Noah Jupe is officially entering the Marvel conversation after landing a mystery role in Avengers: Secret Wars, adding another rising young star to one of the biggest superhero movies currently in development.
The 21-year-old British actor, widely recognized for A Quiet Place, Hamnet and The Undoing, has been tapped for the sixth Avengers movie. The casting news emerged on September 1, 2026, with reports indicating that Jupe’s undisclosed character could have an important part in the story.
Marvel has not revealed who he is playing.
That secrecy has immediately generated theories among fans, particularly because Secret Wars is expected to bring together characters from multiple corners of the Marvel Cinematic Universe.
With production preparing to move forward, here’s what is actually known about Noah Jupe’s Avengers role and what remains speculation.
Joins Secret Wars
Jupe has been cast in Avengers: Secret Wars, the follow-up to 2026’s Avengers: Doomsday.
The Russo brothers, Anthony and Joe Russo, are directing the film after returning to Marvel for the two-part Avengers event.
Reports describing Jupe’s casting say his character is being deliberately kept secret. More significantly, the role is expected to be important rather than a minor appearance.
Marvel has not publicly provided a character name or description.
That makes any claim that Jupe is definitely playing an established comic-book hero premature.
Who Could He Play?
The secrecy surrounding the casting has naturally encouraged speculation.
One of the most prominent theories is that Jupe could portray an older Franklin Richards.
Franklin is the son of Reed Richards and Sue Storm of the Fantastic Four and possesses extraordinary reality-altering abilities in Marvel Comics.
The character’s comic history also gives him connections to major multiverse stories, making him an understandable candidate for a film titled Secret Wars.
Some fan discussions have alternatively suggested Jupe could play the X-Men character Bobby Drake, better known as Iceman.
Neither theory has been confirmed.
Reports announcing Jupe’s casting describe his character only as a secret or mystery role.
Franklin Richards Theory
The Franklin Richards theory has gained particular attention because of the character’s importance in Marvel mythology.
Franklin can manipulate reality and has been depicted as one of the Marvel universe’s most powerful individuals.
He also has an important connection to the 2015 Secret Wars comic storyline.
That story involves the destruction of universes, the creation of Battleworld and Doctor Doom gaining extraordinary power.
Franklin ultimately becomes important to rebuilding what has been destroyed.
The MCU does not necessarily follow comic storylines exactly, so the comics cannot confirm Jupe’s identity.
For now, Franklin Richards is a theory rather than an announced casting.
Not Doomsday
Another important distinction concerns which Avengers movie Jupe has joined.
The current casting reports specifically connect him with Avengers: Secret Wars rather than Avengers: Doomsday.
Doomsday arrives first, with its theatrical release scheduled for December 18, 2026.
That movie brings together an enormous collection of Marvel characters, including Avengers, Wakandans, the Fantastic Four, New Avengers and familiar X-Men characters. Robert Downey Jr. plays Doctor Victor von Doom.
Secret Wars follows approximately one year later.
Jupe’s involvement in that second movie does not automatically mean he will appear in Doomsday.
No such appearance has been confirmed.
Secret Wars Release
Avengers: Secret Wars is currently scheduled to arrive in theaters on December 17, 2027.
The movie will continue the story established by Doomsday and bring Marvel’s Multiverse Saga toward its conclusion.
Anthony and Joe Russo are overseeing both films.
The brothers previously directed Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame.
In a September 2026 interview, the Russos revealed that they were finishing work on Doomsday while beginning early preparation for Secret Wars.
Jupe is therefore joining Marvel at a particularly important point in the franchise.
Sadie Sink Connection
Jupe’s Marvel casting also creates an interesting reunion with Sadie Sink.
The two actors recently starred opposite each other in a West End production of Romeo and Juliet at London’s Harold Pinter Theatre.
Jupe played Romeo while Sink portrayed Juliet.
The production ran from March through June 2026 and marked Jupe’s professional stage debut.
Now both performers are connected to Marvel’s expanding superhero universe.
Entertainment Weekly reported that Sink has already entered the MCU as Jean Grey, giving their reunion in the Marvel world an additional layer of interest.
Exactly how closely their characters will interact in Secret Wars remains unknown.
Who Is Noah Jupe?
Jupe has already built an extensive acting résumé despite being only 21.
Born in London in February 2005, he began appearing on television as a child before making the transition into major films.
His early television credits included Penny Dreadful and Downton Abbey, followed by an appearance in The Night Manager.
His film career accelerated with roles in Wonder and George Clooney’s Suburbicon.
But his biggest early breakthrough came in 2018.
Jupe played Marcus Abbott in John Krasinski’s A Quiet Place, appearing alongside Emily Blunt and Millicent Simmonds.
He returned as Marcus in A Quiet Place Part II.
Bigger Roles
Jupe continued building his reputation through projects that were very different from the horror franchise.
He appeared in Ford v Ferrari alongside Christian Bale and Matt Damon and played a fictionalized younger version of Shia LaBeouf’s character in Honey Boy.
His performance in Honey Boy brought particular critical attention.
Jupe later starred alongside Nicole Kidman and Hugh Grant in HBO’s mystery drama The Undoing.
More recently, he appeared in Hamnet, the acclaimed Shakespeare-related drama, before working opposite Hugh Jackman in The Death of Robin Hood.
His move into the MCU therefore follows years of increasingly high-profile film and television roles.
A Quiet Place Return
Jupe’s schedule is becoming even busier.
Alongside his new Avengers commitment, he is returning to another major franchise.
Reports surrounding his Marvel casting confirm that Jupe recently finished production on A Quiet Place Part III.
His return continues the story that originally helped introduce him to a much larger international audience.
He is also attached to other upcoming projects, including the Netflix thriller Play Dead.
The combination of A Quiet Place and Avengers places Jupe firmly within two major Hollywood franchises.
Why His Role Matters
Marvel’s decision to keep Jupe’s character hidden is one of the most intriguing elements of the announcement.
Secret casting does not automatically mean he is playing an established superhero. However, reports suggesting that his role will be important make the mystery more significant.
Secret Wars also provides almost unlimited possibilities.
Marvel Comics has published two major storylines under that title, including the influential 2015 version centered on collapsing realities and Doctor Doom’s Battleworld.
The MCU has spent years introducing multiverse concepts, alternate realities and incursions.
Avengers: Doomsday is expected to push those ideas toward a massive collision before Secret Wars continues the story in 2027.
A powerful character such as Franklin Richards could logically fit that framework, but Marvel may have something completely different planned for Jupe.
What Is Confirmed?
For readers searching for “Noah Jupe Avengers,” there is now a clear answer: yes, Noah Jupe is joining the Avengers franchise.
He has been cast in Avengers: Secret Wars, with his role reportedly expected to carry real importance in the movie.
What remains unknown is his character.
Franklin Richards and Iceman are among the names being discussed by fans and entertainment writers, but Marvel has not confirmed either possibility.
With Secret Wars scheduled for December 17, 2027, audiences may have a considerable wait before the mystery is officially solved.
For Jupe, however, the casting already represents another major step—from A Quiet Place child star and acclaimed dramatic actor to a new face in the Marvel Cinematic Universe’s biggest upcoming crossover.
