A new Clayface TV spot is running ahead of the film’s October 23, 2026 release, and it is the first piece of marketing to show Matt Hagen losing the argument with his own body in a room full of people.
The spot runs about thirty seconds. It puts Tom Rhys Harries in a club, opposite a woman whose reaction does most of the work, and lets his features slide out of position while he is still trying to hold a conversation. The shot that lands is a hand that appears to boil, mutating outward from the fingers. The debt to the hospital sequence in Akira is not subtle, and it is not meant to be.
What the spot does not show is the finished monster. That is a decision, not an oversight.
Why the Finished Monster Is Staying Off the Poster
Director James Watkins told Empire that Clayface’s full form will not appear in any promotional material before release, and gave the oldest reason in the genre for it: you do not want to show the shark. Harries, speaking to the same magazine, described the final design as “f—ing sick” and declined to go further.

That is a rarer piece of discipline than it sounds. A studio sitting on its creature design through the entire campaign of a wide October release is choosing to sell the film on dread instead of on a merchandisable silhouette. It also explains the shape of the marketing so far: hands, faces, skin, the slow parts. The spot sells the symptom and withholds the diagnosis.
Worth noting where this actually came from. Neither quote arrived in a press release. Both come out of an Empire feature, and the spot itself has been running on the film’s social channels rather than landing as a formal trailer drop.
The Horror Resume Behind the Camera
Watkins is the reason to take this seriously. Eden Lake remains one of the meaner British films of its decade. The Woman in Black showed he could build dread out of an empty house and bad weather. Speak No Evil ran on the specific discomfort of people too polite to leave a situation that is obviously going wrong. None of that is superhero grammar, and all of it is useful for a film about a man whose body stops taking instructions.

The screenplay is by Mike Flanagan and Hossein Amini, from a story by Flanagan. Naomi Ackie plays the scientist whose treatment sets the change in motion, and Max Minghella, David Dencik and Eddie Marsan fill out the cast. Matt Reeves, Lynn Harris, James Gunn and Peter Safran produce.
The film carries an R rating, the first in James Gunn’s DCU, for strong bloody violence, gore, language, some nudity and brief drug use. The first full trailer landed in July and set the register the TV spot is now working in.
What Nobody Has Confirmed Yet

Whether the final transformation is practical, digital or some negotiated settlement between the two has not been stated by anyone at DC Studios, and the withholding strategy means it probably will not be before October 23. For a film whose entire pitch is a body coming apart, that is the one technical question worth asking, and it is the one the campaign is most carefully not answering.
Clayface opens in theaters on October 23, 2026, near the back of an October that is already crowded.
