James Gunn has marked 65 years since Matt Hagen’s debut in Detective Comics #298 by spotlighting the performance at the center of the DCU’s Clayface. Gunn praised Tom Rhys Harries for finding the human cost within a story about a man becoming a monster, describing the performance as emotionally weighty and intensely personal.
That emphasis is telling. Clayface is a character built around transformation, but the most durable version of a transformation-horror story is not simply about the spectacle of a changing body. It is about what the person experiencing that change can no longer control, retain, or recognize. Gunn’s comments frame Harries’ Matt Hagen as the emotional point of entry for the film’s horror rather than merely the figure responsible for its most unnerving imagery.
“It’s one thing to watch someone become a monster, but another to feel everything that person is losing along the way,” Gunn wrote. “Tom Rhys Harries gives an astounding performance in Clayface, bringing an emotional weight to the horror in a way that feels incredibly personal.”
The timing also puts a useful focus on the specific Clayface behind the DCU film. “Clayface” is not a single, fixed comic-book identity; the concept predates Matt Hagen by decades, and several versions have appeared across comics, animation, games, and screen adaptations. Yet Hagen’s 1961 debut has become especially significant in the character’s broader legacy, and the DCU has chosen to build around him.
Why Matt Hagen matters to Clayface’s screen legacy
Matt Hagen is a shapeshifting Batman adversary, an idea with obvious visual appeal but also unusually flexible dramatic potential. Shapeshifting can be used for menace, deception, physical horror, or tragedy. A character who cannot maintain one stable form naturally raises questions about identity: who is the person beneath the changing exterior, and what happens when their body itself becomes unreliable?
That flexibility helps explain why Clayface has kept returning in different forms. The name can accommodate stories that play as heightened villainy, dark comedy, action, or horror. It also means that audiences may recognize the broad premise while encountering a substantially different version of the character depending on the adaptation.
For Hagen, the contemporary cultural foothold owes much to Batman: The Animated Series. Its two-part 1992 episode, “Feat of Clay,” helped popularize this iteration with viewers. The significance is not simply that the animated series used the character; it demonstrated that Clayface could hold a story with pathos as well as threat. That is an important throughline to Gunn’s focus on loss in the live-action film.
In other words, Hagen is not being treated as just another goo-covered obstacle for a Gotham hero to punch. The DCU’s approach, at least as described by its chief and reflected in the film’s premise, gives the troubled character the narrative center. That makes the horror personal: the frightening element is not only what Hagen can become, but what becoming it takes from him.
Horror, explained: transformation needs a human anchor
“Body horror” is a useful term here, even when a film’s full genre mix may be broader. It generally describes horror rooted in disturbing changes to the body: mutation, injury, loss of physical autonomy, or a breakdown between a person’s sense of self and their physical form. Clayface’s shapeshifting makes him a natural fit for that territory.
But technical effects or startling transformations alone are not enough to create sustained impact. If viewers only observe a creature changing shape, the sequence can remain distant. The horror becomes more immediate when it is connected to a character’s grief, fear, regret, or inability to stop what is happening. Gunn’s praise specifically identifies that connection in Harries’ work: the performance makes the audience feel the things Hagen is losing.
That distinction is valuable for a comic-book adaptation. Superhero worlds often train viewers to expect escalation, spectacle, familiar guest appearances, and neat links to a wider continuity. A horror story has different needs. It needs a perspective close enough to the suffering that the monster is not just a special effect. The claim that Harries supplies “emotional weight” suggests the performance is carrying that perspective.
There is a practical audience benefit to that approach, too. Viewers do not need deep familiarity with every Clayface incarnation to understand the basic stakes of a person confronting an unwanted transformation. Longtime DC followers can appreciate the choice of Hagen and the character’s screen history; newer audiences can follow a focused character tragedy.
The same principle is part of why horror can work well beyond cinema. Anyone interested in the genre as a social, table-ready experience might also want to see why Horrified makes a case for actually getting played on Halloween. The format is different, but the appeal is familiar: horror is often strongest when its monsters have a clear identity and the people facing them have something tangible at risk.
A DCU story that resists the automatic Batman cameo
Clayface occupies a strange but promising place in the DCU. Hagen is closely associated with Batman’s corner of Gotham, and Batman is said to be active in the city during the events of Clayface. Still, Batman does not appear in the film.
Director James Watkins addressed that absence by emphasizing the scale of Gotham and the film’s chosen focus. “It’s a city of a very many million people, and this is Matt Hagen’s story,” Watkins said. “I didn’t want to get too cute. I just wanted to be honest to the story.”
That response identifies a deliberate storytelling choice rather than a continuity oversight. Shared-universe storytelling can create the assumption that every plot must eventually be validated by a larger character’s arrival. In this case, the creative team appears to have prioritized a self-contained viewpoint: Gotham can be a setting with a famous protector without every crisis becoming Batman’s immediate narrative property.
There is a difference between a character existing in a shared universe and a character being required to dominate every story in it. Allowing Hagen’s film to remain Hagen’s film is a meaningful test for the DCU. If every Gotham narrative is obliged to summon the Caped Crusader, supporting characters and villains risk becoming little more than launchpads for a Batman appearance. Watkins’ explanation suggests Clayface avoids that trap.
It also supports the horror premise. Introducing Batman could shift the story’s center of gravity toward a familiar hero-versus-villain structure. Keeping the focus on Hagen leaves more room for uncertainty, deterioration, and the emotional experience Gunn highlighted. The absence may disappoint viewers expecting an overt Batman connection, but it is consistent with a film designed around a man’s transformation instead of a superhero’s intervention.
From Creature Commandos to live action
The DCU has not introduced this version of Hagen only through the film. The character appeared first in the animated series Creature Commandos, before Harries brought him into live action. That two-step path gives the universe a degree of continuity while also allowing the movie to make a distinct genre case for its lead.
Animation and live action ask different things from Clayface. In animation, a shapeshifter can be rendered with broad visual freedom, and the character’s changing form can lean into stylization. In live action, the same concept has to coexist with physical performance and with an audience’s expectation that the danger could feel more immediate. Gunn’s comments credit Harries with bridging that gap through character work rather than reducing the role to an effects showcase.
This is also a useful reminder that “DCU” does not have to mean one uniform tone. The supplied details place Clayface in a continuity that already includes animation, while the film itself is presented through a horror lens. The connective tissue is the character and setting, not a requirement that every entry look or feel identical. A shared continuity has more room to breathe when individual projects can select the genre best suited to their protagonist.
Other Clayfaces, other tones
Hagen’s anniversary should not erase the other identities that have used the Clayface name. Basil Karlo, for instance, remains a prominent screen version of the character. Alan Tudyk voices Karlo in Harley Quinn, where the character’s larger-than-life actor persona works with the show’s broad, comic energy. Karlo also appears in Batman: Arkham City.
Those examples illustrate the unusual adaptability of the Clayface concept. A Basil Karlo appearance in a comedic animated series can play very differently from a Matt Hagen-led horror film without either one invalidating the other. The shared name signals a recognizable corner of DC mythology; the particular identity, tone, and medium determine the experience.
For players, the Arkham City reference is a concise reminder that Clayface already has a place in Batman gaming history. For animation viewers, Tudyk’s Karlo shows how readily the character can support a heightened, theatrical performance. And for the DCU, Harries’ Hagen now represents a more intimate route: a troubled central figure whose frightening transformation is inseparable from personal loss.
What Gunn’s praise suggests about the film’s reception
Clayface has reportedly recouped its budget in its first weekend, making it a modest box-office success. That result matters because a character-focused horror approach is inherently more specific than a conventional, hero-led blockbuster formula. It places confidence in a less familiar lead and asks audiences to meet a Batman-associated villain on his own terms.
Gunn’s anniversary message does not disclose future plans, and it should not be read as confirmation of any particular sequel, crossover, or Batman appearance. What it does make clear is the quality DC Studios sees in Harries’ contribution. The praise centers on emotional specificity, not just the character’s powers, effects, or place on a franchise roadmap.
That is perhaps the strongest case for revisiting Matt Hagen 65 years after his debut. Clayface remains visually distinctive because he is mutable; he remains dramatically useful because that mutability can reflect a life coming apart. The DCU’s film has chosen the latter as its core concern. By praising Harries for making the loss feel personal, Gunn has articulated why a shapeshifting villain can sustain a horror story that is about more than the monster on screen.
