Oscar Isaac was missing from the Doomsday cast, but the Moon Knight fans are hoping for his return in the upcoming Avengers movies. Moon Night is not the only character Isaac has played in the MCU adaptations. He has also been the main villain, En Sabah Nur / Apocalypse, in X-Men: Apocalypse (2016). Most recently, he played Spider-Man 2099 in Spider-Man: Across the Spider-Verse (2023). However, his captivating performance in the dual role in Moon Knight earned him a cachet among Marvel fans.

Since the six-episode first season of Moon Knight in 2022, Oscar Isaac has not been a part of any MCU project, and the fans have been wondering about his fate in the universe. He was also absent from the recent Star Wars Celebration despite being an important part of the cast of Star Wars: Episode VII: The Force Awakens and Star Wars: Episode VIII: The Last Jedi as Poe Dameron. Some sources reported that he was absent due to changes in his production schedule, leading fans to anticipate his appearance in Doomsday, which has entered the production stage.

Oscar Isaac is not included in the major cast, which was announced on March 26, 2025. It begs the question, if he will be a part of the upcoming MCU projects and how? Theories are floating all around on the internet, and have led to the speculations that Isaac might return in Secret Wars, slated for a 2027 release.

Let us explore the same.

Until now, Oscar Isaac has not been in any Avengers movies, and as said before, he is not part of the Doomsday cast revealed so far. However, after the livestream, Marvel boss Kevin Feige said that they have yet to reveal more cast members. So, it might eventually include Isaac after all. However, this is only a theory, and there are no confirmed reports of his appearance in the MCU movies.

Earlier, some reports suggested that Isaac would appear in Avengers: The Kang Dynasty. However, his fans were not happy since the project was scrapped. According to the comments from one of the executive producers of Moon Knight, there is no hope for its second season. So, The Kang Dynasty might have offered fans a chance to see Isaac as Moon Knight in an Avengers movie.

While that didn't work out, there's still a chance for Isaac to appear in an MCU project. After Doomsday, Marvel will bring the heroes together again in Secret Wars. If we're going by Marvel Comics, Moon Knight and his variants did appear in some iterations of Secret Wars stories. So, he might appear in the 2027 movie after all.

Another way Oscar Isaac might appear in the upcoming movies is through his presence in the X-Men universe. He may just end up returning as the highly powerful mutant he once played in Fox's movies. There are no confirmed reports on any of these details. Hopefully, the fans will know whether Oscar Isaac will be in Avengers and the character he would play in these movies, soon enough.
