Hold onto your hats, Marvel fans—Oscar Isaac might be reprising his role as Moon Knight in the upcoming blockbuster, Avengers: Doomsday. Yes, you read that right! The buzz started when Star Wars Celebration announced that Isaac would miss his scheduled appearance at their Japan event due to a sudden change in his production schedule. Originally set to be a big draw at the convention, this news has fans speculating wildly about his next move.
Back in February, Isaac's planned attendance at Star Wars Celebration sparked rumors of his return as Poe Dameron. With Daisy Ridley already confirmed for a new Star Wars film at the 2023 event, the anticipation was palpable. However, the recent shift in Isaac's schedule has shifted the spotlight to Marvel's latest cinematic venture.
While no specifics were given about the nature of Isaac's scheduling changes, the fact that Avengers: Doomsday is currently filming in London has fueled the speculation fire. Social media erupted with fans connecting the dots:

Despite the excitement, it's important to remember this is still just a theory. Marvel loves to keep fans on their toes, and Isaac wasn't listed in the initial cast reveal for Doomsday. Yet, Kevin Feige, Marvel Studios' producer, hinted at surprises during a CinemaCon video call, stating, "We revealed many, not all." So, the dream of seeing Moon Knight in action with the Avengers isn't entirely out of reach.
Isaac's portrayal of Moon Knight in the 2022 six-episode series was a hit, but a second season has not yet been announced. Meanwhile, Avengers: Doomsday is slated to premiere on May 1, 2026, promising an epic ensemble of returning heroes and new faces, as showcased in the recent livestream.
In other Marvel news, fans are buzzing about Robert Downey Jr.'s intriguing Doctor Doom-themed birthday invitation, adding another layer of mystery and excitement to the MCU's future.
The Avengers: Doomsday cast reveal last month included a heavy dose of X-Men alumni, with actors like Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden set to appear. This has led to speculation that the film might secretly be an Avengers vs. X-Men showdown. Grammer's Beast made his MCU debut in The Marvels, while Stewart's Professor X appeared in Doctor Strange in the Multiverse of Madness. However, McKellen's Magneto, Cumming's Nightcrawler, Romijn's Mystique, and Marsden's Cyclops are yet to officially join the MCU universe, adding to the anticipation.
