Oscar Isaac Exits Star Wars Event, MCU Fans Speculate Moon Knight in Avengers: Doomsday

Author:Kristen Update:May 06,2025

Rumors are swirling that Oscar Isaac might be reprising his role as Moon Knight in the much-anticipated film, *Avengers: Doomsday*. This speculation has gained traction following a surprising announcement from Star Wars Celebration's official social media, which stated that Isaac would not be attending the convention in Japan this year due to changes in his production schedule.

Back in February, Isaac's confirmed appearance at Star Wars Celebration had fans buzzing about the possibility of his return as Poe Dameron in the Star Wars universe. This excitement was fueled by Daisy Ridley's announcement at Star Wars Celebration 2023 that she would star in a new Star Wars film. With Isaac's withdrawal from the event, fans are now speculating that he might be gearing up to film scenes for *Avengers: Doomsday* in London, where the movie is currently in production.

Social media has been abuzz with fans connecting the dots:

While these rumors are exciting, it's important to note that they remain just that—rumors. Isaac was not included in the initial cast reveal for *Avengers: Doomsday*. However, Marvel Studios producer Kevin Feige hinted at more surprises, stating during a video call at CinemaCon that the livestream did not feature the entire cast: "We revealed many, not all," leaving room for speculation and hope among fans.

Isaac's portrayal of Moon Knight in the 2022 six-episode series was well-received, though no follow-up season has been announced. *Avengers: Doomsday* is slated for release on May 1, 2026, and promises to bring back a host of heroes and familiar faces as showcased in the epic livestream.

Meanwhile, MCU enthusiasts have also been intrigued by Robert Downey Jr.'s recent Doctor Doom-themed 60th birthday party invitation, adding another layer of mystery and excitement to the Marvel universe.

The cast reveal for *Avengers: Doomsday* last month was a significant event, particularly for fans of the X-Men franchise. Notable actors from the Fox X-Men series, including Kelsey Grammer (Beast), Patrick Stewart (Charles Xavier/Professor X), Ian McKellen (Magneto), Alan Cumming (Nightcrawler), Rebecca Romijn (Mystique), and James Marsden (Cyclops), are confirmed to appear in the film. This has led to speculation that *Avengers: Doomsday* might be setting up an epic clash between the Avengers and the X-Men.
