Hold onto your seats, Marvel fans! There's buzz that Oscar Isaac might be reprising his role as Moon Knight, and not just anywhere but in the highly anticipated Avengers: Doomsday. Surprising? Absolutely, but there's a recent twist that's fueling this exciting speculation.
Over the weekend, Star Wars Celebration announced that Isaac would no longer be attending the event in Japan due to a shift in his production schedule. This news came as a shock, especially since Isaac's appearance was announced back in February, stirring up whispers of Poe Dameron's potential return to the Star Wars universe. Following Daisy Ridley's announcement at Star Wars Celebration 2023 about her role in a new film, fans were eager to see if Isaac had similar plans.
While the specifics of Isaac's new production commitments remain under wraps, the fact that Avengers: Doomsday is currently filming in London has led fans to connect the dots and speculate about Moon Knight's involvement. Social media erupted with fans piecing together the clues:

It's important to note that this is still just a theory. Marvel is known for keeping secrets, and Isaac's name wasn't included in the initial Doomsday cast reveal. However, Marvel Studios producer Kevin Feige hinted at more surprises during a video call at CinemaCon, stating, "We revealed many, not all," leaving the door open for possibilities.
Isaac previously starred as Moon Knight in a six-episode series released in 2022, but no sequel has been announced yet. Avengers: Doomsday is slated to premiere on May 1, 2026, promising a lineup of returning heroes and new faces, as showcased in the epic livestream.
Meanwhile, MCU enthusiasts have also been intrigued by Robert Downey Jr.'s recent Doctor Doom-themed birthday invitation, adding another layer of mystery to the unfolding saga.

Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden are all confirmed to join the film, signaling a major X-Men presence. 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, briefly appeared in the MCU in Doctor Strange in the Multiverse of Madness as part of the Illuminati. McKellen, who portrayed Magneto, along with Cumming (Nightcrawler), Romijn (Mystique), and Marsden (Cyclops), have yet to make their MCU debut. This raises an intriguing question: is Avengers: Doomsday secretly an Avengers vs. X-Men movie?
