Fans have waited years for the Marvel Cinematic Universe to deliver its own X-Men movie, and the film's cast has become even clearer. So far, the MCU has found actors to play icons like Jean Grey, Cyclops, and Emma Frost. Meanwhile, several reported characters have yet to be officially cast in director Jake Schreier's film, now scheduled for release in 2028.
With so many casting rumors swirling around the Internet, it can be frustrating for audiences to keep track of what's true. As the X-Men's cast continues to unfold, fans can read this list of those confirmed and rumored to appear as Earth's Mightiest Mutants in the new X-Men movie.

Jean Grey - Confirmed
With the premiere of Spider-Man: Brand New Day, Sadie Sink officially joined the MCU as the new Jean Grey. The Stranger Things actress took the mantle of the mutant telepath after Famke Janssen and Sophie Turner played her in live-action cinema.
Though Sink's character is set to return in Avengers: Secret Wars, it hasn't been confirmed whether she will also appear in the next X-Men movie. Given Jean's reputation as a core member of the X-Men, chances are that she will be a part of the team in the MCU's upcoming movie. Even Marvel Studios CEO Kevin Feige told Variety that Jean will have "immense significance" in the franchise going forward.

Emma Frost - Confirmed
Ready or Not actress Samara Weaving has officially joined the MCU as the new Emma Frost. Mad Men actress January Jones previously portrayed the telepathic mutant as a villain in X-Men: First Class.
Like in Fox's X-Men films, Emma Frost started out in the comics as a member of the evil Hellfire Club. However, the character's icy heart melted in the comics, and she joined the X-Men as one of its leading figures. It is unclear whether Emma will appear in the MCU movie as a member or an enemy of the X-Men.

Cyclops - Confirmed
Just days after Sadie Sink debuted in Brand New Day, Marvel seems to have found the actor to play her true love and the X-Men's leader in the field. Deadline reported that Marvel is eyeing Heartstopper star Kit Connor to portray Cyclops in the MCU.
Alongside Jean, Cyclops seems set to be a crucial member of the new X-Men. Fans will still see actor James Marsden return as Cyclops at least one more time in Avengers: Doomsday.

Storm - Unconfirmed
Despite appearing in an episode of Marvel's What If...?, the live-action MCU has yet to find its Mistress of the Elements. In an interview with the National Board of Review, Wicked actress Cynthia Erivo expressed interest in playing Storm in the new X-Men movie, describing it as her "dream role."
Erivo's statement all but put her on Kevin Feige's radar. When asked about Erivo's statement in an interview on the Happy Sad Confused podcast, Feige said, "You never know what the future may bring," and that Erivo is a "very good" actor.

Beast - Unconfirmed
So far, actors Kelsey Grammer and Nicholas Hoult have portrayed the bright blue fuzzball in film. Though Grammer will return as Beast in Avengers: Doomsday, it looks like Marvel is looking for someone else to play him afterward. Casting for the new Beast hasn't been confirmed yet, but a couple of prominent names have been dropped so far.
Industry scooper Jeff Sneider previously reported that Marvel is considering Peter Claffey for the role. Claffey became a household name portraying Ser Duncan the Tall in HBO’s A Knight of the Seven Kingdoms. The insider also stated that Beef actor Charles Melton was being considered for the role.

Rogue - Unconfirmed
Rumors about who will play Rogue have brought up a variety of names. These include Sophie Thatcher (Yellowjackets), Margaret Qualley (The Substance), Odessa A'Zion (Marty Supreme), and Cailee Spaeny (Alien: Romulus). Jeff Sneider recently reported that Spaeny is the current frontrunner for the role of Rogue.

Professor X - Unconfirmed
Who are the X-Men without their founder, Professor X? It wouldn't be a surprise if the MCU introduces a new version of Charles Xavier guiding a younger generation of heroes in the new X-Men film. Marvel has not yet revealed who will play the Professor or if he will appear.
Jeff Sneider reported that the studio is looking at Bill Skarsgard (It) and Tom Pelphrey (Task) as potential candidates. Patrick Stewart and James McAvoy previously portrayed Professor X in multiple films, with the former set to reprise the role in Avengers: Doomsday.

Magneto - Unconfirmed
As the X-Men's longest-running adversaries, Magneto appearing in the team's upcoming film seems like a no-brainer. Sir Ian McKellen is set to play Magneto in Avengers: Doomsday, but rumors suggest that Marvel is looking for another actor to take his place after the film.
Scooper ApocHorseman initially stated that Star Wars actor Adam Driver will trade in his lightsaber for a role as the Master of Magnetism. The former has since announced that this statement is incorrect, but that Driver would play a different villain in the MCU.

Mystique - Unconfirmed
It hasn't been confirmed whether Mystique will be a part of the MCU's X-Men movie. However, after meeting with director Jake Schreier about a potential role, Obsession star Inde Navarrette expressed interest in portraying the shapeshifting Mystique in the movie. It is unclear whether Navarrette has been officially cast in the film.
While Mystique has been one of the X-Men's iconic villains, she has been portrayed as an antihero on film by Jennifer Lawrence, who inherited the role from Rebecca Romijn. The latter is set to appear as Mystique in Avengers: Doomsday.

Mr. Sinister - Unconfirmed
Despite being one of the X-Men's most iconic adversaries, Mr. Sinister has yet to make his live-action debut after years of on-and-off plans for an appearance in Fox's film franchise. Rumors have circulated that Mr. Sinister will be a core villain in the MCU's Mutants Era.
Oscar-nominated actor Wagner Moura (The Secret Agent) expressed interest in playing the character in the upcoming X-Men movie, according to Screen Rant. In addition, ApocHorseman claimed that Adam Driver will play Sinister instead of Magneto.
