In the whirlwind of Spider-Man: No Way Home’s chaos, Tom Holland’s Spider-Man sometimes felt like an afterthought amid multiverse madness. Fans wondered if the beloved web-slinger’s future looked dim. However, hope may be rekindled with the announcement of Sadie Sink joining the cast of Spider-Man 4, titled Spider-Man: Brand New Day. While her character remains a mystery, insiders say she will play a pivotal role that could brighten the franchise’s next chapter. This tease has only intensified curiosity among fans.

Even with details scarce, the question on everyone’s lips remains: will Sadie Sink portray Jean Grey or Gwen Stacy?

Who is Sadie Sink playing? Jean Grey or Gwen Stacy, the answer is in

Sadie Sink had another memorable moment with MTV on the 2025 Tony Awards red carpet, where the reporter cheekily reminded her of their last encounter, calling her “very cagey” about those early Marvel rumors. When asked again whether she would be portraying Jean Grey or Gwen Stacy, the actress delivered a sharp, playful response: “I still say nothing. We are at the Tony Awards. Let us enjoy it!” It was a clear reminder that Sink remains firmly in control of the narrative.

The Emmy-nominated actress attended the event with her brother Mitchell Sink as her date, turning heads while celebrating her nomination for Best Actress in a Play. Her co-stars from John Proctor Is the Villain, Fina Strazza and Gabriel Ebert, were also in attendance, both up for major honors. The trio’s red carpet presence marked a strong night for the critically acclaimed production.

Sadie Sink may be shining under Broadway lights, but online, Marvel fans are casting her into every role imaginable.

The great Sadie Sink role showdown: Gwen, Jean, or someone new?

Sadie Sink has long been a fan-favorite choice for Gwen Stacy. With Zendaya’s portrayal of Mary Jane Watson spanning an entire trilogy, introducing Gwen allows for a new chapter without causing character confusion. Gwen’s narrative offers emotional complexity and real tragedy, which aligns with Sink’s proven acting strengths. Her grounded charm, paired with the depth of Gwen’s storyline, could bring a layered and compelling dynamic to Tom Holland’s Peter Parker in Spider-Man: Brand New Day.

Despite theories suggesting Jean Grey, many fans find it unlikely that one of the central X-Men would be introduced in a Spider-Man film. Instead, speculation has shifted toward Firestar, a mutant with Spider-Man connections. Since Marvel Studios now owns Iceman, and Firestar shares ties with him, some believe she fits into the MCU’s expanding vision. While Firestar is more rooted in mutant lore than Spider-Man’s universe, her crossover potential keeps the fan theories blazing, even with rumors regarding Sadie Sink’s role sometimes pissing fans off.
