’t fully answer it — by design. Clayface is officially part of Chapter One: Gods and Monsters, DC’s ongoing universe plan, and it’s positioned as the third theatrical release following Superman and Supergirl.

But according to GeekTyrant, the film is largely self-contained within Gotham City and apart from the DCU’s bigger events, Batman himself won’t appear, though Bruce Wayne is reportedly mentioned, and the movie is expected to shed light on Clayface’s connection to Creature Commandos.

So don’t expect the Clayface Final Trailer to double as a Batman teaser. This is Gotham’s underbelly, not the Batcave — and honestly, letting a horror director make a horror movie without shoehorning in a cameo is the kind of restraint DC deserves credit for.

What the Internet Is Saying About the Clayface Final Trailer

As with any good horror marketing campaign, reactions are split between “sign me up immediately” and “this might be too much, even for me.” Looper rounded up early fan responses noting that viewers were caught off guard by grotesque imagery they weren’t expecting, with one commenter calling it a worthy substitute for getting introduced to Batman’s corner of the DCU through horror instead.

Not everyone’s fully on board with the tone, though. SuperHeroHype reported that some fans on X have debated whether the trailer veers into “torture porn” territory, while others insist it doesn’t feel like a typical Gunn-produced film and are more intrigued because of it.

And per ComingSoon.net, several viewers drew comparisons between the trailer’s tone and films like Darkman, The Substance, and The Fly — which, if you’re a body-horror fan, is basically the “instabuy” trifecta.

Meanwhile, Nerdist went so far as to call this the strongest marketing beat of the campaign, noting that the final trailer shows Matt Hagen not just embracing his new powers but fully embracing his monstrous side, in a movie poised to bring genuine horror to the DCU. High praise for a guy whose superpower is, functionally, “worst skincare routine imaginable.”

The Bottom Line on the Clayface Final Trailer

Here’s what the Clayface Final Trailer actually proves: DC Studios didn’t just slap a horror label on a superhero movie and call it a day.

Between Flanagan’s script, Watkins’ genre pedigree, an R rating DC has never touched before, and a marketing team disciplined enough to keep the final monster design under lock and key, this feels like a real swing at something different — not a cash-in on a lesser-known villain’s name recognition.

Clayface hits theaters in North America on October 23, with an international release beginning October 21, and if the Clayface Final Trailer is any indication, you should probably see it with people you don’t mind grabbing your arm during the bathtub scene.

Whether Matt Hagen ends up as one of DC’s most tragic anti-heroes or its scariest new monster, one thing is certain: this is not the DCU movie anyone expected, and that might be exactly the point.
