Oscar Isaac Exits Star Wars Event, Fuels Moon Knight Avengers Rumors

Oscar Isaac possibly returning as Moon Knight in *Avengers: Doomsday* might sound like wishful thinking, but recent events are making the rumor harder to ignore. The latest clue comes from a surprising source—his sudden absence from Star Wars Celebration Japan.

Back in February, it was announced that Isaac would be attending the event, sparking speculation about a potential return of Poe Dameron to the *Star Wars* universe. However, just days ago, organizers revealed he had pulled out “due to changes in his production schedule.” While no official reason was given, fans quickly took notice—especially since *Avengers: Doomsday* is currently filming in London.

It didn’t take long for social media to connect the dots:

“He’s gonna be filming doomsday?”

“Dooooomsday”

“Doomsday”

Of course, this is still just speculation. Oscar Isaac wasn’t among the names officially announced for *Avengers: Doomsday*, and Marvel Studios remains tight-lipped on future plans. However, during the recent CinemaCon livestream, producer Kevin Feige did mention that not all cast members were revealed: “We revealed many, not all.” That one sentence keeps the door wide open.

Isaac first played Moon Knight in the 2022 Disney+ series, which ran for one six-episode season. No second season has been announced yet, making a possible cinematic return even more intriguing. And with *Avengers: Doomsday* set for release on May 1, 2026, fans are already buzzing over how Moon Knight could fit into the larger story.

Meanwhile, another curiosity has captured attention online: Robert Downey Jr.’s hair. The actor recently shared a Doctor Doom-themed invitation for his 60th birthday party, reigniting rumors about his mysterious MCU comeback as the villainous Doom.
