James Gunn is Writing His Next Project While "Man of Tomorrow" Sequel is in Post-Production

DC Studios co-CEO James Gunn has confirmed he has already begun writing his next film project, even as the assembly cut of his upcoming DC Universe movie, "Man of Tomorrow," is being finalized. Gunn revealed the news on social media platform Threads in response to a fan's question.

Gunn, who also directed the first "Superman" film, stated that the writing commenced because he "had to do something while I was waiting for the assembly." The assembly cut is understood to be the initial edit of the film. He had previously announced that the assembly cut for "Man of Tomorrow" was completed, suggesting his focus will shift back to post-production on that film.

While Gunn did not disclose any details about the new project, it is widely expected to be another DC Studios production given his exclusive deal with Warner Bros. Discovery. Many upcoming DC projects have confirmed writers and directors, leaving the specific nature of Gunn's next endeavor a subject of speculation. Possibilities range from a follow-up "Superman" film to a potential "Justice League" movie.

In related news, Gunn also addressed fan speculation regarding casting in "Man of Tomorrow." Actor Frank Grillo had shared a fan-made poster depicting Adria Arjona as Wonder Woman. Gunn clarified on Threads that Grillo is unaware of Arjona's actual role in the DCU and that any potential cameo in "Man of Tomorrow" would be minor, emphasizing that fans were overemphasizing the matter. He also recently debunked rumors that Matthew Lillard would be portraying The Flash in the new DC Universe.
