As DC Studios co-head James Gunn puts the finishing touches on the upcoming superhero blockbuster Man of Tomorrow, the prolific filmmaker and executive is already looking ahead to his next creative endeavor. While managing the sprawling DC Universe (DCU) blueprint and overseeing post-production on the highly anticipated sequel to 2025’s Superman, Gunn revealed to fans that he has officially begun writing an entirely new, currently undisclosed project.
The update emerged directly from Gunn via Threads, the director’s preferred social media platform for engaging with comic book enthusiasts and industry observers alike. When a curious follower inquired about his current creative focus, Gunn lightheartedly explained that he initiated the new writing venture simply because he "had to do something while I was waiting for the assembly!"
The comment referred to the recently completed assembly cut of Man of Tomorrow, which represents the foundational rough edit of a feature film where all scenes are assembled in script order before the rigorous fine-tuning, pacing adjustments, and visual effects integration begin. Over the weekend, Gunn formally announced that this initial assembly milestone for Man of Tomorrow had been achieved. Because the production schedule for the upcoming DC film now shifts heavily into post-production and polishing, industry watchers note that Gunn’s mysterious new writing assignment will likely take a temporary backseat as he oversees the final stages of the Superman sequel, which is slated to arrive in theaters next year.
True to form, Gunn kept all major details regarding the secret project tightly under wraps, leaving fans and entertainment journalists to speculate on what might occupy the director’s attention next. Given Gunn’s overarching exclusive creative partnership with Warner Bros. Discovery—which faces upcoming structural evolution following planned corporate mergers—it remains safe to assume that his next endeavor will firmly anchor itself within the interconnected DCU slate.
While the broader DC film and television calendar already features a wide array of announced projects, the vast majority of those titles have already assigned their respective writers and directors, leaving Gunn out of the day-to-day scripting duties for those specific films. This leaves room for intense speculation over whether Gunn could be plotting a potential third cinematic installment in his revived Superman saga, or perhaps finally tackling a definitive, ensemble-driven Justice League feature for the new era of the franchise.
Gunn Continues to Shoot Down Wonder Woman Rumors
Amid the excitement surrounding his future writing endeavors, Gunn also found himself actively dampening another wave of fan-fueled speculation, this time ignited by a fellow DCU collaborator. Frank Grillo, a prominent actor within the expanding cinematic universe, recently reposted a fan-made promotional poster on social media depicting actress Adria Arjona in the iconic armor of Wonder Woman.
The image immediately stoked persistent fan theories circulating online, which have heavily pointed toward Arjona stepping into the role of the legendary Amazonian warrior within the new DC continuity, despite a complete lack of official confirmation from studio executives. Recognizing that the rumor mill was spiraling out of control, Gunn stepped in directly on social media to address the mounting expectations and clarify the situation for fans.
"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, addressing the speculation head-on. "People have been making way too much of this."
The incident highlights the intense scrutiny and enthusiastic sleuthing directed at the DCU’s casting announcements. While a handful of established performers are confirmed to be reprising familiar comic book roles or transitioning into new interpretations within Gunn’s revived framework, it is the mysterious newcomer castings that continue to capture the highest level of public curiosity.
Arjona’s exact character in the upcoming film and wider universe remains a closely guarded secret, serving as a primary focal point for fan theories across social media platforms. However, she is not the only actor to find herself at the center of unverified casting rumors. Just days prior to Grillo’s social media post, Gunn was forced to publicly debunk a viral rumor suggesting that actor Matthew Lillard was slated to play the Flash in the DCU.
As Man of Tomorrow moves steadily through its post-production phase toward its scheduled theatrical release next year, Gunn’s dual role as a hands-on filmmaker and studio architect continues to generate immense public interest. Whether his newly initiated writing project turns out to be a surprise expansion of the current slate or a foundational building block for later chapters of the DCU, fans will have to wait for official announcements from DC Studios to learn what the filmmaker has in store next.
