Mike Flanagan has long made horror about what hides beneath the surface, from The Haunting of Hill House to Midnight Mass and The Life of Chuck. That made his long-gestating Clayface especially intriguing, since the DC villain offered Flanagan another way to turn transformation, identity and monstrosity into character drama. Now, however, Flanagan is drawing a clear line between the Clayface he wrote and the movie James Watkins is bringing to theaters.

The distinction matters because Flanagan was once attached to Clayface as the filmmaker behind the project, making his name synonymous with DC's first feature centered on the shape-shifting villain. But after creative changes, the movie moved into Watkins' hands, with Hossein Amini also coming aboard for the screenplay.

Flanagan is now opening up about just how far removed he is from the finished film.

For a filmmaker whose work often involves taking familiar horror mythology and digging into the emotional machinery underneath it, Clayface was an unusually open canvas. Mike Flanagan told ComicBookMovie that the character had never previously headlined a live-action feature, which gave him room to build his own interpretation. But that interpretation is not the one he expects audiences to see.      

“I wrote a script I loved and I turned it in and then that’s the last. I haven’t even seen it. I’m excited to see it and see what James did with it,” he said, speaking to CBM.  

Flanagan made those comments to Comic Book Movie while discussing his upcoming Carrie series. That is an important distinction given how much the project changed hands. James Watkins, whose credits include Eden Lake and the 2024 Speak No Evil remake, now directs, while the official film site credits the screenplay to Watkins, Flanagan and Amini, with story by Flanagan. Clayface stars Tom Rhys Harries as Matt Hagen and is scheduled to hit theaters on October 23, 2026.

For fans who have followed Flanagan from Oculus and Hush through Doctor Sleep, Hill House and The Fall of the House of Usher, his fingerprints usually signal a particular kind of horror: intimate, character-driven and interested in the wound beneath the monster. His own career history makes the separation around Clayface all the more notable. 

This particular timing makes Mike Flanagan's Clayface clarification especially interesting. Flanagan is currently returning to Stephen King territory with Carrie, another project built around a character whose supernatural abilities are inseparable from isolation, humiliation and identity. The eight-episode Prime Video series premieres October 7, with Summer H. Howell playing Carrie White. 

Early reviews have given Carrie an 84% Rotten Tomatoes score from 39 reviews as of October 1, making it the lowest-rated Flanagan television series on the platform by that particular measure. That number comes with an important catch: the response remains broadly positive, and critics have highlighted the series' expansion of Stephen King's story, including its focus on cyberbullying and social-media-driven cruelty. 

So while Flanagan's Clayface connection remains firmly embedded in the movie's credits, Carrie is the project where his current creative voice can actually be seen on screen. Clayface, meanwhile, now belongs to James Watkins, and Flanagan himself seems content to watch the transformation from the audience.
