The future of Superman 3 may already be taking shape, as new updates from Superman: Man of Tomorrow suggest that James Gunn is building a long-term Superman storyline within the DC Universe.
Although DC Studios has not officially announced Superman 3, recent casting developments strongly suggest that the studio is already laying the groundwork. As a result, fans may soon see a broader Superman saga unfold across multiple films.
Superman 3 Setup Begins During Man of Tomorrow Production
According to recent reports, Superman: Man of Tomorrow is preparing to begin production this month in Atlanta. At the same time, James Gunn is directing the film from his own script, which signals a more unified creative vision for the DCU.
This development is particularly important because Gunn has repeatedly emphasized long-term storytelling across multiple projects. Therefore, Superman: Man of Tomorrow may not just be a standalone film, but rather a major stepping stone toward Superman 3.
Maxima’s Role Could Be Crucial for Superman 3
Industry insider Jeff Sneider confirmed that the casting team is genuinely casting Maxima and not using a placeholder name.
“The character of Maxima — no tricks.”
Furthermore, Jeff Sneider revealed that Maxima will likely have a smaller role in Superman: Man of Tomorrow before becoming more important in future DCU projects.
“Apparently, the character has a small role in this film before becoming a bigger character in the inevitable third Superman movie.”
Because of this, Superman 3 may feature Maxima as a central figure. In DC Comics, Maxima stands out for her immense strength, advanced alien technology, and a complex relationship with Superman that shifts between alliance and conflict depending on her goals and motivations. Therefore, her introduction could expand the cosmic scale of the DCU.
James Gunn’s Long-Term Superman 3 Vision
Although Superman 3 has not yet been officially confirmed, James Gunn has already hinted at a long-term Superman storyline.
He previously explained:
“I am like thinking ‘what is the long-term story I’m telling here? What is the story that I’m gonna tell about Superman over four movies?’”
This statement suggests that Gunn is planning a multi-film Superman arc rather than standalone installments. Consequently, Superman 3 could serve as a major turning point in the larger DCU narrative.
Additionally, Gunn’s involvement as both writer and director helps ensure narrative continuity. As a result, the upcoming films may feel more connected than previous DC movie franchises.
DCU’s Expanding Superman Saga
The developing DCU storyline is expected to unfold across multiple interconnected films. It will begin with Superman, followed by Superman: Man of Tomorrow, which is expected to expand the character’s journey. After that, Supergirl is likely to further build the universe, potentially leading into a Superman 3 that could serve as a major continuation of the broader DCU storyline.
Furthermore, DC Studios appears to be positioning Superman as the central figure of Chapter 1. Therefore, each project may contribute to a larger narrative arc that ultimately leads into Superman 3.
However, the continuation of this storyline will likely depend on the box office success of upcoming DCU films. If the early entries perform well, Superman 3 could quickly move into active development.
Four Actresses Reportedly Competing for Maxima
Meanwhile, reports suggest that four actresses are currently in contention for the role of Maxima after screen tests in Atlanta:
- Adria Arjona
- Eva De Dominici
- Sydney Chandler
- Grace Van Patten
Each of these actresses brings a unique style and screen presence. Therefore, whoever lands the role may become a key player in future DCU films, including Superman 3.
Additionally, the fact that multiple actresses are screen testing suggests that DC Studios is taking the casting very seriously, which further highlights Maxima’s importance.
Superman: Man of Tomorrow is scheduled to release on July 9, 2027, as part of DCU Chapter 1: Gods & Monsters.
Because of this, Superman 3 could serve as a major continuation of Chapter 1’s storyline. Additionally, the introduction of cosmic characters like Maxima suggests that the DCU may expand beyond Earth-based stories.
Furthermore, this approach aligns with James Gunn’s broader plan to introduce diverse characters and settings across the DC Universe.
These developments suggest that Superman 3 is quietly being prepared behind the scenes. While the film remains unconfirmed, the introduction of Maxima and long-term planning strongly indicate that the third installment is part of the DCU roadmap.
If upcoming DCU films perform well, Superman 3 may officially move forward sooner than expected. Until then, Superman: Man of Tomorrow will likely play a crucial role in shaping the future of Superman in the DC Universe.
