Back in 2021, filmmaker Mike Flanagan let it be known on social media that he was interested in making a “standalone horror/thriller/tragedy” movie that would center on the DC Comics character Clayface, who is usually presented as a villain in the pages of Batman comic books. A while after that, he confirmed that he had met with veteran DC movie producer Jon Berg to pitch a “horror-leaning” take on Clayface, as well as ideas for the DC properties Scarecrow, Justice League Dark, and Constantine. The meeting “kind of went nowhere.” But then, in March of 2023, Deadline broke the news that Flanagan had scheduled another Clayface pitch meeting, this time with DC Studios bosses James Gunn and Peter Safran. And at the end of last year, it was announced that Flanagan is officially writing a Clayface movie that will be part of the DC Universe film franchise that’s being overseen by Gunn and Safran.
