Sadie Sink Reveals How She Learned About X-Men Casting

Marvel may be carefully building its next X-Men team behind closed doors, but Sadie Sink has revealed that even she does not know exactly who will be joining her. The actress, who plays Jean Grey in Spider-Man: Brand New Day, said she has been kept “a little bit separate” from the casting process for the upcoming X-Men reboot. That includes the search for Cyclops, a role that has recently been linked to Heartstopper star Kit Connor.

Sink’s comments offer an unusual glimpse into how tightly Marvel is controlling the next stage of its mutant plans. Rather than receiving a complete picture of the new ensemble, she said she is finding out about casting decisions through director Jake Schreier. That means the actress at the center of Marvel’s introduction of Jean Grey is apparently discovering some of her future co-stars at almost the same time as fans.

The timing could hardly be more interesting. Spider-Man: Brand New Day has now introduced Sink’s Jean Grey to the MCU, while Marvel is simultaneously putting together the cast for Schreier’s standalone X-Men movie. Deadline previously reported that Connor had emerged as the studio’s choice for Scott Summers, while Samara Weaving has been linked to Emma Frost.

Sadie Sink Is Hearing X-Men News From Jake Schreier

Sink addressed the casting process while speaking with Vanity Fair, explaining that she is not directly involved in every decision being made for the upcoming X-Men. “So, I’m finding out through Jake,” Sink said. “There’s also so many online rumors, but it’s coming together. I think the timing of it is so exciting, and the way they planned it out is really clever just with introducing one of the mutants, a very important mutant through Spider-Man. I think a great cast is coming together, and I think people are going to be really excited about it when it’s all announced.”

That comment is revealing because Marvel has clearly been treating Jean Grey’s arrival as more than a surprise casting reveal. Sink’s character was kept secret throughout much of the promotional campaign for Spider-Man: Brand New Day, and the film has now established her as a mutant with powerful psychic abilities. Entertainment Weekly reports that this version of Jean is presented as a young woman dealing with significant emotional trauma while possessing telepathic and telekinetic powers.

Her introduction also allows Marvel to connect the mutant side of the MCU to an established superhero franchise before the new X-Men movie arrives. That is a considerably different strategy from the old Fox films, where the X-Men existed largely within their own cinematic universe. Marvel can now introduce individual mutants through different corners of the MCU before bringing them together as a team.

Sink was also asked specifically about Connor and the possibility that he could play Scott Summers opposite her Jean Grey. Her response showed that she is being just as cautious as Marvel itself when it comes to unconfirmed casting information.

“Did he? There’s always the rumors, and I just never know what’s official,” Sink said.

That answer does not confirm Connor’s casting, but it does underline how much uncertainty still surrounds the official announcement process. Deadline has reported that Connor is Marvel’s choice for Cyclops, while the studio had not publicly commented on the casting at the time of that report.

Jean Grey And Cyclops Could Define The New Team

If Connor ultimately becomes the MCU’s new Cyclops, his pairing with Sink would immediately give Marvel one of the most recognizable relationships in X-Men mythology. Scott Summers and Jean Grey have been closely connected throughout the comics, with their relationship often becoming one of the emotional centers of the team. Their dynamic has also been explored differently across previous animated and live-action adaptations.

What makes the MCU version particularly interesting is that Jean has already been introduced before the main X-Men film. Marvel therefore does not have to spend the entire reboot establishing her existence, her powers and her place in the world from scratch. The studio can use the new movie to expand her relationships with other mutants while introducing a new version of Scott Summers alongside her.

The approach could also explain why Marvel is introducing Jean through Spider-Man: Brand New Day. Rather than presenting the X-Men as a group that suddenly appears fully formed, the MCU can gradually establish individual mutants and then bring them together. Sink herself described the strategy as “really clever,” particularly because Jean is “a very important mutant” being introduced through Spider-Man.

Jean Grey is one of the foundational characters of the X-Men mythology, having debuted alongside the original team in 1963. Her telepathy and telekinesis have traditionally made her one of Marvel’s most powerful mutants, while her connection to the Phoenix Force has produced some of the most famous stories in X-Men history. The MCU’s decision to introduce her early therefore gives the character plenty of room to develop before the franchise reaches its larger team story.

There is another reason the casting matters. The previous live-action versions of Jean Grey were played by Famke Janssen and Sophie Turner, while Cyclops was portrayed by James Marsden and Tye Sheridan. Marvel now has the opportunity to establish a completely new generation rather than simply recreating the Fox-era dynamics.

Marvel’s Mutant Plans Are Moving Quickly

The casting process for X-Men appears to be progressing at the same time as Marvel expands its broader mutant storyline. Jake Schreier is directing the reboot, with Beef creator Lee Sung Jin and The Bear co-creator Joanna Calo involved in the screenplay. The project has been developing for several years, but recent casting activity suggests Marvel is now moving into one of its most important phases.

The reported addition of Connor as Cyclops would be especially significant because Scott is traditionally one of the team’s primary leaders. His role requires an actor who can handle both the superhero spectacle and the quieter responsibility of commanding a group of characters with very different personalities. Connor’s transition from Heartstopper into projects such as Alex Garland’s Warfare shows that Marvel is not simply looking at him as a young television star.

Samara Weaving has also been reported as being offered the role of Emma Frost, giving Marvel another major mutant character to work with. With Jean Grey already established, Cyclops potentially being cast and Emma Frost entering the conversation, the foundations of the new team are beginning to become easier to see.

For Sink, the immediate future is not limited to Marvel. She also revealed that after filming X-Men, she plans to work on The Marriage Plot, an FX and A24 series. The actress said the end of Stranger Things will make her schedule feel different because she will no longer have the familiar annual cycle of preparing to return to Atlanta for another season.

That change could ultimately benefit Marvel as well. With Stranger Things behind her, Sink has more room to commit to a long-running franchise such as the MCU. Jean Grey is potentially a major multi-film role, and Marvel’s decision to introduce the character before the X-Men team movie gives the studio plenty of opportunities to develop her story over time.

The biggest mystery now is not whether Jean Grey is part of Marvel’s mutant future. That question has effectively been answered by Spider-Man: Brand New Day. The more interesting question is how quickly Marvel will reveal the rest of the team and whether Connor, Weaving and the other rumored additions will form the core cast that carries the X-Men into the MCU’s next era.
