New Report Reveals How SPIDER-MAN: BRAND NEW DAY Trailer Was Shared Online As A Wild Plot Leak Goes Viral

A new report explains how the Spider-Man: Brand New Day trailer leaked online earlier this week. We also have a supposed plot leak for the web-slinger's highly anticipated MCU return.

By JoshWilding - Dec 19, 2025 12:12 PM EST

Earlier this week, the first Spider-Man: Brand New Day trailer leaked online. The quality was appalling, and not everyone was convinced that it was the real deal (especially as believable AI fakes continue to flood social media). 

The Hollywood Reporter has now shared a piece on the leaks, providing some insights into how the footage found its way online weeks, if not months, sooner than Marvel Studios and Sony Pictures would have liked.

The trade explains that, "it escaped from a service studios use to get early feedback on trailers from average moviegoers, who sign NDAs in exchange for looking at stuff early ... The Brand New Day trailer is played on a computer screen that could be logged into such a site."

Despite rumours that the Spider-Man: Brand New Day trailer will play with Anaconda on Christmas Day, Sony hasn't rushed to officially release the preview. Now would be a good time to drop the teaser, but we're sure Marvel Studios doesn't want its Avengers: Doomsday sneak peeks overshadowed by the web-slinger, even if the movie is a co-production with Sony.

In related news, a wild—and likely fake—Spider-Man: Brand New Day plot leak is receiving a lot of attention on social media.

It claims that Peter Parker's powers will continue to evolve, and that Sadie Sink is indeed playing Jean Grey. Tombstone is supposedly the movie's lead villain, and after The Scorpion is defeated, Spidey, Jean, and The Punisher team up to stop an out-of-control Grey Hulk. 

However, pushed to his limit, Spider-Man transforms into Man-Spider and "Jean anchors Peter mentally and helps [him] realise that he can’t only be Spider-Man, but the human side is just as important. Once he realises that, he turns back to normal [and] Bruce finishes the antidote/serum to stabilise Peter's mutation fully."

MJ is dating Harry Osborn, and a post-credits scene shows Tombstone purchasing a sampling of the Venom Symbiote that it seems he intends to bond with Mac Gargan. 

It's a fun read, but we're not buying it (it's way too soon for test screenings). However, adding some weight to at least one part of it is the fact that the "Harris Dickinson-type" we previously heard Marvel Studios was looking for is said to be whoever plays MJ's new boyfriend. That update comes our way from Daniel Richtman.

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. Oh, and yes, this is fake...

Probably fake but God this sounds a lot better on paper than Shathra and Damage Control.

@SpideyPuffsMJ - It really does.

@SpideyPuffsMJ - It’s worth mentioning before filming started that Daniel Destin Cretton is 40-something years old and said he grew up with Spider-Man: TAS, and the rumors were that this movie was being envisioned as an episode of that series “in live action”.

The Man-Spider storyline in that show was part of a storyline called “Neogenic Nightmare” - it was about spidey losing his powers, and Connors finding out his body was mutating and changing. So spidey then goes to Charles Xavier for help on mutation.

In the end, he can’t control the mutation and he turns into the man spider. He only gets help from Dr. Connors and Ashley Kafka and Kraven, and technically Punisher.

The reason I bring this up is people talk about the “Other” spider-totem stuff - but this isn’t that. If Tom’s Spider-Man got bit by a radioactive spider and is causing this to happen, who’s the MCU’s leading Doctor on Gamma radiation? And not to mention, who could Sadie be playing if this movie has to do with “mutation”?

All seems to be lining up for Sadie to be Jean - and her coming to terms with her mutation - as Peter would be, and Banner gravitating to Peter’s situation. Add Frank in there as the TAS influence and yeah…it all lines up.

You post an entire article with all this information just to say at the end you’re not buying it. What even is this website anymore?

@BreakTheCode - what has this website ever been but exactly that with typos and grammar mistakes?

@BreakTheCode - they're just sharing rumors which is what they've always done. A rumor next week may conflict the one from this week. But they post it anyway because its all rumors and this site shares them with us

I dont see what's to complain about. They clearly indicate whats rumor and what's confirmed 🤷🏾‍♂️

@BreakTheCode - This website solely exists to create as much clickable "content" as possible in order to generate ad revenue. That's it.

It doesn't matter if the articles make sense, are grammatically correct, or even factually correct. There's nothing holding this site accountable for any of those things.

That “plot leak” sounds fun if not overtly busy but we’ll see…

If true , Harry dating MJ and thus being introduced to Peter that way is a different yet fun approach imo.

Also I don’t think Sadie is Shathra since she seems to want Peter out of her way hence don’t think we are dealing with Spider Totem stuff but him getting organic webbing & such apparently due to him mutating into Man-Spider and this tying thematically into his arc of closing off his human side to just be super makes sense imo.

Regardless if it’s true or not , I’m looking forward to the film!!.

@TheVisionary25 - man spider in this already packed movie sounds unbelievable. But I would love to see that finally in live action

And having Spiderman 5 tackle the venom stories is a good tie in for the next phase of mcu which is mutants and space stuff with annihilus/nova/knull.

TheVisionary25
TheVisionary25 - 12/19/2025, 12:58 PM
@Vigor - yeah

If this leak is true and unless I missed it , I wonder what causes him to mutate?.
Vigor
Vigor - 12/19/2025, 1:00 PM
@TheVisionary25 - "being pushed to the limit",
Like hes some kind of saiyan

I dont believe it
TheVisionary25
TheVisionary25 - 12/19/2025, 1:04 PM
@Vigor - yeah , that seems odd since he’s been pushed before.

@TheVisionary25 - Willem Dafoe Norman specifically says in No Way Home that he went to F.E.A.S.T. looking for help after he discovered that someone else was living in his home and that neither Oscorp nor his son Harry existed in the MCU. I guess they could hand-wave this away by saying he was lying, but those claims should have been easy enough for anyone to google to verify, so it would be stupid/pointless cover story. To me, the more likely explanation is that this leak is complete BS, and Harry will not be featured at all.

Jean Grey would make sense given the Hulk's fractured psyche. She's one of the few X-Men who remotely has a chance to restrain him.

Sure! Let's not believe Jean Grey is in this movie, because clearly we all believed Tobey and Andrew weren't in NWH

I mean...who would believe Jean is in this movie? I mean come on, PUNISHER, HULK, SCORPION, THE HAND....but Jean Grey!? Nah!!!! Fan head canon explodes at the idea of not meeting Jean Grey a specific way 🙄.

Sarcasm aside, if this leak is real...this sounds pretty damn good for a Spider-Man movie.

This sounds so much more interesting. Spider-man is the perfect vehicle for the mutants to make their entry into this universe. Also the Neogenic nightmare storyline was so scary in the animated series. I am kind of excited to see it play out in live action. Also, it is strange that we might be getting Lovecraftian horror in Spider-man and its not Sam Raimi behind the cameras.

if this is legit, it sounds like a really great Spidey movie. Him turning into man-spider makes sense, with Hulk being in this. Lot of parallels they can use with him and banner. I am willing to bet she is playing Jean, but we won't know until later in the movie. Tombstone being more of a mastermind is interesting though. My guess is that he'll act as the "Kingpin" for the movies, since they can't actually use Kingpin.

I still think it should’ve been Joe Fixit getting involved in a gang war with Tombstone. Banner is doing a Jekyl and Hyde thing at night and has no idea.
TheVisionary25
TheVisionary25 - 12/19/2025, 3:13 PM
@OmegaBlack13 - that would be fun but I feel it would work better if we didn’t already have Smart Hulk.
OmegaBlack13
OmegaBlack13 - 12/19/2025, 6:46 PM
@TheVisionary25 - Smart Hulk is a different thing though. It’s just Bruce in Hulk’s body. Joe Fixit is a different guy entirely.
TheVisionary25
TheVisionary25 - 12/19/2025, 7:03 PM
@OmegaBlack13 - true but it’s another sentiment , intelligent Hulk
OmegaBlack13
OmegaBlack13 - 12/19/2025, 8:18 PM
@TheVisionary25 - Yeah, imo one of MCU Hulk’s biggest missed opportunities is going into the multiple personality things Banner has going on. The first Avengers movie went so far with establishing Hulk is a different being (“The Other Guy”) I’d like them to go more into that. Smart Hulk is still the same character as regular Banner, he’s not even Hulk really. Fixit is his selfishness come to the surface. I think it’d be interesting exploring Banner not having to subdue a “monster” in a destructive sense, but moreso the negative tendencies we all deal with.

Hope it's true, it'll be straight out my fav episode of Spiderman TAS

She is Jean Grey, but there’s a catch to it. Thank you Doctor Stephen Strange.

It would be great if Tombstone defeated Spider-Man and buried him alive. Ultimately, the symbiote bonded with Spider-Man, giving him the strength to rise from the grave.

LOVE Spider-Man TAS. It was my main introduction to the character as a child. A live action take on this series would be incredible.
