Jean Grey in Spider-Man: Who Is the Character Played by Sadie Sink?

On 12 March 2025, Deadline reported that Sadie Sink had joined Tom Holland's fourth web-slinger film, without saying who she was playing. The secret held for more than a year. The answer arrived on screen at the end of July 2026, and Marvel Studios confirmed it at D23 two weeks later. Here is who this Jean Grey is, what she does in the film, what the people who brought her to the screen say about her, where she comes from in the comics and what Marvel has in store for her.

Who is Jean Grey in Spider-Man: Brand New Day?

In Brand New Day, Jean Grey, played by Sadie Sink, is a teenage telepath. Sony's official page describes her as a misguided young girl who has come to New York to look for her older sister, Sara. Her gift lets her transfer her consciousness into other people's bodies and take control of them.

Throughout the first half of the story, her face stays hidden under a hood and a mask, and she only speaks to the hero through the people she possesses. It is around the middle of the film that Peter Parker identifies her: the hero's artificial intelligence finally captures the telepath's face, and a search reveals her name, Jean Grey. This Peter is alone, an adult and forgotten by everyone, as our portrait of the Brand New Day Peter Parker explains. The film follows on from No Way Home: our analysis of what No Way Home changed and our breakdown of its multiverse sum up the starting point, while our guide to what to watch beforehand fills in any gaps.

This Jean is not yet one of the X-Men: she has never met Charles Xavier. Her powers emerged at the same time as her sister's, and their mother abandoned them when the powers showed themselves. The film never actually uses the word “mutant” and makes no reference to the X-Men: it only talks about “mutations”. Products linked to the film are gathered in our Brand New Day selection.

Why is Jean Grey so young in Spider-Man?

Jean Grey is young in Brand New Day because the director chose it. Destin Daniel Cretton wanted the antagonist, younger than Peter Parker, to turn out to be “the loneliest person in the city”, as a way of talking about the escape from reality and the isolation that, in his view, many young people experience today (TheWrap, 4 August 2026). Kevin Feige, head of Marvel Studios, for his part described, during an appearance at USC, a character “very close to Peter's age” who, unlike him, “didn't have a mentor”.

Sadie Sink says the director was above all keen for her to play “a young girl who is suffering” (Variety, 7 August 2026). No precise age has been given for the character: the film refers to a teenager, Sony to a young girl.

The choice is not without precedent. In the comics, a teenage Jean Grey from the past lived in the present, from All-New X-Men #1 (cover-dated January 2013) to Extermination (2018). On the big screen, Sophie Turner had already played a younger Jean than Famke Janssen's in X-Men: Apocalypse (2016).

Why is Jean Grey in Spider-Man?

Jean Grey is in Brand New Day because the film's team asked for her. “It wasn't an obligation, it was a request,” explains Destin Daniel Cretton: Marvel did not impose the character (TheWrap, 4 August 2026). Kevin Feige made the same point on 15 August, at the D23 panel celebrating the hero's 65th anniversary: the choice grew out of the story.

Screenwriters Chris McKenna and Erik Sommers were initially looking for an adversary who could change their appearance and had considered the Chameleon. As Sony had already used him in Kraven the Hunter (2024), they turned to mind control, which led them to Jean Grey, “the perfect character for the role” in McKenna's eyes. The same writer also mentions the Shadow King among the options considered.

Finally, Cretton wanted an antagonist who would act as a mirror to Peter: like him, Jean has lost someone dear, but she only had her sister, whereas Peter was surrounded by people. The team therefore searched the comics for stories devoted to Jean's sister (Deadline, 3 August 2026). The choice also sets up what comes next: according to Kevin Feige, the story “leads towards another very well-known Marvel franchise, created by Stan Lee and Jack Kirby” (Variety, 3 August 2026). The bridges between the two universes are detailed in our article on the links between Spider-Man and the X-Men, and all the characters who orbit the hero are presented on our page about the character universe. Peter, for his part, faces Jean in a redesigned suit, presented in our breakdown of the Fresh Start suit; our Spider-Man costumes let you slip into a web-slinger suit yourself.

Her powers: possession, telepathy, then telekinesis

For most of the film, Jean can only possess people less than about ten metres (33 feet) away, a range on which every account agrees. She gets around the limit by jumping from one body to another, a technique Sara taught her. On screen, she thus takes control of Scorpion (Mac Gargan), MJ, Frank Castle and Bruce Banner, from whom she removes the inhibitor that stops him turning into the Hulk.

Only one mind resists her before her powers surge: Peter Parker's. In the final act, she controls around twenty ninjas from the Hand at once, and they fight as a single body.

Everything changes when Jean realises her sister is dead. Her powers increase dramatically: she creates a psionic field that freezes the inhabitants of part of New York, except Peter, and her telekinesis emerges. Accounts of the film differ markedly on the exact extent of this field, and no figure commands a consensus.

No account records the word “Phoenix” being said on screen, but the film nods to it. For the final fight, stunt coordinator Peng Zhang arranged the ninjas in the shape of a phoenix, and head costume designer Sanja Milkovic Hays used the green and yellow associated with the character for Jean's clothes. Jean wears no superheroine costume: according to Hays, it wouldn't work for the story. Short of a Jean Grey costume, our women's costumes and our figures extend the web-slinger's universe.

Villain or victim? Her real role opposite Peter Parker

Both. For most of the story, Jean is the antagonist: she confronts Peter, wreaks havoc and challenges him through the people she possesses. While possessing MJ, she even makes Peter believe the young woman remembers him, to remind him of what he has lost. Sadie Sink sums up the brief she was given: her character was presented to her as the villain, but a villain who “wasn't really” one (Variety, 7 August 2026).

The twist reveals the real culprit: the Department of Damage Control (DODC), run by William “Bill” Metzger, played by Tramell Tillman, to whom we devote a full feature. It is the agency that abducted Sara and subjected her to the experiments that killed her; its role in the Marvel universe is explained in our article on Damage Control. Without knowing it, the hero even helps the DODC capture Jean: he blocks her powers with his inhibitor while Metzger sedates her. After the capture, Metzger assures Peter that the name “Sara” came into his head while Jean was possessing him; the hero only sees through the lie when he learns that MJ has no memory of her own possession.

The film does not actually show any death caused by Jean, even though she forces a passer-by to walk into traffic: screenwriter Erik Sommers assured The Hollywood Reporter that she is “technically not responsible for any deaths”. To place Jean among the film's other adversaries, from Scorpion to Tarantula, our overview of the Brand New Day villains reviews them all, and our guide to the web-slinger's enemies sets this adversary-turned-victim within the hero's long line of villains.

Sara, the sister Jean is looking for

Sara, played by Olivia Booth-Ford, is Jean's older sister and shares her powers. DODC agents abducted her in a park; she used her powers to get Jean to safety. She died before the film begins, during the agency's experiments. Jean finds out when she is locked in the cell where Sara was held: “V-Max”, the message Sara had sent her, was just the faded label on the air vent grille, the last thing her sister saw. This mystery is unravelled in our article on V-Max.

In the comics, Sara does exist, but she is not a mutant there: mentioned as early as X-Men #22 (1966), she only appears on the page from X-Men #136 (1980). Everything the comics say about her is gathered in our article on Sara Grey, Jean's sister.

The ending: what happens to Jean Grey?

The bus's destination is neither shown nor named. Some fans read it as the road to Charles Xavier's school, but nothing confirms it, and Sadie Sink herself said she did 'not really know yet'. Metzger, meanwhile, slips away in the confusion after Peter is wounded and is nowhere to be found. The only post-credits scene, placed at the very end, does not show Jean: our article on the post-credits scene goes through what it contains.

Will she be back? The 2028 X-Men film

Yes, and it is official. On 14 August 2026, at D23 in Anaheim, Marvel Studios unveiled the cast of its X-Men film, directed by Jake Schreier and due in US cinemas on 5 May 2028. Marvel.com, which lists Sadie Sink first, describes her as the actress who 'made her debut as Jean Grey' in Brand New Day. On stage, she said she was happy to 'finally talk about this character after months of speculation'.

Alongside her, the announced cast includes Kit Connor (Scott Summers), Christopher Abbott (Charles Xavier), Samara Weaving (Emma Frost), Inde Navarrette (Rogue) and Maya Boyd (Storm). The film will be produced by Marvel Studios, which regained the mutants when Disney bought Fox in 2019. To place this future film in the timeline, our list of MCU films in order sets it all out.

The rest is unconfirmed. Jean Grey's presence in Avengers: Secret Wars rests solely on a sentence from journalist Baz Bamigboye (Deadline, November 2025), who placed the actress in 'the next Avengers', shot in London in 2026, before Brand New Day came out. Nor does any announcement place her in Avengers: Doomsday, due in December 2026, in which we are tracking the role in store for the web-slinger. Asked by Variety how many films her contract covers, Sadie Sink declined to answer.

Who has played Jean Grey? The actresses and the films

In Spider-Man: Brand New Day, the actress playing Jean Grey is Sadie Sink, the third lead performer of the role on the big screen after Famke Janssen and Sophie Turner. Two other actresses have played her as a child, in flashbacks.

Famke Janssen played the role in five films of Fox's X-Men saga, two of them as brief appearances: in The Wolverine (2013) she haunts Logan's dreams, and in X-Men: Days of Future Past (2014) she returns for a cameo in the final scene. Sophie Turner played a younger Jean, from a rewritten timeline, in X-Men: Apocalypse (2016) and then in X-Men: Dark Phoenix (2019), in which she is the central character. The latter took $252.4 million worldwide on a budget of $200 million, a commercial failure. On the web-slinger's side, you can rewatch his films with our DVDs of the hero's films, and their order is explained on our page about the Spider-Man films.

In the French dub, Famke Janssen is voiced by Juliette Degenne, Sophie Turner by Kelly Marot and Sadie Sink by Clara Quilichini. In animation, Jean Grey's original voice was Catherine Disher in the 1990s X-Men series, Venus Terzo in X-Men: Evolution, then Jennifer Hale in Wolverine and the X-Men and in X-Men '97 (2024). The actresses behind the web-slinger's heroines, meanwhile, are listed in our article 'Who Has Played Mary Jane?' and on our page covering every cast.

Who is Jean Grey in the comics?

Jean Grey first appears in The X-Men #1 (cover-dated September 1963), created by Stan Lee and Jack Kirby. Under the codename Marvel Girl, she is a founding member of the X-Men alongside Cyclops, Iceman, Angel and Beast, and the only woman in the original team. The daughter of John Grey, a university professor, and his wife Elaine, she grew up in Annandale-on-Hudson, New York. With Spider-Man, co-created by Stan Lee and Steve Ditko in Amazing Fantasy #15 (1962), she therefore shares a co-creator: Stan Lee.

In her early days, she uses only telekinesis; telepathy takes hold between 1968 and 1970, from X-Men #43 to X-Men #65. A 1981 story, Bizarre Adventures #27, rewrites her origin: her powers awoke at the age of 10, when she saw her friend Annie Richardson die after being hit by a car. Marvel ranks her among Omega-level mutants, in telepathy as well as in telekinesis.

The big turning point is Phoenix. In X-Men #100 (1976), Jean flies a shuttle through a solar storm; in #101 (October 1976), by Chris Claremont and Dave Cockrum, she emerges from Jamaica Bay as Phoenix. The Dark Phoenix Saga (X-Men #129 to #138, 1980), by Claremont and John Byrne, sees her consume the D'Bari star and wipe out the roughly five billion inhabitants of one of its planets, before sacrificing herself on the Moon in #137 (September 1980). The planned ending left her alive but stripped of her powers: editor-in-chief Jim Shooter refused to let her survive after destroying an entire planet.

She returns in 1986: Fantastic Four #286 reveals that Phoenix was only a copy created by the Phoenix Force (a twist devised by Kurt Busiek), and Jean reunites the original X-Men in X-Factor #1. She marries Scott Summers, alias Cyclops, in X-Men vol. 2 #30 (March 1994), dies again in Grant Morrison's New X-Men #150 (February 2004), then returns for good in Phoenix Resurrection, a miniseries published from late 2017 to early 2018. A new Jean Grey miniseries, by Jed MacKay and Rogê Antônio, is due out on 25 November 2026.

Her family is a puzzle: Rachel Summers is her daughter in the alternate future of 'Days of Future Past' (X-Men #141, 1981), Madelyne Pryor is her clone created by Mister Sinister (Uncanny X-Men #168, 1983), and Cable, son of Scott and Madelyne, is therefore her stepson.

Jean Grey and Spider-Man: their encounters before the film

The two characters have been crossing paths for nearly sixty years, and on 4 August 2026 Marvel.com published a history of their comic-book encounters. In X-Men #35 (August 1967), the team attacks the web-slinger, mistaking him for the foe they are hunting, and it is Jean, who has stayed behind at the mansion, who discovers that he is not the culprit. In Marvel's internal chronology, their very first meeting is only told after the fact, in Untold Tales of Spider-Man #21 (1997).

Other crossovers punctuate the decades: Marvel Team-Up Annual #1 (1976) with Phoenix, the arc in Spectacular Spider-Man #197 to #199 (1993), in which Jean frees her teammates captured by Professor Power and thanks the hero by calling him a good friend, or X-Men/Spider-Man #1 (cover-dated January 2009), in which Kraven claims on television that the web-slinger is a mutant. In the Ultimate universe, Jean, Storm and Kitty Pryde take the hero to Xavier's in Ultimate Spider-Man #43 (2003), and the young Jean from the past teams up with Miles Morales in All-New X-Men (#31 to #36, 2014-2015); products featuring Miles are gathered in our Miles Morales collection. The meeting of the two clones is told in our article on Dark Web.

On screen, they had already met in animation: in 'The Mutant Agenda' ('Une potion dangereuse' in the French dub), an episode of the 1994 animated series first aired in the United States on 30 September 1995, the hero goes to Xavier's mansion, where Jean, voiced in the original by Catherine Disher, shuts down the Danger Room. In Spider-Man and His Amazing Friends (1981-1983), she appears only in a brief flashback in an episode from 1982; the show's mutant is Firestar, created because the rights to the Human Torch were not available. Long unreleased in France, the series only arrived there in 2020, on Disney+.

The casting secret: from rumour to confirmation

It all began on 12 March 2025: Deadline revealed that the actress was in the film, in a role kept secret, and neither Marvel nor Sony would comment. On 17 July 2026, in a video posted on the film's official accounts, Sadie Sink 'confirmed' that she was neither Spider-Man nor Aunt May. On a podcast, the host set a trap for her by bringing up 'grey jeans', a nod to Jean Grey; she simply replied, 'And what about them?'

The director defended the silence: according to him there was 'a very real reason' not to say who Sadie Sink was playing (Rolling Stone), and 'the film is better if you don't know certain things' (The Hollywood Reporter). On 23 July, the entertainment press picked up a video in which a Brazilian content creator suggested to Tom Holland that Jean Grey could give MJ back her memories of Peter. 'She's not in this film, but that would be pretty cool,' the actor replied. The film proved him wrong.

The breach opened at the world premiere, on Monday 27 July 2026 in Hollywood, two days before the French release. Interviewed by streamer Valkyrae on the official red-carpet livestream, singer Steve Lacy, whose song 'oh yeah?' features in the film, named 'Jean' as his favourite character: 'She's the villain, but there's a reason for her madness.' He said neither her surname nor the actress's name.

After the release, tongues loosened. Destin Daniel Cretton spoke openly about Jean Grey to Deadline and TheWrap on 3 and 4 August, and Kevin Feige explained to Variety that the secret was only meant to give audiences the best possible experience on opening weekend, before saying he was glad Sadie Sink could 'stop dodging the question'. Marvel's official confirmation came on 14 August, at D23. To keep your own identity secret, one of our masks will do the trick.

How Sadie Sink was received in the role

Rather well. According to Rotten Tomatoes' round-up, Alexander Zalben (Comic Book Club) feels she 'clearly stands out', and Edward Douglas (The Weekend Warrior) sees her casting as one of the MCU's most inspired, 'perhaps since' Tom Holland's. At Bleeding Cool, Jeremy Konrad finds her 'as strong as ever'.

The only reservation about the character picked up by Rotten Tomatoes also comes from Bleeding Cool: Kaitlyn Booth writes that “if there’s one thing that breaks the film, it’s her”, while making clear that Sadie Sink “isn’t bad” and “deserves better”; what the critic objects to is the secondary place given to the character’s origin. As of 21 October 2026, the film stands at 90% positive reviews out of 439 counted. Scores and verdicts are broken down in our round-up of the critical reception, and the opening figures in our box-office tracker.

Frequently asked questions

What is Sadie Sink’s role in Spider-Man?

Sadie Sink plays Jean Grey, a telepathic teenager who takes control of other people’s bodies. First presented as the film’s threat, her character turns out to be a victim of the Department of Damage Control, which is responsible for the death of her sister Sara.

Why are two characters called Jean?

Because the film borrows two characters named Jean from the comics: alongside Jean Grey, it features Detective Jean DeWolff, played by Liza Colón-Zayas. Created by Bill Mantlo and Sal Buscema, she first appeared in Marvel Team-Up #48 (1976) and was killed by the Sin-Eater in the very first instalment of the arc that bears her name, in October 1985, the story told in our article on The Death of Jean DeWolff.

Will Jean Grey be in Avengers: Doomsday?

As of 21 October 2026, no official announcement places Jean Grey in Avengers: Doomsday. Only her return in the 2028 X-Men film is confirmed.

Do you need to know the X-Men to follow the film?

No. The film never says the word “mutant”, never mentions the X-Men and presents a Jean who has never met Charles Xavier.
