DC Studios has greenlit a feature film centered around the shape-shifting villain Clayface, with the script being written by Mike Flanagan. Filming is set to begin in early 2025, and Flanagan has expressed interest in working on a standalone Clayface movie for a while. With Alan Tudyk portraying a version of Clayface in the Creature Commandos series, there could be multiple interpretations of the character on screens in the coming years. Flanagan's horror/thriller approach to the character promises a unique and potentially terrifying take on the iconic Batman villain.
