Sadie Sink's mystery Spider-Man: Brand New Day role continues to be a hotly debated topic online, though we're still no closer to knowing for sure who the Stranger Things and O'Dessa star will play when she makes her MCU debut.
Jean Grey, Mayday Parker, and Black Cat are just a few of the names we've seen floating around since Sink's casting, but Kristan Harloff is reporting that he's heard a "pretty good guarantee" that Sink will play Gwen Stacy in Spider-Man: Brand New Day.
She's certainly a good fit for Gwen, and with Peter Parker likely heading to college, it makes sense to add a character to the mix who defined those years for him in the comic books. If Sink is playing Gwen, we could see her become Spidey's new love interest or perhaps suit up as superhero herself.
In related news, Daniel Richtman is reporting that "There are more villains in Spider-Man: Brand New Day" than those previously reported.
The greatest love of young Peter's life made her big screen debut in 2007's Spider-Man 3, where she was played by Bryce Dallas Howard. Emma Stone took over the role in 2012's The Amazing Spider-Man and returned in The Amazing Spider-Man 2.
In the sequel, Gwen was killed by Harry Osborn after he became the "Green Goblin" (or a version of him, at least).
The plan was for her to rise from the dead in The Amazing Spider-Man 3, one of many weird creative decisions the threequel looked set to make ahead of Sinister Six. Another involved Norman Osborn's decapitated head and his own miraculous resurrection.
In recent years, the Multiverse has put a new spin on Gwen by making her Spider-Woman (she counts "Spider-Gwen" and "Ghost Spider" among her other aliases). The web-spinning teenager has taken centre stage in the Spider-Verse movies and will even suit up in season 2 of Your Friendly Neighborhood Spider-Man.
Could Spider-Man: Brand New Day be next? We'll have to wait and see, but we've yet to see the definitive version of Gwen on screen, and Marvel Studios has the opportunity to change that. However, Spidey would no doubt be a little reluctant about romancing his college classmate seeing as Peter #2 mentioned he tragically lost her in his reality.
Shang-Chi and the Legend of the Ten Rings helmer Destin Daniel Cretton directs Spider-Man: Brand New Day from a script by Chris McKenna and Erik Sommers. Tom Holland leads a cast that also includes Jon Bernthal, Mark Ruffalo, Zendaya, Sadie Sink, Michael Mando, and Liza Colón-Zayas.
Spider-Man: Brand New Day will be released in theaters on July 31, 2026.
