Marvel's Avengers: Secret Wars Rumor - A Major X-Men Movie Villain Might Return

Since Patrick Stewart reprised his role as Professor X in director Sam Raimi's 2022 Disney-Marvel Studios blockbuster "Doctor Strange in the Multiverse of Madness," the floodgates have been flung wide open for members of 20th Century Fox's "X-Men" series to join the Marvel Cinematic Universe.

Also in 2022, of course, Ryan Reynolds announced Hugh Jackman's Wolverine would be the next big X-Men team member to join him in the MCU with the upcoming third "Deadpool" movie. If that weren't enough, rumors surfaced in May 2023 that three original "X-Men" would return with Jackman's Wolverine in "Deadpool 3," with claims that Halle Berry, James Marsden, and Famke Janssen would be reprising Storm, Cyclops, and Jean Grey, respectively.

Now, a rumor has surfaced that a major "X-Men" villain is joining the MCU in Marvel's "Avengers: Secret Wars." In a post on X, formerly known as Twitter, Hollywood Insider @MyTimeToShineH simply stated, "Ian McKellen will return in Avengers: Secret Wars."

McKellen, of course, originated the role of Erik Lehnsherr/Magneto in "X-Men" in 2000 and reprised the role in "X2: X-Men United" in 2003 and "X-Men: The Last Stand" in 2006. After appearing in an uncredited cameo as Magneto in an end credits scene in 2013's "The Wolverine," McKellen made his final appearance as the character in "X-Men: Days of Future Past" in 2014. From there, Michael Fassbender, who played the younger version of the character in 2011's "X-Men: First Class" and "X-Men: Days of Future Past," solely took up the mantle of the villainous mutant for 2016's "X-Men: Apocalypse" and 2019's "X-Men: Dark Phoenix."

McKellen isn't the only X-Men team member rumored to be in Avengers: Secret Wars

The post on X by @MyTimeToShineH didn't offer any more details on Ian McKellen's rumored participation in "Avengers: Secret Wars," so only time will tell whether the role will be a lead or supporting turn, or just a cameo. Whatever the case may be, McKellen doesn't appear to be the only "X-Men" actor to be rumored for the MCU film.

@MyTimeToShineH and fellow Hollywood insider @CanWeGetToast have tweeted some "Marvel: Secret Wars" rumors teasing that Hugh Jackman's Wolverine and two movie Spider-Men could be joining the cast. In an August 2023 tweet, @CanWeGetToast wrote, "Before the strikes, Kevin Feige reached out to Andrew Garfield about having his #SpiderMan appear in #AvengersSecretWars," and in January 2023, @MyTimeToShineH posted, "Yes Tobey Maguire and Hugh Jackman will meet and fight alongside each other in Secret Wars." 

As for any further rumblings of other "X-Men" stars appearing in "Avengers: Secret Wars," James McAvoy is keeping mum about a Professor X appearance in the film. McAvoy, of course, starred as the younger version of Patrick Stewart's Charles Xavier in four "X-Men" films, beginning with "X-Men: First Class," and appeared in an uncredited cameo as the character in "Deadpool 2" in 2018.

There are currently no details about the plot of "Avengers: Secret Wars," which is still in development. The film is currently slated for a May 2027 release.
