Sadie Sink Joins the MCU: First Look at Spider-Man: Brand New Day Set Photos

Marvel fans just got their first real glimpse of Sadie Sink on the set of Spider-Man: Brand New Day, the upcoming fourth Spider-Man movie in the Marvel Cinematic Universe. The sighting marks Sink’s official entry into the MCU, and excitement is already skyrocketing as speculation builds about who she might be playing.

Filming and Production Details

Spider-Man: Brand New Day is directed by Destin Daniel Cretton (Shang-Chi and the Legend of the Ten Rings) and written by Chris McKenna and Erik Sommers, who previously worked on Homecoming, Far From Home, and No Way Home.

Filming officially began on August 3, 2025, in Glasgow, Scotland, operating under the working title “Blue Oasis.” The city’s Merchant City and George Square districts were transformed into a bustling New York City, complete with yellow cabs and fake storefronts.

The film’s cinematographer, Brett Pawlak, reunites with Cretton after Shang-Chi, while the Jackie Chan Stunt Team is once again behind the fight choreography — a promising sign that the action will be intense and practical.

Cast and Returning Faces

Tom Holland reprises his role as Peter Parker, joined by Zendaya (MJ), Jacob Batalon (Ned), Jon Bernthal (The Punisher), Mark Ruffalo (Bruce Banner), Michael Mando (Mac Gargan), and Marvin Jones III, who has been confirmed to play Lonnie Lincoln, better known as Tombstone.

Sadie Sink’s character has not yet been revealed, but fans are already theorizing possible roles — from Gwen Stacy to a new original character tied to the multiverse.

Newcomers Tramell Tillman, Alex Breaux, and Nell Fisher also join the cast, alongside returning MCU figures, hinting that Brand New Day may tie into the larger Phase Six storyline.

Possible Villains: Mister Negative and Rhino?

Set photos have given fans a few major clues about the movie’s villains. Vehicles marked with a red demon logo were spotted on set, leading Total Film’s Bradley Russell to speculate that Mister Negative could make his MCU debut.

Meanwhile, an enormous rhinoceros-shaped prop was seen on location, suggesting Rhino might return in some form — potentially as a reimagined version of the villain teased in The Amazing Spider-Man 2.

Tom Holland’s On-Set Injury and Filming Locations

Filming also took place in Surrey’s Brookwood Cemetery and Pinewood Studios in Buckinghamshire. Later in September, production briefly paused when Tom Holland suffered a mild concussion performing a stunt. He recovered quickly, and the schedule remained on track.

Additional scenes were filmed in Basingstoke, England, where Holland was joined by Michael Mando, confirming Mac Gargan’s return to the Spider-Man universe.

Why Fans Are Excited About Sadie Sink’s MCU Debut

Sadie Sink, best known for her role as Max Mayfield in Stranger Things, has built a reputation for powerful and emotional performances. Her casting in Spider-Man: Brand New Day signals Marvel’s commitment to bringing fresh talent into the fold.

While her role remains under wraps, her first on-set appearance — alongside Holland and what appears to be a Demogorgon-style villain tease in the concept art — has already set the internet ablaze.

The Future of Spider-Man: Brand New Day

Spider-Man: Brand New Day will be the 38th film in the Marvel Cinematic Universe, serving as both a direct sequel to No Way Home and a launchpad for new Phase Six storylines.

With Cretton’s direction, Sink’s addition, and early hints of multiple villains, this could be the most ambitious Spider-Man entry yet, blending high-stakes storytelling with grounded character drama.

As filming continues across the UK, fans are eagerly awaiting Marvel’s official synopsis — and, most importantly, the reveal of who Sadie Sink will play when she officially swings into theaters.
