Sadie Sink to join the cast of Avengers: Secret Wars
Relevant bits:
*Spider-Man: Brand New Day* is scheduled to open on July 31. There has been much speculation about [the role Sink has](https://deadline.com/2025/03/sadie-sink-spider-man-movie-1236323300/) in the Spidey film, and frankly, I do not know the answer, but I do know that she’ll join the cast of the next *Avengers* picture that shoots here in London later in 2026.

Shes mj.
At most, maybe Sadie Sink would be playing a multiversal version of MJ. But I'd put money on her being Gwen Stacy, the Raimiverse Mayday Parker, or even Firestar before I would on her being an MJ variant.
(But either way, I want Zendaya to get her mace from Far from Home back and actually use it).
Her Peter (who died on MCU-65) could resemble Holland's character if they wanted some impact to the twist of Sadie's character at the end of.Brand New.Day or.during the mid/Post.credits.
It's only a matter of time before they debut in live-action.
The reverse is far less likely because there are fewer redheads in the world.
Sorry I didn't add the /s I guess.
My current call is Firestar.
That didn't stop Tombstone from appearing in BND though?
Brand New Day is a Sony movie, though. Will Tombstone appear in an Avengers movie, do you think? Personally, I doubt it.
So a grounded movie with ties to the multiverse.
People on Reddit dont like to hear it, but I'm leaning towards Mayday now more than ever. Especially after hearing the Tobey rumors.
The Webbverse on the other hand is more Ultimate-coded.
And the MCU Spider-Man I guess it literally heading towards being Post-OMD/BND-coded.
Tom Holland is nearly 30 playing a 20ish year old Peter
I love the idea of Tobey’s Spider-man being Mayday’s dad, because it both gives us an excuse to see Tobey again, but also something new and refreshing with Mayday as well.
He wanted it to be as vague as possible, like it pretty much doesnt even move on from Spider-Man 3 because all we hear is him and MJ struggled but they make it work. That's pretty much the final shot of the Raimi trilogy.
I'd be surprised if Tobey had a massive change of heart and was down for them just deciding his had a daughter off-screen with MJ.
But yes, they can do whatever they want - I'm just saying I would be surprised if they directly went against what he wanted (and they initially honored) and that he would have enough of a change of heart to take part.
BND will be grounded all things considered. But having Sadie be from a different universe and play someone like Mayday is absolutely in the cards. Her true identity will be revealed in a post credit scene is the most likely bet. If she was Mayday, that will also tie into Tobey in Doomsday. Something like he is trying to find his daughter who got sucked into all this multiverse stuff. Better than him just being there for the sake of being there. He actually has a reason.
While I dont think will be the case, another possibility is Firestar.
IMO i'd rather have her than a grown up Mayday from an alternate Raimi/Tobey-verse.
She's a safe bet, maybe the safest bet Marvel could make when their depiction of the multiverse has been all over the place. Her Spider-Verse version after all is popular, and it successfully sold the idea of multiverse to the masses. Marvel is also doing another version of Gwen in Your Friendly Neighborhood Spider-Man, so it opens up the chance they could borrow from their own depiction of Gwen in animation.
If they're going to do Mayday it's going to be a dead end, because all the rumors of her being tied to Tobey isn't helping. Mayday is not as widely known as Gwen if you're going to sell multiverse, and they're not going back to that Spider-Man 4 under Raimi. Shathra is the least logical choice here she's essentially a Z-list villain nobody knows.
Unless they will do all the hassle to her wearing a wig just to reveal her blonde hair and for what?
They cast a blonde Betty Brant who looks like classic Gwen by the way, and they also cast Marvin Jones as Tombstone even though his alternate version as seen in Your Friendly Neighborhood Spider-Man (voiced by a different person) has dreadlock.
But personally, I'd much rather she play Jean Grey. Because with Jean, she'd be able to restore MJ's memory of Peter.
And if Peter helps her, why wouldn't she help him back? It's perfectly in her character.
Just casually slip it like that for a totally different casting announcement makes me think the writer leaked it by accident.
But I am happy she's not a one off wasted character.
I don't think Mary Jane Watson, while important to Peter Parker, is important enough as a Secret Wars character.
May Parker? Maybe, but the character is redundant to Spider Man. And I don't think the Tom Holland/Zendaya characters are ready for kids. I think this only works if Tom Holland is bowing out of playing the character. There is also the problem of rights, Sony would own May Parker and Marvel won’t want to introduce a character that they do not own.
Jean Grey as an introduction of X-men? They could have kept Sophie Turner in the role, but maybe they just like Sadie better.
Firestar? Too cheesy.
I think Jean Grey would be the smart play, to get the X-men into Secret Wars.
Tom and Zendaya may not be ready for kids, but you know who is, who just popped back up in these films, and who is rumored to be a big part of the next few? — Tobey McGuire.
But something tells me Marvel Studios will take the Amazing Friends angle and go with Firestar.
Bryce Dallas Howard as Gwen Stacy would like a word with you lol
There's a solid chance she's just there to cameo to show off Peter's side of things at the beginning or end of the movies.
But something tells me she'll play Firestar.
Mayday, Spider-Woman, Ghost-Spider. Idc that most of them aren't redheads, i want to see more spider people in the MCU.
