Is this the casting that has generated the most amount of fan speculation in MCU history?

I’ve never seen this level of theorizing over which character a confirmed actor might play in a project. Information from scoopers changes drastically from month to month, from Jean Grey to Mayday Parker to Gwen Stacy to Shathra, and now back to Jean Grey. Fans also seem to have very different opinions on this. Why do you think the fandom is going much crazier over this casting than others? And please drop your guesses as well.

I think she's playing either Carlie Cooper or Felicia Hardy. The leaks suggest that Sadie's character is a metahuman, but Marvel could easily give those characters superpowers in this movie.

FictionFantom2025-12-20 18:59

I think she’s playing Scream.

Patricia Robertson was 24 years old, close to Sink’s age. She was a military lieutenant, and Sink was wearing cargo pants and combat boots in set pics.
Sink is apparently playing a “shapeshifter”, which the alien symbiote would allow her to do to an extent.

The symbiote spawn/clone from NWH is still out there. Nobody seems to even want to speculate on that because it’s an unpopular idea that’s “been done already”.

ZekeorSomething2025-12-20 19:06

MCU Peter having the symbiote isn’t unpopular. Many people think it’s a good time to do it with how his life’s going and the reason people aren’t speculating it is probably because Peter gets it in Secret Wars and that’s a more fitting time for him to get it.

FictionFantom2025-12-20 20:46

He doesn’t need to get it in this movie, which would explain why Sadie’s character is in Secret Wars: to pass it off to him.

Altruistic_Eye_11572025-12-20 20:03

It's mainly because that post-credits scene is uncertain, and there's a good chance that The Last Dance will de-canonize it.

ChildofObama2025-12-20 19:03

I don’t watch Stranger Things, can she pull off the whole seductress thing?

Not sure if I can picture her as Felicia

FatStoner2FitSober2025-12-20 20:18

She doesn’t play that role in stranger things but I’m sure she can do it. She’s drop dead gorgeous

lundon442025-12-20 18:42

I feel like there was way more talk about TSwift being Dazzler. I was sick of hearing about it.

sidmis2025-12-20 18:47

Not Outside of extremely hardcore MCU fan pages

Caciulacdlac2025-12-20 19:54

What was the one outside of them?

xylotism2025-12-20 20:41

Dr. Doom

Caciulacdlac2025-12-20 20:42

OP is asking about an actor cast in an unspecified role.

TwstdPrtzl2025-12-20 18:58

Giancarlo Esposito in Brave New World probably comes close.

Basic_Adeptness_92732025-12-20 20:47

Really? What characters I don't remember that

Strict-Farmer9042025-12-20 19:34

Probably but only because they usually just come out and say who they’re playing

AJ_CC2025-12-20 19:51

There was a bit around Peter Dinklage in Infinity War.

SeekerVash2025-12-20 19:51

>Why do you think the fandom is going much crazier over this casting than others?

Because she's very clearly perfect casting for MJ Watson and certain groups are enraged by the suggestion.

CRIMS0N-ED2025-12-20 20:57

ppl are way faster to call her Jean than MJ since we already have an MJ here (yeah yeah not the accurate MJ whatever having a second one would still be redundant), especially given she’ll be in doomsday. Now why she’s in a spiderman movie (if it’s even Jean) is beyond me but that’s why we’re gonna find out

Altruistic_Eye_11572025-12-20 20:02

I'd say the most surprising (and worrying) thing about all this is that Marvel... did nothing.

Marvel Studios hasn't promoted the movie with Sink at all and hasn't hyped up her character by saying she's vital or going to be a protagonist in the MCU. And the actress herself hasn't done anything to hype up her character either.

She only gave one interview where she simply said not to focus on the hair color.

Now, why do I say it's worrying? Because a lot of this speculation comes from insiders who have promoted the idea that this character is super secret and other things, which could end up being counterproductive, and we're already seeing it with some people saying they "wouldn't hide something."

Literally, the only reason it's rumored to be Jean is because, supposedly, she's important enough, almost on par with Spider-Man, to "be so secret," when it doesn't make much sense.

This could end in a disappointment like Multiverse of Madness.

Tasty_Cream572025-12-20 20:08

Filming wrapped yesterday. There’s barely anything to promote.

jamesrossurquhart2025-12-20 20:57

Jean makes sense, she’s the one of the few characters from Marvel that would be able to know Spider-Man is Peter Parker and also be able to calm down the Hulk if he goes savage.

Altruistic_Eye_11572025-12-20 21:32

Not so much because any character with telepathy, or one not belonging to the MCU, could discover the spell, or because it's already been explicitly stated that the spell isn't perfect.

And regarding Hulk, we'll have to see, but I have a feeling they won't even defeat him directly. Defeating the villain is how they'll stop Hulk, since he'd be free of control.

I say it's the least likely scenario because of the entire context presented, with a street-level plot mixed with Spider-Man's mystical lore, and the Spider-Totems have nothing to do with mutants and their socio-political storyline. Besides, the character's comment clearly sounds like a threat, something that doesn't fit with Jean, whose kindness is a defining characteristic.

That's why it's so interesting that all the X-Men notice the change in character when she's Phoenix. Presenting her as someone who, if she wants, can ally herself with an assassin as despised as Scorpion doesn't make sense.

jamesrossurquhart2025-12-20 23:29

Yes anyone could theoretically discover the spell but Jean could easily read his mind and find out who he is that way, so from that pov she DOES make sense.

I also haven’t seen any credible leaks to say that Spider Totems have any involvement in the movie.

I haven’t seen any leaks suggesting that Sadie Sink / Jean would be helping or aligned with Scorpion.

The leaks I’ve seen, and then the big one yesterday with a plot breakdown suggests that Jean dislikes Spider-Man because whenever he shows up the he makes things worse. And that Sadie / Jean will be fighting against the Department of Damage Control and Spidey keeps intervening, that’s why she tells him to stay out of her way. It will be The Hand that break Scorpion out of prison while he’s being transferred. Peter is fully consumed by the Spider-Man persona while also struggling with the depression of losing everyone. He gains new powers and can’t control them and goes to Banner for help. The DoDC will eventually evolve into an Anit Mutant Task Force in future, and at some point Jean will help calm a savage Grey Hulk with her powers. Punisher would be there protecting Jean from the DoDC and also uses some type of tank to attack the Savage Hulk. It seems like a lot for one movie but it’s the only leaks I’ve seen that make sense of Jean being in it.

Altruistic_Eye_11572025-12-21 02:01

The totem thing is already somewhat confirmed by the leaked trailer, since you can see scenes of Peter with his powers failing and a scene where he's inside a cocoon; some even mention that he can be seen using organic webbing. All elements of Spider-Man's mystical origin. And in fact, during the teaser, there isn't even a hint that Damage Control or the mutant theme is relevant.

They just appear for a moment and that's it. Also, I did read that rumor you mentioned about a "leaked plot," and even though some YouTubers talked about it, it seems very fake.

The first thing that's happened is that it hasn't been taken down from the internet, and secondly, many have pointed out several contradictions and very obvious errors, such as the fact that a main villain is never established, there's no real reason for Jean to speak so rudely to Peter, since her storyline with Damage Control is forgotten and she only focuses on protecting Peter, no plotline truly concludes and they all end with "to be resolved in the future," or details like the fact that Hulk and Peter's mutations are only due to stress and Jean somehow now has the power to reverse mutations.

In addition, it ignores other rumors from the set, such as the appearance of Chameleon or Rhino, that some of the Damage Control agents would be under mind control, the Hand only appearing in the prison scene as other inmates, the main villain being a shapeshifter, etc.

jamesrossurquhart2025-12-21 03:05

That’s not confirmation at all, not even close to it. That potentially fake plot leak even included those things but it was mutations due to his stress and allowing the spider powers to consume him. Even if that’s not true, those scenes could be part of some type of hallucinations or nightmare sequences.

Jet-Let46062025-12-20 20:12

I'm guessing one of the Spider-Women: Jessica Drew.

Dave_Eddie2025-12-20 20:32

We've literally had dozens of threads a day about how RDJ will be playing Doom. Everything else isn't even close.

MurphyBinkings2025-12-20 20:41

Came here to say the same thing. It's RDJ Doom and nothing else is remotely the same.

CRIMS0N-ED2025-12-20 20:54

yeah but we knew he was doom beforehand, the speculation there was (or still is I guess if you don’t believe them) if it’s a variant/doppelgänger or not, and/or if he’s coming back as iron man as well. Here we don’t even know who sadie is supposed to be

Dave_Eddie2025-12-20 20:56

Read the thread title and then read your answer.

MurphyBinkings2025-12-20 20:57

Ok, and the title of this thread says nothing about specifically speculating about the role they play, just speculation in general.

CRIMS0N-ED2025-12-20 20:59

I get it don’t get me wrong, it just feels like there’s more actual speculation here where for RDJ it was more so severe divisive reactions. Def bigger in scale than sadie but more reactionary, imo anyway.

t-bonestallone2025-12-20 20:39

Mystique

Due_Initial95912025-12-20 20:48

Chameleon is what im guessing

beekeeper_atlamont2025-12-20 20:59

Not really. Any time an actor of any considerable profile is cast without their character being announced, fans will speculate.
