The Marvel Cinematic Universe is preparing for a massive transition into the “Mutant Saga,” and a new face is set to lead the charge. According to industry reports from December 2025, Millie Bongiovi (formerly known as Millie Bobby Brown) has emerged as the clear frontrunner for a primary role in the upcoming X-Men reboot. This news comes as the actress officially rebrands her professional identity, dropping her former stage name to embrace her legal name, Millie Bonnie Bongiovi. With her time as “Eleven” officially concluded, the timing is perfect for a multi-year Marvel contract.
Kitty Pryde or Jean Grey?
While Marvel has not confirmed a specific character, industry insiders have narrowed the search down to two iconic mutants. Many fans initially pointed to Jean Grey due to Bongiovi’s experience playing a powerful telepath. However, recent reports suggest the studio is leaning toward Kitty Pryde (Shadowcat). Marvel head Kevin Feige has long expressed interest in making Kitty Pryde the central perspective of the new team. This shift would allow the franchise to feel “recognizably different” from previous versions.
A Youth-Focused Vision
Director Jake Schreier, who recently helmed Thunderbolts*, is officially set to direct the reboot. Schreier and writer Michael Lesslie are reportedly developing a “youth-oriented” take on the team. This approach aims to build a new generation of heroes that audiences can grow with over the next decade. By securing an established frontrunner like Bongiovi, Marvel ensures a massive global fanbase for their 2027 release window. The goal is a character-driven ensemble focusing on the internal dynamics of the Xavier Institute.
The Russo Brothers’ Endorsement
The buzz gained significant traction following high-profile comments from Joe and Anthony Russo. The directors worked closely with Bongiovi on the 2025 film The Electric State. During recent press events, the Russos publicly stated that she is “on the list for every project” they have at Marvel. As the duo prepares to direct Avengers: Doomsday and Secret Wars, their influence at the studio is immense. Their vocal support makes her casting feel like an inevitability for the next phase.
Looking Toward the Future
Official casting announcements are expected to arrive in early 2026 as the script enters its final revisions. Fans are also keeping a close eye on her Stranger Things co-star, Sadie Sink, who is also rumored for a mystery Marvel role. If both actresses join the MCU, it would mark a historic talent jump to the world’s biggest film franchise. For now, the prospect of Millie Bongiovi leading the X-Men remains the most exciting development in the post-Multiverse era.
