Madelaine Petsch may have wrapped up her scene-stealing turn as Cheryl Blossom on Riverdale, but the 30-year-old star already has her sights set on another fiery redhead — and this time, she’s aiming for the Marvel Cinematic Universe. Speaking at San Diego Comic-Con, Petsch revealed she’d love to play X-Men icon Jean Grey, telling The Direct, “Jean Grey, obviously. Hello. I’ve not seen many Marvel films… but I’ve done my research, and that seems like it’d be really fun.”
Why Madelaine Petsch Could Be the MCU’s Ideal Jean Grey

It’s a casting dream that feels almost too perfect. With her striking red hair, sharp features, and commanding screen presence, Petsch already looks like she stepped straight out of the pages of a Marvel Comics issue. Jean Grey has always been one of the most complex and beloved characters in the X-Men lineup — a mutant with immense telepathic powers, a compassionate heart, and the dangerous potential of the Phoenix Force lurking beneath the surface. Petsch has shown in Riverdale that she can blend vulnerability with a razor-sharp edge, and in The Strangers, she’s shown she can be a leading lady, a combination essential for bringing Jean to life.

Acting chops aside, Petsch’s popularity is another factor that makes her an appealing choice for Marvel Studios. She has a devoted fan base of over 23 million IG followers from her years on Riverdale, where Cheryl’s confident, unapologetic persona became a cultural touchstone for the show’s viewers. That built-in following could help inject fresh energy into the MCU’s upcoming X-Men reboot, drawing in both Marvel loyalists and newcomers eager to see Petsch’s next chapter.
From Riverdale to the X-Mansion: Madelaine Petsch’s Mutant Potential

If Marvel’s rumored new X-Men team is aiming for a youthful, high-profile lineup, Petsch fits the bill. She could hold her own alongside other fan-favorite castings while bringing her own distinctive take to Jean, a character whose arc often anchors the team’s most emotional and high-stakes storylines. From the romance with Cyclops to the inevitable clash with her Phoenix alter-ego, Jean Grey demands an actress who can carry the emotional weight while still delivering superhero spectacle.
Marvel hasn’t announced any official casting for Jean Grey yet, but if Kevin Feige is paying attention to fan chatter and Petsch’s own very public enthusiasm, this could be one of those rare moments when fantasy casting becomes reality. Until then, we’ll be imagining Petsch in that iconic green-and-gold suit, ready to lead the next generation of mutants into the MCU.
