The biggest confirmed addition is Sadie Sink, who made her MCU debut as Jean Grey in Spider-Man: Brand New Day. Her introduction marks the first official appearance of one of Marvel’s most iconic mutants in the MCU and is widely seen as the foundation for the upcoming X-Men reboot.

Marvel has also reportedly cast Samara Weaving as Emma Frost, the powerful telepath and longtime X-Men ally whose complicated history with Charles Xavier’s team has made her one of the franchise’s most popular characters. Multiple trade outlets report that Weaving landed the role after an extensive casting process.

Beyond those names, several actors are rumored to be joining the film. Cailee Spaeny has been linked to Rogue, Charles Melton is rumored to play Beast, Adam Driver has been connected to the villain Mr. Sinister and Tramell Tillman is expected to portray William Metzger, a character already introduced in Spider-Man: Brand New Day.
