The upcoming movie will reintroduce Jean Grey to the MCU for the first time since the Fox‑era films, which featured Famke Janssen in seven releases from 2000 to 2019. Comics readers know the character’s origin in X‑Men #1, created by Stan Lee and Jack Kirby.

Sadie Sink’s casting has reignited discussions about Jean Grey’s legacy.

Reintroducing Jean Grey in the MCU allows Marvel to reimagine the character’s origin and powers, moving away from the Fox-era portrayal by Famke Janssen, who appeared in seven films between 2000 and 2019. This new interpretation will be shaped by Marvel Studios’ creative direction, with Sadie Sink positioned to explore Jean Grey’s evolution in a contemporary cinematic context.
