Noah Jupe has reportedly joined Avengers: Secret Wars, but Marvel is keeping his character hidden. Deadline first reported the casting on September 1, 2026, and the report was later covered by TheWrap and ComicBook.com. The only clear detail so far is that the role is expected to matter to the story.

Marvel has not announced Jupe’s role, and the studio’s public movie listings do not add any extra information about him.

What has actually been reported?

The report says Jupe is joining the cast of Avengers: Secret Wars in a secret, prominent role. ComicBook.com describes it as a part expected to play a key role, while TheWrap says the character is still unknown. Neither report names a hero, villain, mutant, or member of the Fantastic Four.

“Key role” tells us the part may have a meaningful place in the story, but it does not tell us who Jupe is playing or how much screen time he will have. There is no official Marvel casting announcement for him yet, and there is no confirmed first look.

Who is Noah Jupe?

Jupe is a 21-year-old British actor whose credits include A Quiet Place, A Quiet Place Part II, Honey Boy, The Night Manager, The Undoing, and Hamnet. He has worked in horror, family drama, television, and historical film, so the casting does not point to one obvious Marvel lane.

His A Quiet Place connection is the detail most fans will recognize. Jupe played Marcus, one of the Abbott family’s children, in the post-apocalyptic horror films. His role in Hamnet also brought him back into the conversation around major awards-season movies, which helps explain why this casting immediately drew attention even without a character name.

What are fans guessing?

The missing character has already started a familiar Marvel guessing game. The theories currently circulating include an X-Men character, Iceman, Franklin Richards, the Beyonder, and Molecule Man. Each idea comes from a different part of the comics or from the age of the actor, not from a confirmed casting detail.

The X-Men theory is tied to Marvel’s plan to build a younger mutant cast around actors close to Jupe’s age. The Iceman guess is a specific version of that theory. Franklin Richards is another popular possibility because the Fantastic Four are central to the next Avengers films, while the Beyonder and Molecule Man are both connected to major Secret Wars comic-book storylines.

None of those guesses has been confirmed. The casting report does not mention any of those characters, and Marvel has a long history of protecting its biggest crossover roles until the studio is ready to show them.

How does Secret Wars fit into the release plan?

Marvel lists Avengers: Doomsday for December 18, 2026, followed by Avengers: Secret Wars on December 17, 2027. Joe and Anthony Russo are directing both films, making Secret Wars the second half of a two-movie event rather than a separate story with no connection to Doomsday.

That timing gives Marvel a practical reason to keep Jupe’s role quiet. If his character connects directly to the ending of Doomsday, naming him now could reveal what survives, who changes, or which corner of the Marvel universe becomes important in the sequel. That is an explanation for the secrecy, not proof of any particular theory.

Could Noah Jupe be playing an X-Men character?

It is possible, but there is no evidence strong enough to call it a scoop. Marvel has announced several younger actors for its next X-Men film, and Jupe fits the general age range. That only makes the theory plausible; it does not make it likely or confirmed.

The same standard applies to Franklin Richards, the Beyonder, and Molecule Man. All three would make sense in a Secret Wars story, especially if the films borrow ideas from Jonathan Hickman’s 2015 comic event. But the movie has not been described in enough detail to connect Jupe to any one of them.

The new report arrives while Marvel is already building a large casting conversation around its next projects. Our Avengers: Doomsday podcast coverage tracks the studio’s current rollout, while Adam Driver’s reported X-Men role, Kit Connor’s Cyclops casting report, and Samara Weaving’s Emma Frost casting show why every new Marvel actor now triggers a wave of theory posts.

What should fans watch for next?

The next useful update would be an official Marvel cast listing, a production announcement, or a trailer that gives Jupe’s character a recognizable clue. Until then, the honest headline is simple: Noah Jupe is reportedly in Secret Wars, his role may be important, and nobody outside the production has identified the character.

For now, treat the fan theories as part of the fun rather than leaked information. Marvel has left enough room for almost any possibility, which is exactly why the casting news is getting attention before Secret Wars has even started production.
