Millie Bobby Brown is no stranger to rumors about her involvement in MCU things. Her visit to the set of Avengers: Infinity War had fans convinced she was joining the franchise. Rumors persisted that Brown was set to play Eternals Peter Pan analogue, Sprite, and while Brown teased that she’d had discussions with Marvel Studios, that role went to Lia McHugh and Brown has spent the last several years filming Stranger Things Season 5, limiting her availability for other major projects.
The return of the directors Anthony and Joe Russo to the MCU to helm Avengers: Doomsday and Avengers: Secret Wars has lead to renewed rumors and speculation that Brown, who the lair directed in the Netflix’s Electric State, would join the MCU now that shes closed the book on Stranger Things. The directing duo have made no bones about their admiration for the young actress, saying they would “put her in anything” they make moving forward.
Millie is on the list for every project. You just can’t ask for a bigger star right now. And [she is] somebody who is passionate about the work, passionate about promoting the movie, passionate about getting up every day and coming to set, making the crew feel good, she has adopted hundreds of dogs, she brings them to set with her; it is like everybody is having an emotional care day with he dogs. She is just lovely. Yeah we will put her in anything.

Though there’s been no word of Brown joining the cast of either film just yet, it’s possible she’s poised to join one or both film, with additional photography planned for Doomsday this spring ahead of principal photography for Secret Wars. However, even as Marvel Studios prepares to end its current saga, work is already underway for the next, which will feature a heavy dose of mutants…and new rumor suggests that Brown may be in line for a key role as a member of the studio’s first team of X-Men.
According to social media scooper My Time To Shine Hello, Marvel is considering casting Brown as one of the core members of the team, though stops short of naming the role.

After several years with little to no movement, Marvel Studios X-Men reboot began to gather some momentum in the Fall of 2023 when Kevin Feige began meeting with writers to discuss pitches for the project. By April 2024, Hunger Games: The Ballad of Songbirds and Snakes writer Michael Leslie had landed the gig and rumors quickly emerged that that the MCU’s first X-Men film would feature two fan-favorite characters as the leads: Kitty Pryde and Gambit.
In May, Thunderbolts* director Jake Schreier signed on to direct what he’s called a “complex” take on the X-Men. With the Russos rumored to be joining the Marvel Studios’ Parliament to help oversee the “Mutant Saga,” could Brown be in the mix for Kitty Pryde, a character Feige has long been rumored to want to have at the center of Marvel’s X-Men stories? She certainly carries a ton of cache with young audiences and, at 21, fits the bill for the studio’s “youth-focused reboot.” Casting on X-Men should get heated up after the New Year–it not even in the next few weeks–so this particular rumor may resolve itself one way or another relatively soon.
