James Gunn Confirms He’s ‘Already’ Writing His Next Film Ahead of ‘Superman: Man of Tomorrow’

James Gunn’s off‑hand reply on Threads – “Already in it. I had to do something while I was waiting for the assembly!!” – may sound like a flippant fan‑service moment, but it reveals a calculated maneuver amid a turbulent period for DC Studios.

The first concrete sign that the sequel “Superman: Man of Tomorrow” is moving forward came when Gunn answered a fan’s query about the assembly cut with a terse “Yep!” on Threads. The milestone matters because it confirms that the merger’s leadership shake‑up – notably the exits of co‑CEOs Michael De Luca and Pamela Abdy – has not derailed Gunn’s production pipeline.

Gunn’s quick pivot to “already writing” his next feature signals more than personal productivity. Since taking the reins of DC Studios with Peter Safran in 2022, he has overseen a reboot that began with David Corenswet’s 2025 “Superman” debut, followed by the mis‑firing “Supergirl.” The sequel will pair Superman with Lex Luthor (Nicholas Hoult) against Brainiac, while re‑uniting Rachel Brosnahan, Skyler Gisondo, and newcomers like Aaron Pierre. By starting the next script while awaiting the assembly cut, Gunn is likely cementing narrative continuity across the franchise, ensuring that the story beats of “Man of Tomorrow” dovetail with the broader DCU roadmap that now includes an eight‑episode true‑crime series “The People V Gorilla Grodd.” That series, confirmed by Gunn on Threads as post‑Man of Tomorrow in the timeline, will expand the DCU’s genre palette and test the flexibility of its shared continuity.

The corporate backdrop adds another layer. The $111 billion Paramount‑Skydance acquisition of Warner Bros. Discovery, announced the same week, positions the merged entity to report to Paramount Pictures co‑chairs Dana Goldberg and Josh Greenstein. While Gunn and Safran are assured of their roles, the deal’s long‑term effect on DC’s creative autonomy remains opaque.

What remains unclear is the exact nature of the next film. No title, genre, or release window has been disclosed, and even the rumored 10‑year DCU plan that David Ellison supposedly signed off on on set has not been formally confirmed. For fans, the key question is whether Gunn will continue the Superman‑centric saga, branch into a different hero, or perhaps integrate the “Gorilla Grodd” narrative into the cinematic thread. Until the assembly cut translates into a final edit and box‑office numbers arrive, the next chapter resides in speculation – but Gunn’s already‑in‑it posture tells us the creative engine is far from stalling.

In sum, Gunn’s comment is a signal to both studios and audiences: the DCU’s story is being actively plotted even as corporate tides shift, and the assembly‑cut milestone serves as a concrete checkpoint that the upcoming Superman sequel remains on track.
