After Beau DeMayo’sX-Men ’97showed how well Marvel is capable of handling the team, the prospects of the mutants making it to live-action have certainly garnered enough attention and excitement from fans.

This has resulted in fans making several casting suggestions and promoting various actors for different roles. And among the many actors being promoted by fans,Stranger Thingsstar Sadie Sink has become a popular choice for Jean Grey.

I really like Sadie Sink, but no. Too young.

She’s great but I think she’s too young. When we get the senior X Men members like Jean / Cyclops I think they should at least be 30 if not mid-late 30s.

While the fan debate about her casting is not going to be over soon, it should be kept in mind that her being Jean Grey is just fan recommendations. Although it would be interesting to see the actress in a Marvel role, it’s curious to see howMarvel Studios approachesthe casting of the iconic X-Men characters .
As for now, it will probably be years before the X-Men are truly brought to the live-action verse of the MCU in more prominent roles.
Stranger Thingscan be streamed on Netflix.
