Rumblings that Stranger Things star Sadie Sink was being eyed to play Jean Grey in Marvel Studios' X-Men reboot first did the rounds earlier this year. However, we've since learned that she will star in Spider-Man: Brand New Day (and not as the powerful psychic).

Sink's role has been kept under wraps, but on The Hot Mic podcast, John Rocha revealed what he's heard. Apparently, the actress is playing Mayday Parker, the daughter of Tobey Maguire's Peter Parker/Spider-Man.

In the comics, May "Mayday" Parker is the first child of Peter and Mary Jane Parker in a future, alternate universe. In that reality, Kaine reunited the couple with the baby they believed died during childbirth; in a later battle with the Green Goblin, Spidey lost a leg and decided to retire from crime-fighting.

Mayday eventually gained powers of her own as a teenager and donned Ben Reilly's Spider-Man suit to fight Normie Osborn (the Green Goblin's grandson, who set out to restore his family's name as a new Goblin).

If correct, this confirms that Spider-Man: Brand New Day is a Multiversal tale, a decision which makes sense with the movie swinging into theaters between Avengers: Doomsday and Avengers: Secret Wars.

Jeff Sneider, meanwhile, also chimed in to say that Sink's character will likely be a friend to Tom Holland's Peter, filling the void left by MJ and Ned. He added that Mister Negative will be Spider-Man: Brand New Day's villain, with a secondary female villain, likely played by Sarah Snook. Sneider also didn't discount the possibility of Steven Yeun playing the MCU's Martin Li.

We'll see what happens, but there are several convincing signs that Spidey will battle Mister Negative, a newer addition to the character's rogues gallery (he debuted during the "Brand New Day" era in the late 2000s), who filmmaker Destin Daniel Cretton could do a lot with.

"This is news to me. This is news to me," Sink has said of the possibility of playing Jean Grey in Spider-Man: Brand New Day. "No, I have nothing to say about this. The rumours are really cool, though. It's an awesome rumour. I know the character. It's a great character, so that was cool to read."

Spider-Man: Brand New Day has been dated for July 31, 2026, with Shang-Chi and the Legend of the Ten Rings helmer Destin Daniel Cretton directing from a script penned by Chris McKenna and Erik Sommers.

Would you like to see Sink play Mayday Parker in the MCU?

[frick] SONY FOR FORCING MULTIVERSE UPON THIS MOVIE

TheJok3r - 5/16/2025, 4:45 AM

@OptimusCrime - That's the price we have to pay for No Way Home making nearly $2 billion at the box office. There was a rumor last year (or the year before) that Sony was considering having every Spider-Man movie moving forward being a multiverse one.

ObserverIO - 5/16/2025, 5:24 AM

@TheJok3r - Marvel Studios need to cut ties after Secret Wars.

elcapitan - 5/16/2025, 8:03 AM

@ObserverIO - why? So we can go back to TASM/Morbius/Kraven quality filmmaking with a new Spiderman?

CoHost - 5/16/2025, 3:59 AM

Shrek has a daughter

Spidey has a daughter

Will Capt Jack Sparrow gain a daughter?

JustAWaffle - 5/16/2025, 4:40 AM

@CoHost - Didn't Robocop have a daughter? Where's her movie?

dagenspear - 5/16/2025, 4:01 AM

So this confirms it, huh, the villain of Spider-Man: Brand New Day is...

Mephisto.

tippymcfoo - 5/16/2025, 6:55 AM

@dagenspear - No. The villian of Spider-man:Brand New Day is... Sony.

bkmeijer1 - 5/16/2025, 4:30 AM

No thanks. I rather see a Spider-Man 4 that's a sequel to the Maguire/Raimi trilogy set in that universe with Mayday as the lead. Keep multiverse out of this one

JustAWaffle - 5/16/2025, 4:41 AM

@bkmeijer1 - FR. What in the world is this news?

ObserverIO - 5/16/2025, 5:25 AM

@bkmeijer1 - But that is multiverse.

TheVisionary25 - 5/16/2025, 5:37 AM

@bkmeijer1 - yeah , I would prefer that tbh even if that is really a pipe dream at this point lol.

ModHaterSLADE - 5/16/2025, 4:45 AM

I like Mayday Parker, but damn I'm really hoping the next entry stays away from the multiverse and is a more street level focused film.

elcapitan - 5/16/2025, 8:05 AM

@ModHaterSLADE - seriously? Enough whining about this. It takes place between Doomsday and Secret Wars. Of course it’s going to be a multiversal movie. Street level wouldn’t make sense in Battleworld.

TheLobster - 5/16/2025, 4:47 AM

Yeah, I never had an ounce of faith in Sony to not do another multiverse Spidey film. Incompetent [frick]s.

TheJok3r - 5/16/2025, 4:51 AM

@TheLobster - Blame the general audience, not Sony. Their last multiverse movie made nearly $2 billion. People are unfortunately more interested in gimmicks, rather than actual good storytelling.

Thing94 - 5/16/2025, 5:41 AM

Steven Yeun for Mr. Negative I can dig it I like him as Invincible

JustAWaffle - 5/16/2025, 7:29 AM

@Thing94 - That’d actually be perfect casting

SteviesRightFoo - 5/16/2025, 5:48 AM

The year is 2050. We are in the midst of further comic book movie releases incorporating the multiverse into their stories

AC1 - 5/16/2025, 6:07 AM

If - IF - there has to be any multiversal elements in this movie, I'd actually prefer this than just randomly bringing back Tobey and Andrew again and immediately rehashing the Spider-Bros dynamic from NWH.

This way the movie would still focus on Tom's version of Peter as Spider-Man but would give us a supporting character who has ties to what happened before while moving the narrative forward. Also I really like the idea of getting more details about what's happened in Raimiverse Spidey's life and how he's finally balancing having a normal life with being a superhero.

Then save the big Spider-Bros reunion for Secret Wars.

TheVisionary25 - 5/16/2025, 6:28 AM

I mean i could see Sadie play May “Mayday” Parker well and even if I would prefer no multiverse in this , I will still give this a shot if true to see what they are trying to do thematically with it etc.

Also this would corraborate rumors about Marvel wanting a more street level film while Sony wanting it to be Multiverse hence them compromising.

However while i would prefer if Sink play someone like a Gwen Stacy or even Angelica Jones/Firestar , I could also see her play Theresa Parker aswell..

For people who don’t know , Teresa Parker is a CIA agent in the comics and Peter’s long lost sister whose existence was kept hidden by Nick Fury after his parents death so you could have her show up as someone who comes to New York to investigate Martin Li while also to find her rumored brother who is at a low point mentally unknowingly to her considering he has no friends & family anymore after NWH.

Yellow - 5/16/2025, 6:56 AM

Thanks I hate it.

Corruptor - 5/16/2025, 7:07 AM

Pump those Spider-Girl back issues!

That's all that matters.

bobevanz - 5/16/2025, 7:27 AM

@Corruptor - nobody buys comics anymore lmao

SpideyPuffsMJ - 5/16/2025, 7:08 AM

This after that great ending in No Way Home? Why can’t this Spider-Man ever have his own movie?

bobevanz - 5/16/2025, 7:28 AM

EVERY ARTICLE ON THIS SITE IS EITHER RAGE BAIT OR SOME [frick]ING RUMOR.

This place is a joke

Irregular - 5/16/2025, 7:57 AM

Lol WHY WOULD TOBEY MAGUIRES PETER PARKER'S CHILD, SUDDENLY BE IN 616!? Of ALLLLLLLL characters to be stuck in 616, why her!?

Can they at least try to make sense of these dumb ass scoops before we have pitchforks sharpened for Sony!?

So instead of introducing Black Cat, a very well known antagonist/ally to Spider-Man....Mayday Parker is the choice............

RacialPowerman - 5/16/2025, 7:58 AM

So many of yall complain about this movie knowing your still gonna watch it,you're still gonna talk about it. "[frick] Sony,I hate what they did to Spiderman" "This is what we get for making the last movie make so much money,they ruined Spider-Man...still I'm gonna go see it more than once,because I hate Sony and what they did to spiderman"....guys stop pouring your money into things you hate and ruins characters you loved as kids,they only make it because people keep going. It's like paying someone to spray paint your car every month.
