James Gunn has directly addressed the recent wave of James Gunn Superman casting rumors, clarifying speculation about the next DC Universe film, Man of Tomorrow. As DC Studios progresses with their plans following the 2025 Superman movie, questions have arisen over potential characters that might appear in the cinematic sequel, with particular focus on Wonder Woman’s supporting cast.
Rumors Swirl Around Steve Trevor’s Potential Appearance
The latest talk began after a Threads user suggested that Steve Trevor—a prominent figure in Wonder Woman lore—might be cast for Man of Tomorrow. The speculation quickly gained attention within the DC fan community. Steve Trevor was previously brought to life in the DCEU by Chris Pine, making notable appearances in both Wonder Woman and Wonder Woman 1984.

James Gunn’s prompt and clear response to these rumors brought them to a halt, indicating that casting routines involving Steve Trevor are not currently underway for Man of Tomorrow.
Main Villain and Returning Characters in Man of Tomorrow
Instead of focusing on Steve Trevor, the 2027 film is reported to center on Brainiac, introducing the villain to the big screen for the first time. Man of Tomorrow will bring together David Corenswet as Superman and Nicholas Hoult as Lex Luthor, in a story that puts these key characters in an uneasy alliance. Gunn stated,
it’s a story about Lex Luthor and Superman having to work together to a certain degree against a much, much bigger threat. It’s more complicated than that, but that’s a big part of it. It’s as much a Lex movie as it is a Superman movie.
– James Gunn, Director.
Rachel Brosnahan returns as Lois Lane, and Frank Grillo is back as Rick Flag Sr., with speculation pointing toward other character reprisals from the 2025 Superman movie. Principal photography is expected to commence in April 2026, as Gunn both scripts and directs the highly anticipated entry for DC Studios.
The Future of Wonder Woman and Steve Trevor in the DCU
While Steve Trevor will not be featured in Man of Tomorrow, DC Studios is actively developing a new Wonder Woman film. The project’s screenplay is being written by Supergirl screenwriter Ana Nogueira, though it currently lacks both a director and a release date. Specific plot elements for the Wonder Woman reboot remain under wraps, but there is still a chance that Steve Trevor could make his DCU return in this upcoming project, providing opportunities for future audience engagement with the character.
Man of Tomorrow is slated to hit theaters on July 9, 2027, as anticipation builds for the next chapter in the Man of Steel’s ongoing journey across the DC Universe, with the James Gunn Superman casting rumors now firmly put to rest.
