James Gunn starts writing next film ahead of Superman sequel

Filmmaker James Gunn has already started writing his next film as work continues on the upcoming superhero movie ‘Superman: Man of Tomorrow’.

Gunn confirmed the update in response to a comment on Threads asking whether he was ready to begin writing his next film.

“Already in it. I had to do something while I was waiting for the assembly!” Gunn replied, also confirming that the assembly cut of ‘Superman: Man of Tomorrow’ is complete.

Gunn had earlier announced in August that filming for the superhero sequel had wrapped.

A sequel to the 2025 film ‘Superman’, the upcoming movie will once again feature David Corenswet as Superman. The film is scheduled to release in theatres on July 9, 2027.

‘Superman: Man of Tomorrow’ will follow Superman as he joins forces with his adversary Lex Luthor, played by Nicholas Hoult, to face a greater threat in the form of the superintelligent villain Brainiac, portrayed by Lars Eidinger.

Rachel Brosnahan will return as Lois Lane, alongside Skyler Gisondo as Jimmy Olsen, Sara Sampaio as Eve Teschmacher, Isabela Merced as Hawkgirl, Nathan Fillion as Guy Gardner and Edi Gathegi as Mister Terrific.

Milly Alcock, who appeared as Superman’s cousin Kara Zor-El, will also return for the sequel. The film will additionally introduce Aaron Pierre as John Stewart, a character who will debut in the HBO Max series ‘Lanterns’.

Gunn has been leading DC Studios alongside Peter Safran since 2022.

Speaking to Variety earlier, Gunn praised Safran for complementing his working style and helping keep DC Studios aligned across its different departments. He also said they share a strong connection to the characters and understand the responsibility of shaping how audiences see them.

‘Superman: Man of Tomorrow’ is set to arrive in theatres on July 9, 2027.
