James Gunn Confirms He’s ‘Already’ Writing His Next Project

James Gunn announced on Threads that he is actively working on writing his next film ahead of the release of “Superman: Man of Tomorrow,” due in theaters July 9, 2027.

Milly Alcock, who cameoed as Superman’s cousin Kara Zor-El, returns for “Man of Tomorrow” after headlining this summer’s DC tentpole, “Supergirl.” The sequel will also introduce Aaron Pierre to the big screen as John Stewart, who is debuting in the HBO Max series “Lanterns.”
