The MCU’s X-Men are closer than ever, and after the first big character reveal in Spider-Man: Brand New Day and several casting rumors, it looks like the upcoming team of mutants is set to be incredibly young. While this might seem odd to some fans based on the current state of the MCU, it makes perfect sense for the direction of the franchise going forward.
When FOX’s first X-Men movie was released, the cast wasn’t old. However, they definitely weren’t young adults. Hugh Jackman was 31, Famke Janssen was 35, Halle Berry was 33, Patrick Stewart was 60, and Ian McKellen was 61. Only a few of the cast members were below 30, as James Marsden was 26, Rebecca Romijn was 27, and Anna Paquin was 17. Compared to this, Sadie Sink was 24 when Brand New Day was released, and her Jean Grey seems to be even younger than this. The rumored cast of MCU X-Men characters all seem to be in their early-to-mid-20s, and here’s why Marvel is probably doing this.
3) Mutants Only Make Sense In The MCU If They’re Young
In Marvel Comics, mutants are caused by a latent mutation called the X-gene. These genes are activated when a carrier undergoes a moment of extreme emotional distress, often in adolescence, giving the carrier a new phenotypical trait. In the comics, mutants have been around for more than a million years, and they have been popping up all over the Marvel timeline. This clearly isn’t the case for the MCU, as the first confirmed mutant was Kamala in 2022’s Ms. Marvel, followed by Namor in Black Panther: Wakanda Forever, Simon in Wonder Man, and Jean in Spider-Man: Brand New Day.
For whatever reason, mutants seem to just now be popping up, as it seems unresanoable that they would have gone undetected for generations. So, if the MCU is introducing its first generation of mutants, it only makes sense that they’d be young. It’s unlikely that there is a massive population of mutants running around that has had their mutant abilities for decades. While there may be a handful, explaining characters like Magneto or Professor X, the bulk of mutants should just now be getting their mutations, meaning that they need to be young.
2) The X-Men Actors Need To Be Available For A Long Time
Throughout the 2020s, the MCU got some big names to play major characters. Pedro Pascal is one of the most in-demand actors in Hollywood, and he’s now playing Mister Fantastic. Angelina Jolie and Barry Keoghan were in Eternals, Oscar Isaac was in Moon Knight, Yahya Abdul-Mateen II was in Wonder Man, and so on. While this is good for marketing, it isn’t good for multi-project storytelling over a decade or more. These actors are incredibly busy, and it is difficult to get them back for sequels to their own projects, much less cameos in other projects.
In order for the X-Men to be as integrated into the MCU as they need to be, they need to be available for years. The MCU needs actors who they can pull at almost any moment and not have to worry about schedules, and by picking younger actors, Marvel has less to worry about. These cast members have had less time to build demand for themselves, as most of them have become popular based on one or two projects. Sadie Sink’s celebrity comes almost entirely from Stranger Things, and while the show was massive, it’s over. Marvel probably won’t have to worry about every major franchise and popular director attempting to pull Sink away from the MCU in the same way that they do with actors like Pascal, Jolie, and Isaac. Because of this, Jean will probably appear in more MCU projects than Mister Fantastic, Thena, or Moon Knight.
1) The MCU Needs To Appeal To Young People Again
The MCU started 18 years ago, meaning that if someone was 16 when the first Iron Man came out, they’re 34 now. While there was a point where the MCU had a young audience, this isn’t the case anymore. The franchise has failed to bring new fans in, meaning that the fanbase has been dwindling for years now. While some young characters have been introduced, like Kate Bishop and Ms. Marvel, they haven’t been put center-stage in the MCU in a way that appeals to audience members who aren’t already MCU fans. Meanwhile, the MCU characters who have been put center stage are getting old. Anthony Mackie is 47, Chris Hemsworth is 43, Paul Rudd is 57, Pedro Pascal is 51, Benedict Cumberbatch is 50, Mark Ruffalo is 58, and so on. The big draw of Avengers: Doomsday is the return of Chris Evans and Robert Downey Jr., who are 45 and 61 respectively.
The MCU’s Spider-Man movies have drawn a young crowd, and while the iconic status of the superhero is the main reason, the involvement of young actors like Tom Holland and Zendaya is a major factor. So, it makes sense for the MCU to choose Brand New Day, which is guaranteed to have a younger audience, as the place to start introducing the younger X-Men case. Teenagers are fans of Stranger Things, so if Sadie Sink is involved, X-Men immediately becomes more interesting. The same goes for rumored cast members like Kit Connor, Samara Weaving, Charles Melton, and the rest. By making these superheroes young, Marvel is going after an untapped market in order to widen the appeal of the MCU once again.
