The DC Universe is taking a bold and chilling turn. James Gunn’s new cinematic continuity, the DCU, is already known for its creative risks and fresh takes on iconic heroes. However, its upcoming ‘Clayface‘ movie might just be its most daring step yet. With acclaimed horror filmmaker Mike Flanagan penning the script and director James Watkins behind the camera, the film promises to blend superhero storytelling with true psychological horror.
The project has been quietly filming in London since August 2025. It focuses on the tragic transformation of actor Matt Hagen, played by White Lines star Tom Rhys Harries. Moreover, Hagen’s descent into monstrosity and madness marks a rare opportunity for the DCU to explore the darker.
James Gunn’s DCU Expands With A Chilling New Vision Of Gotham In ‘Clayface’
During a recent interview with Collider, actor Max Minghella, who joined the cast in an undisclosed role, shed light on what fans can expect from the film’s tone. Currently filming in London, Minghella didn’t mince words about what kind of experience ‘Clayface’ is shaping up to be. “I think I can say safely it’s going there, it’s a proper movie,” Minghella teased, emphasizing the film’s commitment to horror. “It’s a really fantastic script.”

His comments align with James Gunn’s earlier statements confirming that the film will be R-rated, making it the first official R-rated entry in the DCU timeline. It’s a significant creative choice. Moreover, it signals Gunn’s willingness to let filmmakers explore mature themes without compromise. In the world of Gotham, Clayface’s story fits that mold perfectly. Unlike many of Batman’s villains, Matt Hagen isn’t driven by greed or chaos; he’s a victim of his own ambition.
Once a celebrated actor, Hagen’s life unravels when an experimental treatment disfigures him beyond recognition. It transforms him into a monstrous, shape-shifting being who can mimic anyone’s face but can no longer find his own. With Watkins’ direction and a modest $40 million budget, the creative team seems determined to make ‘Clayface’ feel intimate yet terrifying. With the film slated for a September 11, 2026, release, it seems poised to continue that momentum while expanding the tonal range of the DCU. If successful, it could become the Joker of Gunn’s shared universe.
James Gunn’s Warning About Gotham City Set Photos
As filming continues in Liverpool, standing in for Gotham City, fans have flooded social media with set photos and speculation about what the movie reveals about the DCU’s version of Batman’s home turf. They noticed details like maps marking Wayne Manor, Wayne Tower, and Wayne Industries, suggesting that Bruce Wayne already exists in this timeline. Others spotted posters referencing Gotham’s other famous criminals, such as “Penguin Man” and a possible mention of the Joker.

Naturally, excitement went through the roof. However, James Gunn was quick to temper expectations. Speaking with IGN, the DC Studios co-chief made it clear that fans shouldn’t assume every Easter egg is canon. “You really have to take it as something the art department put together,” Gunn clarified. “There are a couple of things I don’t even think were on the set, like that bat insignia. Somebody might’ve added that afterward.”
He went on to explain that while the film’s production design team has creative freedom, there’s an internal DCU “Bible” that ensures consistency across all projects. “We have a guy, Phil, who’s now in charge of the DCU Bible, keeping everything consistent, making sure the cities, maps, and even celebrities are the same,” Gunn said. “I don’t think he’s OK’d all the art department stuff on that movie.”
So for now, those Gotham details, while fun, are just that: details. They don’t necessarily confirm when Clayface takes place in the DCU timeline or whether Batman will appear. Still, the possibility of subtle world-building is exciting. Even if Batman himself doesn’t show up, ‘Clayface’ could serve as a haunting introduction to Gotham’s underbelly. And if Max Minghella’s comments are anything to go by, it’s not pulling any punches.
