Bradley Cooper’s secret role in Superman 2025 cast has been officially revealed, as James Gunn confirms that three members from Guardians of the Galaxy will appear in DC’s upcoming film, set for release on July 11. This announcement sheds light on the crossover between Gunn’s Marvel collaborations and the fresh lineup in the new DC universe, showcasing how established actors are taking on new parts in Superman’s story.
Guardians Stars Step Into Superman’s Fortress of Solitude
James Gunn, who serves as co-head of DC Studios and directs the much-anticipated Superman feature, has openly recruited several familiar faces from his work on Marvel projects. As speculation built around who might make a cameo in the new superhero film, Gunn confirmed that Bradley Cooper, Pom Klementieff, and Michael Rooker will take roles connected to Superman’s iconic Fortress of Solitude.
During a Superman press tour with Buzzfeed Australia, Gunn revealed that these three stars, known for their roles in Guardians of the Galaxy, will be involved in a key scene. The director stated,
“I will give you something that nobody knows. Pom Klementieff is one of the robots. In that same scene, it’s Bradley [Cooper], it’s also Pom, and Michael Rooker is another one of the robots. We’ve got two Guardians right there.” —James Gunn, Director
This confirmation aligns with months of hints from Gunn and rumors circulating about possible secret cast members. Sean Gunn, James Gunn’s brother, was already publicly attached as Maxwell Lord, adding to the significant Marvel-to-DC migration for the film. Now, Cooper, Klementieff, and Rooker join the growing list of Marvel actors stepping into new DC roles.
Klementieff, Rooker, and Cooper Assume Robotic Roles
Pom Klementieff had previously hinted that she was in talks with Gunn about entering the DC universe, and she will now officially contribute as a robot in Superman’s Fortress. Michael Rooker, who already voices Sam Fitzgibbon in Creature Commandos and makes an appearance in Peacemaker Season 2 as Red St. Wild, will voice another robot in this pivotal sequence, marking his third collaboration with Gunn within DC projects.
Bradley Cooper, best-known to Marvel audiences as the voice of Rocket Raccoon, has been widely rumored to take on the role of Jor-El, Superman’s Kryptonian father. Gunn’s recent confirmation places Cooper in the same Fortress of Solitude scene as Klementieff and Rooker, suggesting that he could be voicing yet another robot. However, speculation continues that he may still portray Jor-El, possibly making an appearance in this very scene, though no further details have been provided.
The Fortress Scene and Supporting Cast Spotlight
Recent previews of Superman, especially footage released in April, featured a sequence set in the Fortress of Solitude where the specialized robots tend to the injured Kal-El, portrayed by David Corenswet, utilizing yellow sun radiation for healing. This same sequence will feature the voice performances of Rooker alongside Alan Tudyk, who plays the main speaking part as Robot #4. With this, the film showcases not only established actors from previous superhero franchises but also new talent working together in the evolving DCU.
Superman stands as the first feature film installment under the new DC Studios universe, following the start of the franchise with Creature Commandos in December. Alongside the returning Marvel ensemble, the cast boasts talents such as Rachel Brosnahan, Nicholas Hoult, Isabela Merced, Nathan Fillion, and Edi Gathegi, demonstrating an intent to bridge storylines and create a dynamic blend of characters across genres.
More Marvel-to-DC Transitions and Future Prospects
The news of Cooper, Klementieff, and Rooker joining Superman comes as part of a larger trend, with several Marvel Cinematic Universe actors establishing a presence within the reimagined DC universe. James Gunn’s continued collaboration with his preferred cast members is creating increasing speculation about further crossovers.
During the Buzzfeed interview, Gunn was asked if other Guardians of the Galaxy alumni such as Dave Bautista or Zoe Saldaña would feature in Superman. He responded,
“We’re keeping them in the wing.” —James Gunn, Director
This suggests that, for now, these stars will not appear in Superman, but the possibility remains open for their involvement in future DC projects as the new universe expands.
Amid uncertainty regarding the Guardians’ fate in the Marvel Cinematic Universe—especially since Gunn’s departure—none of the actors have been included in the confirmed cast for the upcoming Avengers: Doomsday. However, the ending of Guardians of the Galaxy Vol. 3, with its note that The Legendary Star-Lord Will Return, points to continuing adventures for Chris Pratt’s character in Marvel, while other cast members may transition to new roles within the DC kingdom.
The strategic casting decisions for Superman not only build anticipation for the July release, but also reflect a shift in the superhero movie landscape, with talent crossing traditional studio lines. With Bradley Cooper’s secret role in Superman 2025 cast now public, fans of both Marvel and DC will be watching closely for more surprises and future collaborations as James Gunn continues to reshape the trajectory of the DC universe.
