The Shocking New Cast & 10 Major Rumors For Spider-Man 4 ('Brand New Day')

The future of the Marvel Cinematic Universe's (MCU) most beloved web-slinger is finally taking shape, and the casting news is sending shockwaves across the fandom. As of December 2025, the highly anticipated fourth installment in the Tom Holland-led series, unofficially titled Spider-Man: Brand New Day, is reportedly well into its production phase, with filming having kicked off earlier in the year. The latest updates confirm the return of core fan-favorite actors while introducing intriguing new talent and sparking intense speculation about the next major villain Peter Parker will face.

The transition from the world-altering events of Spider-Man: No Way Home to a new, isolated chapter for Peter Parker requires a fresh ensemble, and the casting choices for Brand New Day suggest a grounded, street-level narrative that is both personal and potentially setting the stage for the long-awaited arrival of a key character from the comics.

The Confirmed & Reprising Cast for Spider-Man: Brand New Day

The foundation of the next Spider-Man adventure rests on the shoulders of the returning stars, but their roles have been fundamentally reset following the memory wipe spell cast by Doctor Strange. The core trio is back, though their dynamic will be entirely new, offering a fresh start for the franchise under the creative guidance of Marvel Studios and Sony Pictures.

• Tom Holland as Peter Parker / Spider-Man: The star is officially back, confirming the film is happening and will continue Peter's journey as a completely isolated hero operating without the support of his friends or the Avengers.
• Zendaya as Michelle Jones-Watson (MJ): Zendaya is set to reprise her role, though the nature of her and Peter's relationship is a major plot point, given that she no longer remembers him.
• Jacob Batalon as Ned Leeds: The return of Peter’s best friend is confirmed, but like MJ, Ned's memory of Peter Parker is gone. This leaves the door open for a new dynamic, potentially even exploring the "Hobgoblin" storyline often linked to his comic counterpart.
• Tony Revolori as Flash Thompson: The former high-school bully turned Spider-Man fan is "reportedly" returning, adding another familiar face who now sees Peter Parker as a complete stranger.
• J.K. Simmons as J. Jonah Jameson: While not officially confirmed by the studios, the legendary actor is often listed in the rumored cast, a staple of the new Spider-Man era.

New & Rumored Actors: Key Additions Fueling Fan Theories

The most exciting casting news revolves around the new faces joining the franchise. These additions are the strongest indicators of the film's plot direction, with one name, in particular, dominating the rumor mill and suggesting a major shift in the MCU's landscape.

The Sadie Sink Enigma

The casting of Stranger Things alum Sadie Sink has been the subject of intense fan speculation. She is confirmed to be joining the cast in an undisclosed role. The theories surrounding her character are numerous and include:

• Mary Jane Watson (MJ): The most popular theory suggests she could be the "new" Mary Jane, offering a classic comic book dynamic to the isolated Peter Parker.
• A New Love Interest: A completely original character designed to move Peter past his relationship with the MCU's MJ.
• A Villain/Anti-Hero: Some speculate she could be a young villain, possibly the daughter of a classic Spidey foe, or an anti-hero like Firestar.

Liza Colón-Zayas and the Miles Morales Connection

Actress Liza Colón-Zayas has also joined the cast in a mystery role, which has significantly fueled the long-running rumors about the MCU introduction of Miles Morales. Liza Colón-Zayas is a Puerto Rican actress, and her casting aligns with the cultural background of Miles Morales' mother, Rio Morales. Many believe she is being cast as a member of the Morales family, perhaps an aunt or even Rio Morales herself, setting the stage for Miles' debut in a future project.

The Scorpion's Return?

Actor Michael Mando, who previously appeared as Mac Gargan (Scorpion) in Spider-Man: Homecoming, is also rumored to be returning. With the focus shifting to street-level threats and Peter's isolation, the return of a villain he indirectly created (by giving the Vulture weapons) would provide a perfect, grounded antagonist.

The Future of the Spider-Verse: Beyond Tom Holland and the MCU

While the focus is on Brand New Day, the "Spider-Man" casting universe extends far beyond Peter Parker's current MCU adventures. Sony Pictures continues to build its own cinematic universe (SSU) and the acclaimed animated franchise, keeping the casting pool wide and diverse.

The Animated Universe: Beyond the Spider-Verse

The highly anticipated animated conclusion, Spider-Man: Beyond the Spider-Verse, continues with its established and celebrated cast. This includes:

• Jason Schwartzman as The Spot: The primary villain of the current animated saga.

The Amazing Spider-Man 3 & Andrew Garfield's Legacy

Despite the end of his solo series, the appearance of Andrew Garfield's Peter Parker in No Way Home has led to a massive, ongoing demand for The Amazing Spider-Man 3. While no official confirmation exists, fan-casting is rampant, suggesting roles for villains like Adrian Toomes (The Vulture), Otto Octavius (Doc Ock), and even new versions of Miles Morales and Norman Osborn (Goblin King). This enduring discussion highlights a key aspect of Spider-Man casting: the desire to see all iterations of the character continue their stories.
