Hollywood is buzzing after Stranger Things breakout star Sadie Sink was reportedly spotted on the set of Spider-Man 4, sparking rumors that she’ll join Tom Holland’s Peter Parker in the Marvel Cinematic Universe’s next web-slinging adventure. Insiders claim Sink’s casting is a “major piece” of the film’s plot—and Holland is already hyping it as “the wildest Spider-Man story yet.”
A source close to production revealed that Sink, known for her emotional powerhouse role as Max Mayfield in Stranger Things, has been in talks with Marvel Studios for months. “This isn’t just a cameo,” the insider shared. “She’s playing a character that will redefine Peter’s journey—and the MCU’s future.” While Marvel is keeping details under wraps, leaks suggest Sink could portray a fan-favorite comic figure like Black Cat, Spider-Gwen, or even a gritty new villain.
Tom Holland fueled excitement during a recent interview, joking, “Let’s just say Sadie’s character… isn’t here to make friends.” He added, “After No Way Home, we’re taking risks that’ll blow minds. This isn’t your little brother’s Spider-Man.”
Fans are already theorizing wildly online. Could Sink’s role tie into the multiverse saga? Is she setting up the Young Avengers? Or will she bring a darker, street-level edge to the franchise? One thing’s clear: her chemistry with Holland has Marvel bosses “thrilled.” A set photographer (who asked to remain anonymous) teased, “Their scenes together? Electric. Sadie’s bringing something raw and real to this world.”
Spider-Man 4 is set to begin filming this fall, with a rumored 2025 release. The movie will follow Peter Parker rebuilding his life after the world forgot him—but with new allies, enemies, and maybe even romance on the horizon.
