The new DC Universe is already proving that James Gunn is not interested in letting the franchise settle into one familiar rhythm. After launching with Creature Commandos in December 2024, the DCU moved through Superman, Peacemaker Season 2, Supergirl, and Lanterns, each project pushing the universe into a different corner of the genre spectrum. Now, Gunn is preparing to bring Clayface into theaters on October 23, 2026, with the latest DCU chapter leaning heavily into horror.

For Gunn, Clayface is an especially revealing project because it was not part of the original DCU roadmap. Mike Flanagan pitched the idea to DC Studios, and Gunn has said the screenplay was strong enough that he and Peter Safran would have wanted to make it even if it had not been a DC project. That history makes Gunn’s latest update particularly intriguing.

James Gunn took to X to share the latest word on the movie, keeping his message characteristically brief while giving the film a suitably ominous tease. 

“You’ve never met anyone like him,” he wrote.

He then confirmed that Clayface will arrive exclusively in theaters on October 23. The post immediately puts the emphasis on the character rather than the wider DC mythology, which fits a movie designed to work as a horror story as much as a comic book adaptation.

The timing also gives the update extra weight. Gunn discussed Clayface on the DC Studios Showcase Official Podcast, explaining that Mike Flanagan’s script impressed him and Peter Safran enough that they would have wanted to make it even outside the DCU. He described the project as an “amazing body horror film,” as Popverse reports. Flanagan was eventually replaced as director by James Watkins because of scheduling, while Hossein Amini worked on the screenplay alongside Flanagan.

Gunn has also pushed back against reports that the film was being radically rewritten, stressing that Flanagan’s story remained the reason the movie was being made.

Clayface essentially crashed the party because its script was too good to ignore. It also gives Gunn an opportunity to demonstrate one of the central ideas behind his DCU: the shared universe can accommodate radically different filmmaking languages.

The shift is significant because Clayface is not simply another superhero adventure with darker lighting. James Watkins, the director of Speak No Evil, is approaching the material as a horror thriller, while Tom Rhys Harries plays Matt Hagen, an ambitious actor whose life is shattered after he is horribly disfigured. A cutting-edge treatment restores his appearance, but the procedure comes with a horrifying cost, sending him toward a destructive transformation.

That premise puts Clayface closer to classic body-horror cinema than conventional cape fare. The trailers have already foregrounded melting flesh, distorted features and the grotesque physical consequences of Hagen’s transformation, while Gunn has openly connected the project to his own horror background, including Slither. Flanagan has also drawn inspiration from the famous two-part Batman: The Animated Series story Feat of Clay, giving the film a comic-book lineage without trapping it inside a familiar superhero template.

The result could become one of the most distinctive experiments in the early DCU. With Clayface arriving October 23, Gunn is not merely adding another villain to the universe. He is testing how far a DC movie can stretch before the superhero label stops being the dominant genre.
