Spider-Man: Brand New Day Casting Rumor May Confirm Major Spoiler As Movie Eyes $800M Global Opening

One of the biggest Spider-Man: Brand New Day rumours may have just been confirmed by a casting rumour that connects the web-slinger to an unexpected team of characters from the wider MCU.

For well over a year now, rumours that Sadie Sink is playing Jean Grey in Spider-Man: Brand New Day have persisted. While Marvel Studios and Sony Pictures have tried hard to maintain the secrecy surrounding her role, some telltale signs back up these claims.

For example, Sink was spotted on set wearing green and yellow, an apparent nod to Marvel Girl's comic book costume. We also know that Spider-Man: Brand New Day's mystery antagonist will have the ability to control minds, while the Department of Damage Control appears to have taken great interest in the MCU's mutants if Wonder Man was any indication.

Now, reliable leaker @Cryptic4KQual is reporting that Olivia Booth-Ford (The Enfield Poltergeist) will play Jean Grey's sister in the film. Named Sara in the comics, she's a regular human without mutant abilities. This comes amid rumours the DODC will force Jean to work for them by kidnapping Sara.

The insider also revealed that they're unsure whether Jacey Sink, Sadie's little sister who portrayed younger versions of her characters in Stranger Things and The Whale, is in Spider-Man: Brand New Day. That is the rumour, though, suggesting we'll see Jean as a child. 

Billy Clements, who portrayed The Russian, is also said to be a lock for the movie, likely playing Ramrod. 

So, if this rumour is correct, it now seems safe to say that, yes, Marvel Studios will introduce Jean Grey in a Spider-Man movie. We couldn't have imagined Brand New Day setting up X-Men when it was first revealed as a street-level adventure, so now we wait to see if this actually works. 

In other news, @GlobalBoxOffice is reporting, "[Spider-Man: Brand New Day] has crossed $60M in domestic pre-sales and surpassed $120M worldwide. We’re in uncharted territory that cinema has only witnessed once (with [Avengers: Endgame]). $300M+ domestic and $800M+ global weekend are in the cards." 

It's going to be a huge weekend for Spider-Man: Brand New Day then, and as we write this, the movie's social accounts continue to tease fans about Sink's MCU role. The world premiere is tonight, meaning spoilers could start leaking soon...

In Spider-Man: Brand New Day, it's a Brand New Day for Peter Parker. Fighting crime full-time as Spider-Man in a world that doesn’t remember him—and the pressure of seeing his old friends move on without him—sparks a change in Peter he may not have the power to control.

But that transformation might also be the only thing that can stop a shocking new threat to the city and those he loves - a powerful villain no one can even see. The world may have forgotten Peter Parker, but he hasn’t forgotten them.

Spider-Man: Brand New Day's cast includes Tom Holland, Zendaya, Sadie, Jacob Batalon, Jon Bernthal, Tramell Tillman, Michael Mando, and Mark Ruffalo. 

The movie is directed by Destin Daniel Cretton and written by Chris McKenna & Erik Sommers. The film is produced by Kevin Feige, Amy Pascal, Avi Arad and Rachel O'Connor. Executive producers include Louis D'Esposito and David Cain. 

Spider-Man: Brand New Day swings into theaters on July 31.

"It's going to be a huge weekend for Spider-Man: Brand New Day then..."

Now is the perfect time for Disney to ask Sony to sell Spiderman's rights back to Marvel.

800 million dollars opening weekend is insane. If this movie hits with audiences we are guaranteed to be the biggest Spider-Man movie in history and marvel and sonys deal will be cemented forever.

Also the fact that it might make more opening weekend than the entirety of the amazing Spider-Man 2s box office. .

800 million opening weekend. with the high end of the budget, after advertising being like 320 million (most sources think that's over shooting it.

This movie is going to singlehandedly fund Doomsday, and they knew it, that's why they could spend so much on salaries which is where most of that budget is coming from.

@SATW42 - Including marketing, Doomsday is going to have like a 700 million dollar budget. Everyone is going to say they are lucky to break even, but it doesn't take an accounting genius to realize Spiderman making damn near close to 2 billion dollars not only funds itself, but doomsday, and everything doomsday makes is gravy.

The narrative is over for some many people on this site.

@bobevanz - Have you read Ultimate Spiderman by Bendis?

Jean Grey, Cyclops & Wolverine were in one of the first issues.

The Avengers was based on The Ultimates.

Just saying.

I don’t believe it. How do you force a telepath to do anything? Couldn’t she just control the person that’s doing the forcing?
