Warner Bros. announced Saturday that Clayface, the DC Studios body-horror film directed by Mike Flanagan and starring Tom Rhys Harries as the shape-shifting Matt Hagen, will move from its original March 2027 theatrical date to October 2027, capitalising on Halloween-season positioning after the debut trailer generated unexpected online momentum.

The trailer, which dropped Thursday to coincide with coverage from entertainment press, had accumulated more than 10 million views across YouTube and social platforms by Saturday morning, with horror and comic-book audiences responding strongly to the film's practical-effects-heavy approach to Hagen's transformation sequences. Industry tracking sites noted search interest in Clayface spiked to levels not seen for a DC property since the early Joker marketing cycle.

DC Studios co-CEO James Gunn addressed the release date shift in a brief post on social media Saturday, framing the move as a strategic opportunity rather than a production concern. 'Clayface belongs in October,' Gunn wrote, adding that test screening scores had exceeded internal benchmarks. Flanagan, known for Netflix horror hits including The Haunting of Hill House and Midnight Mass, is widely credited with bringing a tone to the project that distinguishes it from conventional superhero fare.

Tom Rhys Harries, the Welsh actor best known for his role in White Collar Crime and the ITV series Trigger Point, has drawn particular praise in early reactions for the physical and psychological vulnerability he brings to Hagen, a struggling actor who gains monstrous abilities at catastrophic personal cost. Several critics who saw early footage described the film as closer in spirit to The Fly than to a traditional DC ensemble picture.

The repositioning to October puts Clayface in a corridor Warner Bros. has used successfully for horror-adjacent releases, and analysts at tracking firm PostTrak noted the move likely signals strong internal confidence in the cut. A formal marketing campaign, including IMAX poster reveals and a possible appearance at San Diego Comic-Con in July, is expected to follow in the coming weeks.
