‘Clayface’ Brings Body Horror to Gotham as James Watkins Explains Surprise Cameo

“Clayface” is bringing a horror-led vision of Gotham City to the rebooted DC Universe, with director James Watkins placing a Batman antagonist rather than the superhero at the center. The R-rated film follows Matt Hagen’s transformation into a shape-shifting killer and includes a fleeting appearance by Aaron Paul. Spoilers follow for the film, now playing in theaters.

Tom Rhys Harries stars as Hagen, whose journey begins far from conventional superhero spectacle. According to DC’s official synopsis, he rises from a Gotham street childhood to Hollywood stardom before a local crime boss leaves him severely disfigured, abruptly destroying the life he has built.

Abandoned by his team, Hagen seeks an advanced treatment that restores his appearance but also destabilizes his sense of reality. What initially seems like a route back to his former life instead sends him toward revenge. His changing body becomes central to both the film’s horror and its portrait of a man losing control.

Paul’s appearance connects that transformation to Hagen’s family history. The actor briefly plays Hagen’s father, whose face emerges during a shape-shifting sequence near the end of the film. The moment is part of Hagen’s violent confrontation with the criminal world, rather than an introduction to another costumed DC character.

Watkins told Entertainment Weekly that Paul originally had a larger role, including flashback material involving a younger Hagen. Much of that footage was removed as the filmmakers reconsidered how strongly the protagonist should be defined by his childhood. The surviving appearance is therefore a remnant of a more extensive exploration of his past.

That editorial choice keeps the emphasis on Hagen’s immediate collapse and desire for retribution. Rather than explaining every action through an extended family backstory, the finished film follows the consequences of his attempted physical restoration. The cameo retains a connection to that history without stopping the story for a lengthy flashback.

The Gotham setting also gives the film significance beyond its central monster. As Variety’s introduction notes, this is a glimpse of the rebooted DC Universe’s city, distinct from the Batman saga associated with Matt Reeves and Robert Pattinson. Viewers are encountering that setting through a villain’s experience rather than another account of the Caped Crusader.

In a studio-published interview, Watkins emphasized the importance of emotional involvement alongside frightening imagery. He described wanting audiences to care about Hagen before the story takes him into darker territory. That approach frames the transformations and killings as part of a character’s deterioration, not simply a succession of effects-driven shocks.

The screenplay is credited to Mike Flanagan and Hossein Amini, with the story credited to Flanagan. DC lists Naomi Ackie, David Dencik, Max Minghella and Eddie Marsan among the supporting cast. Warner Bros. released the film in North American theaters on October 23, following the start of its international rollout on October 21.

For now, the filmmakers’ stated emphasis remains on Hagen’s tragedy rather than promises about his next appearance. Watkins’ account of the editing process and his focus on emotional horror position “Clayface” as a character-led entry into the larger universe. Its theatrical release gives audiences their first opportunity to judge how that approach reshapes Gotham on screen.
