Fans of the original X‑Men movies still hope their favorite mutants will join the Marvel Cinematic Universe. A fresh rumor now suggests that Famke Janssen Jean Grey return may finally happen in the upcoming Avengers Doomsday film.
The Beyond Reporter posted a tweet on January 12, 2026 claiming that Famke Janssen will reprise her role as Jean Grey. The post included a short video clip that appears to show the actress in a new Marvel costume. If the claim is true, the film will add another iconic Fox‑era X‑Man to the MCU roster.
What Famke Janssen Said
Earlier in October 2025, Janssen told reporters that Marvel had never asked her to return. She explained that she prefers projects where she can control the creative process, such as her Netflix series Amsterdam Empire. She added that she would not rule out a cameo in a fun ensemble movie, leaving a small door open for a possible Avengers Doomsday appearance.
Other Returning Cast Members
The same source also mentioned that Patrick Stewart will appear again as Professor X. Ian McKellen is set to return as Magneto, James Marsden as Cyclops, Kelsey Grammer as Beast, Alan Cumming as Nightcrawler, and Rebecca Romijn as Mystique. In addition, Halle Berry might reprise her role as Storm after a fan asked her directly.
Why This Matters
A Jean Grey return would be a major moment for the X‑Men MCU crossover. Fans have long debated how the Fox characters will fit into the new Marvel timeline. Seeing Janssen on screen again would give the story a stronger link to the original movies and satisfy longtime followers.
Social media users have expressed excitement and disbelief. Many posted comments saying they hope the rumor is true, while others remain skeptical until Marvel makes an official announcement. The buzz shows how much the character still resonates with audiences.
What Comes Next
Marvel Studios has not confirmed any of the casting details. Until the studio releases an official statement, the information stays in rumor territory. However, the growing list of returning actors suggests that Avengers Doomsday could become a massive crossover event.
The possibility of a Famke Janssen Jean Grey return adds fresh energy to the upcoming Avengers Doomsday hype. Whether the actress finally steps back into the role remains to be seen, but the rumor alone has reignited hope among X‑Men fans worldwide.
