James Gunn Explains Why the Clayface Movie Had to Be a Part of the DCU and Not Matt Reeves' The Batman Epic Crime Saga

DCU co-heads James Gunn and Peter Safran have confirmed the upcoming Clayface film as a DCU canon entry, boasting an R-rating. This adaptation of the classic Batman villain, known for his shape-shifting clay-like body, will mark a significant departure from previous DC cinematic outings.

Basil Karlo, the original Clayface, debuted in Detective Comics #40 (1940). The film, slated for release on September 11, 2026, follows the successful HBO Max series, The Penguin, and its decision to focus on Clayface reportedly stems from that show's positive reception. Horror maestro Mike Flanagan penned the screenplay, with Lynn Harris producing alongside Matt Reeves, director of The Batman.

Gunn and Safran, speaking at a DC Studios presentation, emphasized Clayface's distinct place within the DCU, separate from Matt Reeves' The Batman universe. Safran clarified that Reeves' "Crime Saga," encompassing the Batman trilogy and The Penguin, remains under DC Studios but operates independently.

The choice to include Clayface in the main DCU was deliberate. Gunn highlighted that Clayface's origin story, a key component of the film, complements their vision for the broader cinematic universe. He further explained that the character's nature wouldn't have fit the grounded realism of Reeves' films.

Negotiations with James Watkins (Speak No Evil) to direct are reportedly nearing completion, with filming commencing this summer. Safran described the project as an "experimental" and "indie-style chiller," a body horror film offering a compelling origin story for a lesser-known but equally terrifying villain. Gunn described it as "pure f***ing horror," emphasizing its realistic, psychological, and visceral nature.

The R-rating was confirmed, reflecting the film's intended intensity. Gunn expressed his enthusiasm for the project, stating that if presented with the script five years prior, they would have eagerly produced it regardless of its DCU connection. The film's placement within the DCU is considered a bonus.
