Oscar Isaac Exits Star Wars Event, Sparks MCU Moon Knight Rumors

Authore: PeytonUpdate:May 23,2025

Get ready for a thrilling twist: Oscar Isaac could be reprising his role as Moon Knight in the upcoming blockbuster Avengers: Doomsday. This surprising news comes on the heels of a recent announcement that has set the fan community buzzing with excitement.

Over the weekend, fans were taken aback when Star Wars Celebration's official social media accounts announced that Isaac would not be attending the much-anticipated event in Japan this year. The reason cited was "changes in his production schedule." Back in February, Isaac's planned appearance at Star Wars Celebration had sparked rumors of a possible return to the Star Wars universe as Poe Dameron, especially after Daisy Ridley confirmed her involvement in a new Star Wars film at the 2023 celebration.

While the specifics of Isaac's altered schedule remain under wraps, the fact that Avengers: Doomsday is currently filming in London has led many to speculate that Moon Knight might be making a grand entrance into the Avengers saga. Social media erupted with fans connecting the dots:

Despite the excitement, it's important to remember that this is still just a theory. Oscar Isaac was not included in the initial cast announcement for Avengers: Doomsday. However, Marvel Studios producer Kevin Feige hinted at more surprises during a CinemaCon video call, stating, "We revealed many, not all." This leaves room for speculation and hope among fans.

Isaac previously starred as Moon Knight in a six-episode series released in 2022, but no follow-up has been officially announced yet. Avengers: Doomsday is slated to premiere on May 1, 2026, promising a spectacular lineup of returning heroes and new faces as revealed in a recent epic livestream.

In other Marvel news, fans are also buzzing about Robert Downey Jr.'s recent Doctor Doom-themed birthday party invitation, adding another layer of intrigue to the MCU's future.

Last month's Avengers: Doomsday cast reveal was packed with veteran X-Men actors, including Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden. This confirms a significant presence of the X-Men in the film. Grammer, known for his role as Beast in the Fox X-Men franchise, made his MCU debut in The Marvels' post-credits scene. Stewart, who portrayed Charles Xavier/Professor X, had a brief appearance in the MCU in 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 debuts. This raises the tantalizing question: is Avengers: Doomsday secretly an Avengers vs. X-Men movie?
