Sadie Sink as Gwen Stacy in Spider-Man: Brand New Day?A Web of Exciting Rumors

The web is buzzing with speculation that Sadie Sink, the breakout star from Stranger Things, might be swinging into the Marvel Cinematic Universe as Gwen Stacy in Spider-Man: Brand New Day.

Recent reports have fans theorizing about her role in the upcoming Tom Holland-led film, set to hit theaters on July 31, 2026. With filming underway in Glasgow, Scotland, and whispers of a multiversal adventure, this casting rumor is sparking excitement.

Here’s a quick little breakdown of everything we know about Sink’s potential role and what it could mean for the next Spidey chapter.

Is Sadie Sink Really Playing MCU's Gwen Stacy?

The rumor mill kicked into high gear when noted film journalist and pundit Kristian Harloff claimed that Sadie Sink is “pretty close to guaranteed” to portray Gwen Stacy in Spider-Man: Brand New Day, as per an Industry source which is close to him and who has a pretty good track record.

This would mark the third live-action appearance of the iconic character, following Bryce Dallas Howard in Spider-Man 3 (2007) and Emma Stone in The Amazing Spider-Man series (2012-2014).

While Marvel Studios and Sony Pictures haven’t confirmed the casting, the speculation aligns with the film’s timeline, as Tom Holland’s Peter Parker is expected to start college, a perfect setting for Gwen, his comic book love interest.

Fans are thrilled at the prospect of Sink, known for her emotional depth as Max Mayfield, bringing a fresh take to Gwen. Her acting chops could add new layers to the character, whether as the classic Gwen Stacy or a multiversal variant like Spider-Gwen, a fan-favorite superhero from the animated Spider-Verse films.

What’s the Multiversal Twist in Spider-Man: Brand New Day?

Spider-Man: Brand New Day is shaping up to be another multiversal adventure, building on the reality-bending chaos of Spider-Man: No Way Home.

Reports suggest Sink could play an alternate-universe Gwen Stacy, possibly even Spider-Gwen, who wields web-slinging powers of her own.

This fits the film’s rumored direction, with Peter Parker navigating a new life after sacrificing his civilian identity. The inclusion of characters like Jon Bernthal’s Punisher and Mark Ruffalo’s Hulk hints at a bold, action-packed story that could weave in multiversal elements without the world-ending stakes of its predecessor.

A multiversal Gwen would allow Sink to flex her action-hero skills, potentially teaming up with Holland’s Spider-Man to face a roster of villains, including Michael Mando’s Scorpion and possibly others like Mr. Negative or Tombstone.

The idea of Sink as a web-slinging hero has fans buzzing with anticipation.

Why Is Sadie Sink the Perfect Fit for Gwen Stacy?

Sink’s casting feels like a match made in Marvel heaven. At 23, she’s the right age to play a college-aged Gwen, and her proven ability to handle complex, emotional roles makes her ideal for a character with Gwen’s depth.

In the comics, Gwen is Peter’s first great love, marked by tragedy, but also a brilliant and resilient figure. Sink’s performance in Stranger Things and films like The Whale shows she can balance vulnerability and strength, qualities essential for Gwen.

The rumor also gained traction after alleged set photos surfaced, showing a figure resembling Sink in Glasgow, though some reports clarified it was a crew member.

Despite the mix-up, the excitement around her potential involvement hasn’t died down, with fans eager to see how she’d fit into Peter’s evolving world, especially with Zendaya’s MJ reportedly taking a smaller role.

What Do Set Leaks Reveal About the Film?

Filming for Spider-Man: Brand New Day is in full swing, and leaked set photos have given fans a glimpse of Tom Holland in a comic-accurate Spider-Man suit, fueling online praise.

While plot details remain under wraps, producer Amy Pascal teased that the film will explore Peter’s choice to prioritize being Spider-Man over his personal life. This sets the stage for new relationships, with Gwen Stacy as a potential romantic or heroic foil.

The cast also includes Zendaya as MJ, Jacob Batalon as Ned Leeds, and newcomers like Liza Colón-Zayas, adding to the film’s star power. Directed by Destin Daniel Cretton (Shang-Chi), the movie promises a fresh yet familiar take on Spidey’s adventures, with Sink’s rumored role as a key piece of the puzzle.

Will Gwen Stacy Steal the Spotlight?

The possibility of Sadie Sink as Gwen Stacy has sent fans into a frenzy, and for good reason.

Whether she’s playing the classic Gwen or a multiversal Spider-Gwen, Sink’s talent could elevate Spider-Man: Brand New Day into a must-see MCU event.

Some Closing Thoughts:

As we await official confirmation, the speculation keeps the excitement alive for Spidey’s next swing.
