James Gunn’s Batman spin-off film, Clayface, has confirmed six lead actors as it moves toward its release on September 11 this year. This movie marks an early step in expanding the Gotham world within Gunn’s vision for the DC Universe (DCU), although his full portrayal of Batman remains in progress. Clayface focuses on one of Batman’s darkest villains, introducing viewers to a new narrative in live-action for the first time.
Initially excluded from Gunn’s 10-year DCU roadmap, this Batman spin-off has become the third theatrical installment following 2025’s Superman and 2026’s Supergirl. Directed by James Watkins and written by Mike Flanagan alongside Hossein Amini, the film promises a diverse and talented cast to bring the story to life.
Lead Actor Tom Rhys Harries as Clayface
British actor Tom Rhys Harries has been cast as Clayface, portraying Matt Hagen, the central figure of the film. Before joining the DCU, Harries was known for roles in “White Lines,” “The Gentlemen,” and “Suspicion.” Clayface is depicted as a complex antagonist who transforms after a violent confrontation and a chemical accident, gaining shapeshifting abilities that allow him to assume any form he imagines.
Role of Naomi Ackie as Dr. Caitlin Bates
Naomi Ackie joins the cast playing Dr. Caitlin Bates, a character created specifically for this movie without prior comic book origins. Ackie previously appeared in films such as “Mickey 17,” “Lady Macbeth,” and “Blink Twice,” and is recognizable from Star Wars Episode IX as Jannah. Dr. Bates is described as Matt Hagen’s love interest and leads a cutting-edge biotech company focused on advanced medical research, hinting at a pivotal role in the story’s development.
Max Minghella to Portray Detective John
Max Minghella will take on the role of Detective John, an original character crafted for this film. Known for his work in “Spiral,” “Babylon,” “The Social Network,” and “The Handmaid’s Tale,” Minghella’s character is engaged to Dr. Caitlin Bates and grows wary of her relationship with Matt Hagen. This detective’s involvement is expected to shine a light on the Gotham Police Department and add layers of intrigue to the plot.
Unconfirmed but Rumored Role of Eddie Marsan
Eddie Marsan’s participation is rumored to be that of Matt Hagen’s manager, though this remains unconfirmed. Marsan carries a notable acting résumé, including “The World’s End,” “21 Grams,” and “Happy-Go-Lucky.” Set photos have captured him near a hospital giving a press event, supporting the theory that he will play an influential role during Hagen’s physical and psychological transformation.
Emerging Talent Emily Florence in an Undisclosed Role
Emily Florence has been announced as part of the Clayface cast, marking her first major film role after a career on the U.K.’s West End stage since 2013. She is currently involved in the BBC’s
“A Good Girl’s Guide To Murder.”
Details about her character in Clayface remain under wraps.
Wil Coban Cast as the Mysterious Bones
Wil Coban, who has previously appeared in “The Boys in the Boat,” “The Sandman,” and “Zack Snyder’s Justice League,” will portray a mysterious character known as Bones. This marks one of Coban’s most prominent roles to date. He is also slated to appear in the upcoming 2026 Supergirl film, linking multiple projects within James Gunn’s DCU.
Clayface’s Place in James Gunn’s Expanding DC Universe
As the third theatrical release in James Gunn’s DC lineup, Clayface is notable for focusing on a villain rather than a hero. The story will explore Matt Hagen’s origin as a struggling actor who undergoes a dramatic transformation into a shapeshifting monster, one of Batman’s most menacing foes. This character-driven plot is poised to add depth to the Gotham setting and expand the larger DC narrative.
James Watkins’ direction, combined with the screenplay by Mike Flanagan and Hossein Amini, promises an atmospheric and thrilling portrayal that reflects the complex emotional and physical changes Clayface experiences. The film’s cast, featuring both established and emerging actors, is anticipated to bring nuance and intensity to this darker corner of the DC Universe.
Looking Ahead: What Clayface Means for the DC Universe
The upcoming Clayface movie signals a willingness within the DC Universe to explore stories from the perspective of villains and lesser-known characters, broadening the scope beyond traditional superhero narratives. The cast’s diversity and the original characters crafted for this film indicate an ambitious attempt to deepen Gotham’s lore and emotional stakes. Fans and critics alike will be watching closely as this film may set the tone for future Batman-related projects under James Gunn’s guidance.
