SPIDER-MAN: BRAND NEW DAY Rumor Makes A Case For Sadie Sink Playing [SPOILER]

New details about Sadie Sink's Spider-Man: Brand New Day character have been revealed, and all signs are pointing to the Stranger Things alum playing this key Marvel hero.

Social media scoopers appear to have run out of characters when it comes to guessing who Sadie Sink might be playing in Spider-Man: Brand New Day. Still, as we write this, Jean Grey remains the apparent frontrunner as Marvel Studios looks to introduce the first member of its post-Avengers: Secret Wars X-Men. 

Today, we have some additional details about Sink's character from Daniel Richtman. He claims that the Stranger Things star is playing someone who has "a close relationship" with The Punisher in Spider-Man: Brand New Day

Richtman is also reporting that, during the tank scene we saw so much of in set photos, Sink is using her powers to control the minds of those around her, including Liza Colón-Zayas' character. 

This all sounds like something Jean might do. Plus, with the Department for Damage Control reportedly hunting down mutants, we have good reason to believe that the teenager—who has yet to be discovered and taken in by Professor X—is one of their targets. 

It's previously been reported that Tramell Tillman is playing William Metzger, a relatively obscure X-Men villain whose introduction may lay the groundwork for the DODC to utilise Stark Industries technology in the eventual creation of Sentinels. 

Many fans had assumed that the X-Men would just appear in the MCU after Avengers: Secret Wars. Instead, it seems Marvel Studios still intends to reveal that the mutant gene has been activating in certain individuals, starting with Namor, Ms. Marvel, and Wonder Man.

We're sure the expected soft reboot will help make sense of all this, and likely do away with any convoluted explanation for Professor X and Magneto's absence from events before now. Back to Sink, though, and with every new reveal, it seems that Jean Grey is indeed the most likely possibility for her mystery role.

In Spider-Man: Brand New Day, four years have gone by since we last caught up with our friendly neighborhood hero. Peter Parker is no more, but Spider-Man is at the top of his game, keeping New York City safe. Things are going well for our anonymous hero until an unusual trail of crimes pulls him into a web of mystery larger than he’s ever faced before.

In order to take on what’s ahead, Spider-Man not only needs to be at the top of his physical and mental game, but he must also be prepared to face the repercussions of his past!

Shang-Chi and the Legend of the Ten Rings helmer Destin Daniel Cretton directs Spider-Man: Brand New Day from a script by returning Spider-Man franchise writers Chris McKenna and Erik Sommers.

Tom Holland plays Spider-Man in a cast that also includes Jon Bernthal (The Punisher), Mark Ruffalo (The Hulk), Zendaya (MJ), Sadie Sink, Michael Mando (The Scorpion), Tramell Tillman, Marvin Jones III (Tombstone), Jacob Batalon (Ned Leeds), and Liza Colón-Zayas. Avengers: Doomsday star Florence Pugh is expected to reprise her Thunderbolts* role as Yelena Belova.

Spider-Man: Brand New Day will be released in theaters on July 31, 2026.

What the [frick], who cares at this point? Every day we’re hunting for table scraps about Sadie Sink and alas, no scraps

@WhatIfRickJames - not a truer word spoken. All these rumors are making less and less sense.

Does Sadie hold the record for Rumored Character articles?

Movie is 4(?) Months away and not a single piece of Advertising has actually surface.

@Nonameforme - holy crap i thought this was coming out in 2027. you’re absolutely right, shouldn’t we already have seen teasers and trailers by now??

@maxx - On your average film the first trailer will tend to drop around 6months prior, most fall between 5 and 8 months. There has always been exceptions such as those that get teasers a year or more prior but Spider-man has tended to drop trailers later than average. The first one for No Way Home dropped just under four month prior to release if memory serves (as in end of Aug prior to a mid Dec release) basically cos less work needed to build interest in that characters films and they don't want to reach peak hype too early.

IOW it IS due soonish, but specific to Spider-man films no trailer in feb for an end of July release date isn't out of the norm at all and we may not get one till the end of March. Prior to that they have tended to let BTS and drip, drip of rumors and merch leaks do the heavy lifting with early interest.

Oh...I'm convinced she is Jean Grey. 1000%

The weird part isn't that she's playing Jean, but that they have her as a telepath rather than telekinetic

@ProfessorWhy - Jean Grey is both telepathic and telekinetic
ProfessorWhy
ProfessorWhy - 2/21/2026, 11:01 AM
@Wahhvacado - yes, but at the beginning she is only telekinetic , and later was retconned. I was hoping that the MCU would leave some room for her arc.
Wahhvacado
Wahhvacado - 2/21/2026, 11:14 AM
@ProfessorWhy - Ah I see what you mean. I would hope so but feel like there is already too much in this movie to do so. I could see it maybe covered in the X-Men movie but also feel like it'll put more focus on the characters not yet introduced to the MCU
ProfessorWhy
ProfessorWhy - 2/21/2026, 11:36 AM
@Wahhvacado - I've always been inordinately bothered by the portrayal of the x-men and their powers in the movies. I seem to be in the minority on that, but eventually they will introduce the Phoenix storyline and it would be most effective to start Jean as " Marvel Girl "
Wahhvacado
Wahhvacado - 2/21/2026, 11:45 AM
@ProfessorWhy - Agreed, while I loved the X-Men movies when growing up, even then I was really disappointed they didn't go with the original line up. For me Ice Man has always been super interesting and love how his powers develop

I wonder if they're gonna make Tombstone a mutant since he is reported to be the main villain in this.

Richtman / MTTSH are the same person. I tired to share the information a month ago but nobody seems to care that this clown is double dipping subscriptions while pretending to be separate people..

If she isn't Jean or a big name red head they wasted casting for nothing. Same with Tramell
TheVisionary25
TheVisionary25 - 2/21/2026, 11:38 AM
@bobevanz - if both have recurring roles without being big names then that’s not wasted casting…

Also if it’s a one-off then perhaps that is what they wanted?.

Rachel Summers still makes the most sense. She’s the daughter of Fox-Men’s Jean Gray and Scott Summers. Rachel then remains in the new MCU. Kind of like her comic book counterpart.

I wish they’d go ahead and and drop the damn trailer, so we can be spared from this endless barrage of rumors
TheVisionary25
TheVisionary25 - 2/21/2026, 11:45 AM
If true then it is certainly an odd way to introduce Jean into this universe but also fresh & unexpected aswell which keeps fans on their toes about other possible unexpected additions/intros in upcoming MCU projects too…

Also , Sadie’s a great actress so if she is Jean Grey then i have no doubt she could play the complexity of the character well imo if need be.

Oh and it seems like Liza Colon Zayas might be playing a police captain/detective in this who I’m gonna assume is Jean DeWolff which i think could work!!.

P.S: Thinking about it , if Sadie is Jean Grey then I don’t see them putting 2 Jeans in the movie so Liza Colon Zayas could play someone else or an original character.

Convoluted in the keyword. Once they decided to drag in the corpses of the FoX-Men and cast RDJ as Doom, they weren’t left with any other choice but the convoluted path forward. I’m sure fan boys will defend every decision Marvel makes, and maybe comic book nerds will be able to follow along the convoluted route, but chances are the majority of the general audience will get lost along the way at some point.

So Wonder Man got his powers at puberty, and is secretly a mutant, which you’d think would imply there are many other secret mutants as well. Professor X and Magneto have to be older than the teenagers who comprise the X-Men, so maybe their around Wonder Man age?

@MuadDib - Is whoever ends up playing Wolverine (hopefully not Jackman) going to have been a mutant for the past century?

Sadie Sink will be the new Aunt May.

I don't give a single frick about this character though, she'll likely be the another overpowered confident female character who insults and has to save Spider-man and he'll end the film thanking her for it.

Taking into consideration the mind control shenanigans here & now that Jessica Jones is canon to the MCU (again), what if instead of Jean Grey she's actually playing Kara Killgrave?

I don't think Jessica Jones show ever touched upon the Purple Children, so there's an open avenue to introduce Killgrave's kids, plus she's a hero as a member of Alpha Flight.

@1stDalek - Fun fact: The head of Marvel TV said that the movie is connected to Daredevil: Born Again.
