Despite Kevin Feige assuring fans that an X-Men reboot was in development shortly after Disney acquired 20th Century Fox's assets back in 2019, we haven't had a single official update since, with zero mention of the mutant super-team at San Diego Comic-Con over the weekend.
Recently, a rumor did the rounds that contractual issues are preventing Marvel Studios from introducing new actors as established mutant characters such as Wolverine, Cyclops, Storm, etc to The MCU. Now, some more details have come to light, and it sounds like this situation may be more complicated than we first realized.
According to The Illuminerdi, the studio's main concern isn't necessarily the actors who were involved with the previous X-Men movies, but the producers. Apparently, if they wanted to reboot the team using any of the same characters from Fox's franchise before 2025, the likes of Simon Kinberg, Bryan Singer and co. would be, at minimum, entitled to credits and compensation, and may even have some degree of creative control as well.
We're not sure we're fully buying this, but it would explain why there's been radio silence on all things X-Men since 2019, and why the only established mutant character we've seen in The MCU since is Professor Xavier in Doctor Strange in the Multiverse of Madness... with Sir Patrick Stewart reprising the role.
Of course, even if this report is accurate, it wouldn't prohibit Marvel from debuting new mutant heroes and villains with no connection to the earlier films (Kamala Khan was retconned as a mutant in the recent season finale of Ms. Marvel, for example).
Fans are hoping for an announcement at Disney's D23 this September, so, depending on what we learn during the expo, we should have a better idea of where things stand with The X-Men in The MCU fairly soon.
