With her starmaking days as Max in Netflix sci-fi series Stranger Things behind her, Sadie Sink is forging a new path as part of the MCU in Spider-Man: Brand New Day.
There have been plenty of early whispers that she is playing a character with ties to the X-Men, including Rachel Summers and Jean Grey. It's the latter that has garnered most buzz, and has led to one Marvel fan spotting an astonishing connection between Max and Jean Grey.
As you can see below, the red track jacket that Max first wore in Stranger Things season 2 bears a striking, uncanny resemblance to the outfit worn by Jean Grey during her comic origin story, as depicted in 2008's X-Men Origins: Jean Grey.
This is crazy like what do you mean the outfit Sadie Sink wore on her first Stranger Things episode is the exact one Jean wore when she first manifested her powers? pic.twitter.com/PfnE0YZGlCJuly 27, 2026
Just a coincidence? Almost certainly. Still, the mystery of exactly who Sadie Sink is playing in the fourth MCU Spider-Man movie isn't dying down. That's only been further intensified by a spoiler snafu at the Brand New Day world premiere – one which may have ruined her character's identity (click through at your own risk).
No matter who Sink is playing, fans can rest easy knowing that they're in for, potentially, one of the best Spider-Man movies of all time. Early Brand New Day reactions describe it as a "mini Avengers film" with Sink herself being described as "perfect."
Spider-Man: Brand New Day, starring Tom Holland, Zendaya, Jacob Batalon, and Jon Bernthal, swings into cinemas on July 29 in the UK and July 31 in the US.
