Hold onto your seats, Marvel fans, because whispers of Oscar Isaac reprising his role as Moon Knight in the upcoming blockbuster Avengers: Doomsday have started to swirl. Surprising, right? But there's a fresh twist that's lending some credibility to this exciting speculation.
Over the weekend, fans were taken aback when Star Wars Celebration's official social media announced that Isaac would not be attending the much-anticipated event in Japan this year. The reason? Changes in his production schedule. This announcement had initially sparked hopes of seeing Isaac reprise his role as Poe Dameron in the Star Wars universe, especially after Daisy Ridley's appearance at Star Wars Celebration 2023 to announce her return in a new film. However, the shift in Isaac's schedule has now turned fans' attention towards the Marvel Cinematic Universe.
Although details of Isaac's new commitments remain under wraps, the fact that Avengers: Doomsday is currently filming in London has not gone unnoticed. Social media is buzzing with speculation that Isaac could be gearing up to don the Moon Knight suit once again.

While this is still just a theory, it's worth noting that Marvel loves to keep fans on their toes. Oscar Isaac was not listed among the cast members announced for Doomsday, but Marvel Studios producer Kevin Feige hinted at more surprises during a CinemaCon video call, stating, "We revealed many, not all." This leaves the door open for potential additions to the cast, including Isaac.
Isaac's portrayal of Moon Knight in the 2022 series was a hit, but no sequel has been officially announced yet. Avengers: Doomsday is slated to premiere on May 1, 2026, promising a grand ensemble of returning heroes and new faces as showcased in the epic livestream.
Meanwhile, the MCU community is abuzz with another intriguing detail: Robert Downey Jr. recently sent out a Doctor Doom-themed invitation for his 60th birthday party, further fueling speculation and excitement around the upcoming film.
AnswerSee ResultsLast month's Avengers: Doomsday cast reveal was a treasure trove of veteran X-Men actors. Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden are all confirmed to appear, signaling a major role for the X-Men in the film. Grammer, who played Beast in the Fox X-Men franchise, made his MCU debut in The Marvels' post-credits scene. Stewart, known for his role as Charles Xavier/Professor X, had a cameo in the MCU through Doctor Strange in the Multiverse of Madness as part of the Illuminati. Meanwhile, McKellen (Magneto), Cumming (Nightcrawler), Romijn (Mystique), and Marsden (Cyclops) have yet to make their MCU appearances. This lineup raises a tantalizing question: could Avengers: Doomsday be setting the stage for an epic Avengers vs. X-Men showdown?
