As Spider-Man: Brand New Day is filming in the UK, speculations continue to circulate about the characters its cast members are playing. One of the most spoken about cast members in Brand New Day is Sadie Sink. As of now, her character remains unknown. Initially, it was believed that Sink was playing the role of Gwen Stacy.
However, Sink's red hair, which flows a bit longer than her shoulders, has led some to believe that she is either playing Mayday Parker, Mary Jane Watson, or Jean Grey. The Stranger Things actress was in London, United Kingdom, where she was spotted with the hairstyle in a restaurant. This hairstyle has people confused regarding her Spider-Man: Brand New Day.
Sadie Sink's Spider-Man: Brand New Day character's hairstyle explained:
A fan account on X (formerly Twitter) posted an image of the Brand New Day actress in a restaurant in London. In the image, we see the actress with red hair, which is similar to Mary Jane Watson/MJ, Mayday Parker, or Jean Grey. For a while, it was also rumored for a while that she would be playing Gwen Stacy. For the uninitiated, until 2014, Gwen was Spider-Man's girlfriend who was killed by Green Goblin.
While the actresses may be wearing a wig to misdirect everyone, it is also possible that she is not Gwen. She might be a more comic-book-accurate MJ, or she is Mayday Parker. For the uninitiated, Mayday is Peter and MJ's daughter.
People who believe that Sadie Sink is playing Mayday Parker theorize that she will serve as a multiversal setup in Spider-Man: Brand New Day. The theory states that she is Tobey Maguire's Peter Parker and Kirsten Dunst's MJ's daughter. Therefore, some think that she will be featured in the Brand New Day post-credit scene, setting her up for Avengers: Doomsday and Secret Wars.
What do we know about Brand New Day?
Rumor has it that Spider-Man: Brand New Day has concluded its Glasgow schedule, and the filming has moved to Pinewood Studios. Brand New Day will see Tom Holland reprise his role as Peter Parker/Spider-Man for the fourth time. It follows him as he tries to adjust to a world that has forgotten him. Therefore, the movie might be darker. Kevin Feige teased the tone like this:
“I think there’s a promise at the end of No Way Home, that for as sad as it is that Peter is forgotten by everyone in his life, we are seeing for the first time in the Tom Holland Spider-Man stories him being a proper Spider-Man. Him being by himself, dedicated to saving the city, and dealing with — for lack of better terms — street-level crime, as opposed to world-ending events.”
Then he further explained how this new tone enables the filmmakers to explore characters not expected before:
“So when you do that, you say, okay, who are the other street-level characters that we’ve never seen him interact with? And of course, I love that The Punisher started in a Spider-Man comic. That great cover... I don’t want to say too much, but Destin — I will say too much — Destin is doing an amazing job right now on that movie, which starts shooting very soon. And he’s got eight or nine comic covers up on his wall in his art department that he is bringing to life in this movie, which is super cool.”
Who do you think Sadie Sink is playing in the MCU? Spider-Man: Brand New Day will be released on July 31, 2026.
