British actor Noah Jupe is joining the Marvel Cinematic Universe, with the 21-year-old A Quiet Place and Hamnet star reportedly cast in a significant mystery role in Avengers: Secret Wars.
News of Jupe’s casting emerged on September 1, 2026, adding another intriguing name to Marvel Studios’ growing plans for the conclusion of its Multiverse Saga. While his involvement has now been reported, one major detail remains firmly under wraps: exactly who he will play.
That secrecy has immediately created interest around Jupe’s casting. His character is reportedly expected to play an important part in the story, suggesting Marvel may have more planned for the young actor than a brief appearance.
For audiences who recognize Jupe from A Quiet Place, Honey Boy, Ford v Ferrari or the acclaimed historical drama Hamnet, the move represents another major step in a career that began when he was still a child.
It could also introduce him to his largest global audience yet.
Noah Jupe Cast in Avengers: Secret Wars
Jupe has joined the cast of Avengers: Secret Wars, the second half of Marvel’s upcoming two-part Avengers event.
Joe and Anthony Russo are directing the film, which is expected to follow the events of Avengers: Doomsday.
Doomsday is set to bring together characters from several corners of the Marvel universe, including the Avengers, Fantastic Four, Wakanda, New Avengers and X-Men, with Robert Downey Jr. taking on the role of Doctor Doom.
Marvel has revealed considerably less about what happens afterward in Secret Wars.
That makes Jupe’s casting particularly interesting.
His role has not been identified, and Marvel Studios had not publicly provided character details at the time the casting reports emerged.
Reports surrounding the announcement have nevertheless described his role as an important or prominent one.
That could make Jupe more than simply another recognizable actor joining Marvel’s enormous ensemble.
Until Marvel provides additional information, however, his character remains a mystery.
Who Will Noah Jupe Play in Secret Wars?
That unanswered question is likely to dominate discussion surrounding the casting.
Marvel’s Secret Wars draws its name from major comic-book storylines involving numerous superheroes, villains, alternate realities and enormous changes to the Marvel universe.
Because of that history, there is no shortage of characters Jupe theoretically could portray.
Fan speculation has already included possible connections to Marvel’s younger X-Men, Franklin Richards and other characters associated with the multiverse.
None of those theories should currently be treated as confirmed.
Marvel has not announced Jupe as an X-Man, Franklin Richards, the Beyonder or any other specific comic-book character.
The secrecy could also be deliberate because revealing his identity before Avengers: Doomsday reaches theaters might disclose something important about how that movie ends.
For now, the most important confirmed development is straightforward: Noah Jupe is joining Avengers: Secret Wars, and his character has yet to be revealed.
Who Is Noah Jupe?
Although joining Marvel will introduce Jupe to some viewers for the first time, he has already spent more than a decade building an impressive film and television career.
Noah Casford Jupe was born February 25, 2005, in London, England. He is 21 years old.
Entertainment was already familiar territory within his family.
His mother, Katy Cavanagh, is an actress known to British television audiences, while his father, Chris Jupe, works as a filmmaker and producer.
Noah is also the older brother of actor Jacobi Jupe.
Growing up around film did not automatically mean his parents wanted him to enter the industry at an early age. Jupe has spoken in interviews about his fascination with movies as a child and his determination to pursue acting despite understanding how demanding the profession could become.
His career began with television work before quickly expanding into major feature films.
By his early teens, Jupe was already appearing alongside some of Hollywood’s most recognizable actors.
From The Night Manager to Hollywood Films
One of Jupe’s early breakthroughs came with the BBC television adaptation of The Night Manager in 2016.
The spy thriller starred Tom Hiddleston and Hugh Laurie and gave the young actor exposure in a high-profile international production.
His film career accelerated soon afterward.
In 2017, Jupe appeared in Suburbicon, directed by George Clooney, playing the son of Matt Damon’s character.
That same year he appeared in Wonder, the emotional family drama starring Julia Roberts, Owen Wilson and Jacob Tremblay.
Those performances established Jupe as one of the increasingly visible young actors working in Hollywood.
But the role that introduced him to a much larger audience arrived the following year.
A Quiet Place Became a Major Breakthrough
Jupe played Marcus Abbott in John Krasinski’s 2018 horror film A Quiet Place.
The movie follows a family attempting to survive in a world inhabited by creatures that hunt by sound. Emily Blunt and Krasinski played the parents, with Jupe and Millicent Simmonds portraying their children.
The movie became a major commercial and critical success.
Jupe returned as Marcus in A Quiet Place Part II, released in 2021, where his character faced an even greater role in the family’s struggle for survival.
The franchise demonstrated Jupe’s ability to perform in physically demanding scenes while communicating fear and emotion in a story where silence itself was fundamental.
His work also created a connection with Krasinski that stretched back to George Clooney.
Clooney, who had previously directed Jupe in Suburbicon, reportedly spoke highly of the young actor when Krasinski was preparing A Quiet Place.
By that stage, Jupe’s reputation was growing quickly.
Honey Boy Showed Another Side of Noah Jupe
In 2019, Jupe took on one of the most challenging performances of his early career in Honey Boy.
The film was written by Shia LaBeouf and drew heavily from LaBeouf’s experiences as a child actor and his complicated relationship with his father.
Jupe portrayed the younger version of Otis, the fictional character based on LaBeouf, while Lucas Hedges portrayed him at an older age.
The performance required Jupe to handle considerably heavier emotional material than many of his previous roles.
His work earned critical praise and an Independent Spirit Award nomination for Best Supporting Male, helping establish that his success was not limited to conventional child roles.
The same year brought another major film.
Ford v Ferrari Added Another Box-Office Hit
Jupe appeared alongside Christian Bale and Matt Damon in Ford v Ferrari, the acclaimed drama about Ford’s effort to defeat Ferrari at the 24 Hours of Le Mans.
He portrayed Peter Miles, son of British racing driver Ken Miles, played by Bale.
The film became another prominent entry on Jupe’s résumé and further demonstrated the unusual list of directors and actors he had already worked with before turning 15.
Rather than disappearing from the industry as he moved beyond childhood roles, Jupe continued transitioning into more mature projects.
That transition would become increasingly important in the years that followed.
Noah Jupe Continued Growing Beyond Child-Star Roles
Jupe appeared in the HBO psychological thriller The Undoing alongside Nicole Kidman and Hugh Grant in 2020.
He later took roles in projects including No Sudden Move, Dreamin’ Wild and the historical television drama Franklin.
As he entered his twenties, the nature of his career began changing.
He was no longer simply the young son at the center of a family drama.
More adult roles followed, and his association with Shakespearean material became particularly notable.
Jupe appeared as Hamlet in Chloé Zhao’s Hamnet, based on Maggie O’Farrell’s acclaimed novel exploring William Shakespeare, his wife Agnes and the death of their young son.
His work around Hamnet brought renewed attention to an actor who had already spent much of his childhood on major film sets.
By 2026, Jupe was also performing on the West End, demonstrating an interest in stage acting alongside his established film career.
Now Marvel has added another dimension to that trajectory.
Why the Secret Wars Casting Is Significant
Joining a Marvel movie is notable for almost any actor, but the description of Jupe’s role makes this particular casting worth watching.
He is reportedly not simply joining an unnamed background ensemble.
His role is expected to be important to the story.
At 21, Jupe also fits the age range of several younger performers being positioned for Marvel’s future.
That has inevitably encouraged speculation that Secret Wars could introduce him as a character intended to remain in the MCU after the Multiverse Saga ends.
There is no confirmation that this will happen.
But Marvel has historically used major crossover films to establish characters and relationships that become important later.
The timing also arrives as Marvel prepares for a new era involving younger versions of major characters and a renewed focus on properties such as the X-Men.
Whether Jupe is connected to those plans remains unknown.
Avengers: Secret Wars Will Follow Doomsday
Before audiences discover what Marvel has planned for Jupe, the studio must first release Avengers: Doomsday.
That movie is expected to bring together an enormous collection of established Marvel characters around a confrontation involving Doctor Doom.
Robert Downey Jr.’s return to Marvel, this time as Doom rather than Tony Stark, has already made Doomsday one of the studio’s most closely watched upcoming releases.
Secret Wars will then continue the story and bring the Multiverse Saga toward its conclusion.
The title carries enormous expectations among comic-book readers because different versions of the Secret Wars storyline have involved collisions between realities and dramatic changes to Marvel’s fictional universe.
How closely the movie will follow any particular comic remains uncertain.
That uncertainty is exactly why revealing Jupe’s character could potentially reveal more about Marvel’s plans than the studio currently wants audiences to know.
Marvel Fans May Have to Wait for the Answer
The mystery surrounding Noah Jupe’s character is unlikely to disappear immediately.
With Avengers: Doomsday arriving first, Marvel has a strong incentive to keep later developments secret.
That means months of speculation could follow.
Some theories will inevitably sound convincing.
Others will spread across social media as though they have already been confirmed.
Until Marvel Studios, the filmmakers or reliable industry reporting identifies Jupe’s character, those theories remain theories.
What can be said with greater confidence is that the casting represents another significant career move for the British actor.
Jupe has successfully moved from childhood television appearances to acclaimed dramas, major horror films, prestige productions and stage work.
Now he is entering one of cinema’s largest franchises.
For an actor who first attracted attention as a child in The Night Manager and Suburbicon, the journey to an Avengers movie marks another substantial leap.
And because Marvel is keeping his character secret, the biggest question surrounding Noah Jupe may remain unanswered for some time:
Who exactly is he playing in Avengers: Secret Wars?
