Sadie Sink Already Knows When Marvel’s ‘X-Men’ Starts Filming, and She’s Comparing It to ‘Stranger Things’

Marvel’s mutant reboot has spent the past several weeks generating one casting update after another, but the specifics of when the project actually moves into production have remained frustratingly vague. With director Jake Schreier still working through the script and no official announcement of a cast beyond Sadie Sink’s confirmed debut, fans have had little to go on beyond scattered rumors and industry chatter.

That silence makes any hint from someone actually involved in the project feel significant. Sink, who just made her live-action debut as Jean Grey in ‘Spider-Man: Brand New Day,’ has spent months navigating an unusually tight level of secrecy around her Marvel future, but she’s now offering the clearest signal yet that concrete plans for the ‘X-Men’ film are already taking shape behind the scenes.

Speaking with Entertainment Weekly, Sink revealed that she already knows when filming for Marvel Studios’ ‘X-Men’ will begin, even though she hasn’t seen a script for the project yet. “I know when that’s happening, which is good,” she said, offering a rare piece of concrete information about a film that’s largely existed in speculation until now.

She went on to compare the uncertainty of the situation to her years navigating ‘Stranger Things,’ a show she spent nearly a decade building her career around. “It reminds me of Stranger Things, too, of knowing that you have to do another season, but not knowing what the plan is or not having scripts yet, but having general ideas of where it’s going,” Sink explained. “So I think it’s a formula that I’m very used to.”

That comparison offers some insight into how Sink is approaching this next chapter of her career, treating the ambiguity as familiar territory rather than a source of anxiety. Given how long she spent navigating similarly guarded information throughout ‘Stranger Things,’ the parallel makes sense as a coping mechanism for an actress used to sitting on secrets for extended stretches.

Sink’s road to confirming her Jean Grey casting has been a long one in its own right. She’s previously told Entertainment Weekly that rumors linking her to the character predated her own knowledge of the project entirely, recalling being confused by online speculation about “Sadie Sink” joining Spider-Man before she’d even been cast, only for the offer to arrive just two days later.

Throughout the promotional cycle for ‘Brand New Day,’ Sink consistently described the secrecy surrounding her Marvel role as more intense than anything she’d experienced on ‘Stranger Things,’ telling People that she had so many Spider-Man secrets stacked up that keeping quiet about the Netflix show’s own finale felt easy by comparison.

With ‘X-Men’ currently targeting a 2028 release and Marvel widely expected to unveil a fuller cast announcement at this month’s D23 event, Sink’s confirmation that a production timeline already exists offers fans their first real proof that the project is moving forward on a concrete schedule, even if the specifics remain locked down for now.

For a franchise reboot that’s spent years living almost entirely in rumor territory, hearing directly from its confirmed lead that a filming date is already set marks a genuine step forward. Whether Marvel reveals that timeline publicly anytime soon remains to be seen.
