# Sadie Sink Spotted on ‘Spider-Man: Brand New Day’ Set – Is Gwen Stacy Returning to the MCU?

Recent set photos have sparked fervent speculation among Marvel fans: could Sadie Sink (known for her breakout role in *Stranger Things*) be joining the Marvel Cinematic Universe as Gwen Stacy? The photos, taken during filming of *Spider-Man: Brand New Day*, show a figure with a similar hairstyle and build to Sink, fueling rumors that she’ll be reprising the iconic role. Let’s dive into what we know, the fan reactions, and what this could mean for the future of Spider-Man in the MCU.

## Set Photos Fuel Gwen Stacy Speculation

The buzz began when photos surfaced online appearing to show Sink on the set of the upcoming *Spider-Man* film. The images, quickly circulating on platforms like X (formerly Twitter), depict the back of a woman’s head with a hairstyle reminiscent of Gwen Stacy’s classic look.

Here’s what fans are saying:

However, not everyone is convinced. Some argue the photos simply show a background actor,and the resemblance is too vague to confirm Sink’s involvement. As one user pointed out, it’s “just the back of a random girl’s head.”

## what We Know About ‘Spider-Man: Brand New Day’

Currently,plot details for *Spider-Man: Brand New Day* are being kept tightly under wraps. Marvel Studios is notoriously secretive about it’s projects, and this film is no exception. This makes it tough to definitively say whether Gwen Stacy will even *be* in the movie, or what role she might play.

What *has* been confirmed is a growing cast list. Liza Colón-Zayas (*The Bear*) has joined the production, though her character remains undisclosed. Jon Bernthal is set to return as Frank Castle/Punisher, a fan-favorite character. Mark Ruffalo will once again embody Bruce Banner/Hulk, and Michael Mando is reprising his role as Mac Gargan/Scorpion, marking his first appearance in the MCU as *Spider-Man: Homecoming*.

The return of these established characters suggests a potentially sprawling narrative, potentially tying into the larger MCU Phase 6 storyline. The inclusion of Scorpion, in particular, hints at a possible exploration of Spider-Man’s rogues gallery.

## The Importance of Gwen Stacy in Spider-Man Lore

for those less familiar with Spider-Man’s history,Gwen Stacy isn’t just *any* character. She’s arguably Peter Parker’s first great love, and her tragic death in the comics is one of the most iconic and heartbreaking moments in superhero history. Her story has been revisited in various adaptations, including the critically acclaimed *Spider-Man: Into the Spider-verse* and *The Amazing Spider-Man* films.

Bringing Gwen Stacy into the MCU could open up a wealth of storytelling possibilities. It could explore themes of loss, obligation, and the consequences of being a superhero. It could also introduce the multiverse concept further, potentially connecting to other Spider-Man iterations.
