How AVENGERS: DOOMSDAY Could Set The Stage For Sadie Sink To Play Mary Jane Watson In SPIDER-MAN 4

With Sadie Sink supposedly set to play Mary Jane Watson in Spider-Man 4, we're taking a look at how Avengers: Doomsday could set the stage for the character's unexpected Marvel Cinematic Universe debut...

Earlier this week, we learned that Stranger Things star Sadie Sink has joined the cast of Spider-Man 4. Given her red hair, it didn't take long for fans (and scoopers) to speculate that she might be playing everyone from Jean Grey to Firestar and Mary Jane Watson.

However, a new report from Jeff Sneider claims Sink will play the latter, meaning the Marvel Cinematic Universe will soon have the "real" MJ. That seems problematic on several levels, not least because it diminishes the work done by Zendaya as Spider-Man: Homecoming, Spider-Man: Far From Home, and Spider-Man: No Way Home's Michelle Jones Watson.

There is one way to make this work, though.

With Spider-Man 4 set to be released between Avengers: Doomsday and Avengers: Secret Wars, it will almost certainly be a Multiversal tale. In fact, if Doomsday ends with the creation of Battleworld, chances are that's where Peter Parker's next adventure is going to be set.

In the comics, when the Multiverse was destroyed and Doctor Doom used the stolen powers of the Beyonders to create a new reality he ruled over, it was essentially a patchwork quilt of worlds, including a very different New York ruled over by a villain known as Regent. There, Spider-Man was once again married to Mary Jane and they even had a daughter, Anna-May "Annie" Parker.

We expect Spidey to be a major problem for Doom in Avengers: Doomsday, so how better to take him off the table than by giving the web-slinger his perfect life? That could involve creating a reality resulting in us getting a "classic" Spider-Man story.

Imagine a Spider-Man 4 where Peter is best friends with Harry Osborn and Mary Jane and Gwen Stacy are battling for his affection. The college student works at The Daily Bugle as a freelance photographer and moonlights as the Amazing Spider-Man, a (mostly) beloved hero. Marvel Studios can deliver a Stan Lee/Steve Ditko/John Romita Sr.-inspired Spidey yarn...before Peter figures out all is not right and his love for his MJ helps him to see through the fake world God Emperor Doom has willed into existence.

Post Avengers: Secret Wars, we've no doubt some of those elements - Gwen and a new Norman Osborn, perhaps - could carry over into the new MCU.

There have been rumblings about Spider-Man 4 being both street-level and Multiversal in nature, so Peter setting out to break free of his false reality gives Marvel Studios - and us - the best of both worlds (literally). The moment has passed for us to get a "classic" take on Spidey in the MCU, what with him being Iron Man's former protege and all, but this approach has real potential.

Ultimately, it's important to note that Sink hasn't been confirmed as MJ and could just as easily be playing Gwen or Black Cat. We'll have to wait and see, but this makes us feel a whole lot better about getting another Multiverse movie next summer.

Spider-Man 4 has been officially dated for July 31, 2026, with Shang-Chi and the Legend of the Ten Rings director Destin Daniel Cretton helming a script penned by Chris McKenna and Erik Sommers.

Or she's just a variant.

@Lisa89 - Hehe. It's so pathetic how you seemingly thrive on the toxicity of these comment sections.

Yet when you're not instigating these toxic comments you complain about them.

Make up your mind.

Lisa89 - 3/14/2025, 3:29 PM

@DarthAlgar - You sure as hell didn't proof read that second sentence. I mean, holy shit.

DarthAlgar - 3/14/2025, 3:35 PM

@Lisa89 - No need. It seems like it's pretty well understood. I know you understood it as well.

Seriously though. Maybe you should get that sand out of your vagina and stop letting people on here who don't agree with you live rent free in your head.

What is this mindset that some of you have where you display certain behaviors but criticize others for doing the same?

TheFinestSmack - 3/14/2025, 3:47 PM

@Lisa89 - I'm not a fan of hers at all, but what's there to be mad about? They're casting a South American that can sing as a South American that sings.

Lisa89 - 3/14/2025, 3:52 PM

@TheFinestSmack - That's precisely the point. With the absolute Hate-On that guys on this site have for Rachel Zegler (you could say she lives "rent free" in their heads), they would complain if she were cast to play Rachel Zegler in "The Rachel Zegler Story". LOL

IAmAHoot - 3/14/2025, 2:23 PM

It wouldn't even take a multiverse for her to play Mary-Jane Watson in the 616 MCU; there's no reason why not.

PatientXero - 3/14/2025, 2:53 PM

@IAmAHoot - It kind of would. Given Zendaya plays Michelle Jones-Watson or “MJ” in the current movies. It’d be a little odd to introduce her as Mary Jane Watson, and not have her be a variant.

IAmAHoot - 3/14/2025, 3:04 PM

@PatientXero - I'm not saying it wouldn't be wierd, I'm just talking logic.

TheVisionary25 - 3/14/2025, 2:31 PM

That could be a really interesting idea honestly which could even go towards being a more psychological approach to the character as he unravels this “reality” that he has found himself in…

I wouldn’t have an issue then with Sadie being “Mary Jane” in that reality but then it does feel wasteful for lack of a better word since she could have played someone like Jean Grey or Firestar as a long running role (unless she didn’t want to sign on for multiple projects)

Anyway , we’ll see but I’m taking all of these [frick]ing rumors with a grain or 2 of salt.

MrDandy - 3/14/2025, 2:34 PM

I really doubt she will be Mary Jane. They already have an MJ Watson in the franchise and she is played by one of the biggest Gen Z stars AND is literally Hollands real life fiancé

People just think this because she has red hair.

krayzeman - 3/14/2025, 3:31 PM

@MrDandy - ^^^this right here^^^

Taonrey - 3/14/2025, 5:29 PM

@MrDandy - shit I highly doubt Hiolland would even be okay with this lol

NonPlayerC - 3/14/2025, 6:32 PM

@MrDandy - a different MJ would be dumb. Id say Tobey Peter's daughter. I don't see the need to bring Gwen in at this point or a duplicate MJ considering they are about to do a soft reboot after secret wars. Firestar maybe but with the previous rumors of them wanting Tobey and Garfield back id say the daughter. She truly looks like she could be Kirsten Dunst's daughter

@JoshWilding

Jason Ritter officially joins Lanterns , character description released aswell.

https://deadline.com/2025/03/jason-ritter-lanterns-dc-series-hbo-1236326771/

MCUKnight11 - 3/14/2025, 2:37 PM

Holland wouldn't allow Michelle to be invalidated because of the IRL engagement. Also, you would think a new supporting cast would stick around for 3 movies like Ned in the previous trilogy. Can't see this being a one and done.

TheVisionary25 - 3/14/2025, 2:46 PM

@MCUKnight11 - it’s that but they should also release they have committed to Zendaya being their take on Mary Jane Watson

If this was post Homecoming , maybe but with the reveal of her being Michelle Jones Watson now after NWH , nope

Plus , you have built this character up for 3 films and her grow so to diminish that would not be good.

ObserverIO - 3/14/2025, 2:49 PM

I have no idea what this movie is about.

Other than Peter has to deal with giving up Peter Parker... in Battleworld somehow? Like how are the events of NWH even relevant if it's a new reality?

It could be that he's a denizen of Battleworld and is a softbooted version of his MCU self who also made the world (the Battleworld) forget who Peter Parker was.
Or it could be that he's a survivor of the multiverse at which point that whole memory wiping thing is irrelevant in this new world, so probably not that.
Or it could be that the multiverse is not destroyed at the end of Doomsday but at the end of Spider-Man 4 instead and this is still set on the regular Earth in the middle of an incursion or multiple incursions with other universes.

The latter actual sounds like the most likely, when you think about it logically.

Him being married to MJ and having a kid however does not sound like he's struggling with no longer being Peter. Sounds like he's doing very very Peter-based things if he's raising a family.

ObserverIO - 3/14/2025, 2:56 PM

Y'know... Having the end of the multiverse at the end of Spidey 4 instead of Doomsday means that they can hedge their bets kind of.

If Doomsday is not a success or flops even, then they could just delay Secret Wars rather than spending lots and lots of money on something that might also flop. Or worse, spending less money on it. You can't skimp on Secret Wars.
They could change the ending to having the universe saved instead of destroyed, but teasing that it's only a temporary fix and that there's a ticking clock on the inevitable final incursion. Then do a Phase 7 building up to Secret Wars when you know that the audience is there again.

@Pampero -

ThorArms - 3/14/2025, 2:54 PM

I still highly doubt that she will be MJ.

PatientXero - 3/14/2025, 2:55 PM

Is she going to be shit on like Shailene Woodley did for almost being cast as MJ is the Amazing Spiderman 2?

DudeGuy - 3/14/2025, 3:28 PM

@PatientXero - yeah.

YonnyLayna - 3/14/2025, 3:38 PM

If its going to be multiversal, maybe Mayday Parker, daughter of Peter and Mj from the Raimi Verse.

Repian - 3/14/2025, 4:14 PM

SummersEssex - 3/14/2025, 4:36 PM

We have MJ...

1stDalek - 3/14/2025, 4:40 PM

it's not MJ, not even Elseworld's MJ because she'd have no connection or impact to this Peter meeting her.

RedFury - 3/14/2025, 5:34 PM

I think it would be a big mistake to screw with the foundation they've already built by undermining characters and plots with the introduction of more "faithful" versions.

It's best to move forward, and not attempt to redo things just for the sake of it. The characters in Hollands trilogy, and so on have been great - don't abandon that, just add to their stories instead. If people want a more "faithful" MJ - it's easy enough to give the next arc of Zendayas character more parallels to that. The same goes for Toms Spiderman.

Move forward, not backwards.

TheVisionary25 - 3/14/2025, 5:42 PM

@RedFury - well said

The next time we see MJ , she could perhaps have reinvented herself

No one in high school is the same later in life so she could dye her hair red , become a model to just make enough money for what she really wants to do etc.

Have it be that after NWH , it always felt like she was missing something without ever truly knowing what it was (it’s Peter) hence she went through this change to see if that could be filled but it hasn’t until she meets Peter again.

RedFury - 3/14/2025, 5:47 PM

@TheVisionary25 - that's it right there. We all change as people as we move through life, and it's easy to apply that to movie characters as well.

You just wrote a good and convincing progression of her character that would work and be seen as an expansion of who she is without abandoning what came before. I really hope they don't give up on what they've built, it would be unfortunate.

TheVisionary25 - 3/14/2025, 5:59 PM

@RedFury - agreed!!

DocSpock - 3/14/2025, 5:37 PM

I think it would be a great bombshell if the big surprise at the end of Doomsday is that she is indeed young Jean Grey.

That would be fantastic.
