Rumors are swirling that Oscar Isaac could be reprising his role as Moon Knight in the highly anticipated Avengers: Doomsday. This speculation gained traction following a surprising announcement from Star Wars Celebration's official social media, which stated that Isaac would no longer be attending the event in Japan due to changes in his production schedule. Initially, fans were excited about Isaac's potential return to the Star Wars universe as Poe Dameron, especially after Daisy Ridley confirmed her role in a new Star Wars film at the 2023 celebration.
While the specifics of Isaac's scheduling changes remain undisclosed, the timing coincides with the ongoing production of Avengers: Doomsday in London. This has fueled speculation among fans that Isaac might be involved in the Marvel blockbuster. Social media platforms buzzed with reactions:

Despite the excitement, it's important to note that Isaac's name was not included in the initial cast reveal for Avengers: Doomsday. However, Marvel Studios producer Kevin Feige hinted at more surprises during a video call at CinemaCon, stating, “We revealed many, not all.” This leaves room for speculation and hope among fans.
Isaac's portrayal of Moon Knight in the six-episode series released in 2022 was well-received, but no follow-up has been announced yet. Avengers: Doomsday is slated to premiere on May 1, 2026, promising a star-studded lineup of returning heroes and new faces, as highlighted during the epic livestream.
In other MCU news, fans have been intrigued by Robert Downey Jr.'s recent Doctor Doom-themed birthday invitation, adding another layer of mystery to the unfolding Marvel narrative.
The Avengers: Doomsday cast reveal last month prominently featured veteran X-Men actors, including Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden. Their inclusion confirms a significant presence of the X-Men in the film. Grammer, who played Beast, made his MCU debut in The Marvels' post-credits scene. Stewart appeared as Charles Xavier in Doctor Strange in the Multiverse of Madness. Meanwhile, McKellen, Cumming, Romijn, and Marsden, known for their roles as Magneto, Nightcrawler, Mystique, and Cyclops respectively, have yet to make their MCU debut. This raises the intriguing possibility that Avengers: Doomsday might be setting the stage for an Avengers vs. X-Men showdown.
