Director James Gunn has confirmed he is already working on a new writing project, even as post-production continues on Man of Tomorrow, the highly anticipated sequel to 2025’s Superman. Revealing the news over the weekend in response to a fan inquiry on Threads, Gunn disclosed that he had begun drafting his next film simply because “had to do something while I was waiting for the assembly.” The director noted that the assembly cut of Man of Tomorrow—a rough first draft of the movie’s edit—was completed this past weekend, meaning post-production demands will likely pull him away from whatever new project he has just started.
Gunn did not reveal any specifics about his upcoming endeavor, leaving fans and industry observers to speculate. Given his exclusive deal with Warner Bros. Discovery—which is soon to become Skydance following its merger with Paramount—it would be reasonable to assume the next project will land within the DC universe. However, most titles already on the studio’s schedule have confirmed writers and directors attached who are not Gunn himself.
A Mysterious Next Chapter in the DC Universe
While details remain tightly under wraps, speculation has ranged from a potential third Superman film to hopes for a true Justice League feature. The director maintains tight control over what information he releases about his slate of projects, and this latest revelation follows that familiar pattern. Whatever Gunn is writing will likely be officially announced in due course, but for now it remains shrouded in mystery.

Gunn Reins In Wonder Woman Speculation
Beyond confirming his new writing venture, Gunn spent time quelling rumors sparked by one of Man of Tomorrow’s cast members. Actor Frank Grillo reposted a fan-made poster depicting Adria Arjona as Wonder Woman, an idea that has become the prevailing theory among fans despite lacking any official confirmation. Gunn, who has previously tempered expectations on this exact topic, seized the moment to address supporters once more.
“Frank doesn’t know who Adria is playing in the DCU and whether or not she has any sort of incredibly small cameo in [Man of Tomorrow] or not,” Gunn wrote. “People have been making way too much of this.”
The DC universe’s newcomers continue to generate as much curiosity as its returning veterans. Alongside Arjona, whose role remains unconfirmed, Matthew Lillard has also become the subject of widespread fan speculation. Just days earlier, Gunn felt compelled to shut down a circulating rumor that Lillard would portray the Flash in the DCU.
Looking Ahead
With Man of Tomorrow still slated for release next year, post-production will consume much of Gunn’s attention as the film moves toward its final form. Until then, his newly embarked writing project and any hints about its subject matter remain unannounced. Fans hoping to learn more can expect further updates from Gunn through his usual channels once he has room in his schedule.
