James Gunn has responded to recent speculation regarding new characters appearing in the upcoming Superman film, following comments made earlier by Black Adam actor Pierce Brosnan. The director’s remarks have clarified circulating rumors about Doctor Fate, while at the same time generating interest around the possible introduction of the Wonder Twins.
Pierce Brosnan’s Statements Stir Talk of Doctor Fate Appearance
Earlier in the day, Pierce Brosnan, known for his role in Black Adam and as James Bond, appeared to suggest during an interview that there were plans involving Doctor Fate and the next Superman film. Brosnan did not specifically reference returning to the character, but his remarks sparked speculation among fans that Doctor Fate could debut in the DCU’s upcoming Man of Tomorrow.
This idea gained traction because James Gunn’s Superman is set to feature several new characters, and it would not seem out of character for a figure like Doctor Fate to make an appearance. However, considering that a different Superman film had previously been discussed during the early planning phase—before the DC Extended Universe was rebooted as the DC Universe—it seems plausible Brosnan’s reference was to a now-abandoned project, rather than the current direction.
James Gunn Responds to the Doctor Fate Inquiry
James Gunn was questioned on social media platform Threads about Brosnan’s hints. Gunn directly addressed the rumors, stating:
“I’ve never heard a Dr Fate rumor”
— James Gunn, Director
This brief response from Gunn appears to end speculation regarding Doctor Fate’s inclusion in Man of Tomorrow.
Wonder Twins Speculation Grows from Gunn’s Social Media Activity
Although James Gunn quieted rumors about Doctor Fate, he has also inadvertently sparked talk about the Wonder Twins by posting Alex Ross artwork featuring Jayna, Zan, and their alien companion Gleek. Gunn is known for frequently sharing images of DC characters and artwork without prior context, often leading to intense fan speculation.
It is worth recalling that a Wonder Twins movie, with KJ Apa and Isabel May set to star as the sibling heroes, was once rumored for development in 2023. That film, along with its notable casting, was halted before DC Studios took its current form, leaving the concept of a Wonder Twins appearance open-ended. Gunn’s recent online activity has revived curiosity regarding their future in the franchise.
Current Known Details and Ongoing Casting for Man of Tomorrow
What is confirmed about Man of Tomorrow is its focus on Superman, portrayed by David Corenswet, and Lex Luthor, played by Nicholas Hoult, as they confront the villainous Brainiac. Alongside these central figures, rumors suggest appearances by characters such as Supergirl, Lobo, and potential cameos from DC’s Peacemaker series.
There are also unsubstantiated reports that a reimagined Wonder Woman may enter the DCU through this film, supported by recent casting information hinting at Diana’s possible debut. Meanwhile, the role of Brainiac remains in the casting phase. Claes Bang, known for his performances in Dracula and Bad Sisters, is reported to be among the actors who have auditioned, though Gunn and DC Studios have not confirmed any names at this time.
Looking Ahead to the Superman Reboot and the DCU’s Future
Man of Tomorrow is scheduled for release on July 9, 2027, with production expected to begin during the following summer. As casting continues and official details remain limited, speculation around potential heroes—such as the Wonder Twins and a new version of Wonder Woman—will likely persist. The DCU’s renewal under James Gunn has sparked anticipation among fans and raised questions about which characters will join Superman, Lex Luthor, and Brainiac in shaping the next chapter of DC’s cinematic universe.
