Casting Buzz: Gwen Stacy and Jean Grey

One of the biggest rumors surrounding Spider-Man 4 involves Kiernan Shipka (Mad Men, Chilling Adventures of Sabrina) potentially joining the MCU as Gwen Stacy. While Marvel Studios and Sony Pictures have not confirmed her involvement, the speculation has fueled excitement among fans eager to see the character return to live action.

Meanwhile, Sadie Sink (Stranger Things) is rumored to be cast as Jean Grey, marking a possible introduction of the X-Men into Phase 6. Scoop reports suggest her storyline could involve mind control and ties to Damage Control, though these details remain unverified.

Punisher vs. Hulk Technology Rumor

Another unconfirmed report hints at a dramatic sequence involving Punisher, Hulk, and Spider-Man. Allegedly, Punisher steals advanced Damage Control technology designed to counter Hulk, leading to a potential rampage scene. Marvel has not confirmed this plotline, but the rumor underscores the film’s ambitious crossover potential.

Villains: The Enforcers and More

Industry insider Daniel Richtman claims the Enforcers—Fancy Dan, Frederick Foswell, Montana, and Ox—will appear in Brand New Day. In Marvel Comics, the Enforcers debuted in The Amazing Spider-Man #10 (1964) as criminal operatives opposing Spider-Man. Additional speculation suggests the film could feature up to nine villains from Spider-Man’s rogues’ gallery, though this remains unverified.

Potential Cameos: Kate Bishop and Kamala Khan

Rumors also point to appearances by Kate Bishop and Kamala Khan, who previously shared a post-credit scene in The Marvels. Their inclusion could further set the stage for the Young Avengers storyline, but Marvel has yet to confirm their involvement.

Timeline Placement

An official art book description reveals that Spider-Man: Brand New Day takes place four years after No Way Home. The synopsis notes: “Peter Parker is no more, but Spider-Man is at the top of his game keeping New York City safe.” It also references “an unusual trail of crimes” and “the repercussions of his past,” suggesting a darker tone for Holland’s fourth outing.

What Happens Next?

With Spider-Man: Brand New Day slated for release on July 31, 2026, fans will have to wait for Marvel Studios and Sony Pictures to confirm which of these rumors prove true. Until then, speculation about Gwen Stacy, Jean Grey, and crossover appearances will continue to fuel anticipation for one of Phase 6’s most highly anticipated films.
