James Gunn already writing film after Man of Tomorrow

James Gunn has started writing his next film before his current one has reached cinemas.

The co-chief executive of DC Studios said he is "already in it" when a fan asked on Threads if he was ready to write the project that will follow Man of Tomorrow, according to Deadline. Gunn added that he began the script while waiting for the edit on his Superman sequel. That wait is short. Production wrapped in August.

"I had to do something while I was waiting for the assembly!!" Gunn wrote in reply to the fan, according to Deadline. The assembly is the first rough cut, pieced together before the director tightens scenes and sound. Gunn did not name the new project.

Man of Tomorrow is the sequel to 2025's Superman, which Gunn directed, and the fourth film in the new DCU, the connected series of films and shows he is overseeing with Peter Safran, according to Deadline. It is set to premiere in theatres on July 9, 2027. Gunn is writing and directing, according to Deadline.

David Corenswet returns as Clark, according to Deadline. Aaron Pierre has joined the cast, according to Deadline. Adria Arjona plays Maxima, according to Deadline, with Matthew Lillard also in the line-up, according to Variety.

The sequel sits inside a busy slate. DC Studios has released Superman and Supergirl, according to Deadline. Clayface is due on Oct. 23. The Batman: Part II is now in production for Feb. 18, 2028.

Gunn and Safran took charge of DC Studios after the Warner Bros. Discovery merger in 2022, according to Deadline. They will stay on after David Ellison invited them to continue through the Paramount-Warner Bros. Discovery merger. The combined company has been renamed Skydance, with the Paramount and Warner Bros. film units to report to Paramount Pictures co-chairs Dana Goldberg and Josh Greenstein.

What makes this stand out is the timing. Directors often pause between a wrap and an edit. Gunn is using the gap to get the next story on the page.
