Marvel Studios has announced the cast of the highly-anticipated superhero blockbuster Avengers: Doomsday in a livestream today, confirming the return of familiar faces from past MCU movies, the main cast of the upcoming The Fantastic Four: First Steps, and more interestingly, several stars from Fox's X-Men films, presumably as their original mutant characters.
Kelsey Grammer was the first X-Men actor confirmed to reprise his role. He will presumably return as Dr. Hank McCoy, a.k.a. Beast. Patrick Stewart, who was famous for playing Charles Xavier / Professor X, was announced after him, followed by Ian McKellen, who will presumably reprise his role as Max Eisenhart / Magneto. This announcement should excite X-Men fans who want to see Stewart and McKellen reunite as longtime mutant rivals.
The next X-Men actor announced was Alan Cumming, who made his debut as Nightcrawler/Kurt Wagner; Rebecca Romijn, who played Mystique / Raven Darkholme, was announced next. James Marsden was also confirmed to appear, and he's expected to reprise his role as Cyclops / Scott Summers. Finally, it was revealed that Channing Tatum, who appeared as Gambit / Remy Étienne LeBeau in last year's Deadpool & Wolverine, will star in the next Avengers film.
So, as you can see, there are actors from Fox's original X-Men film trilogy, and the 2011 reboot/prequel, X-Men: First Class. Both Grammer and Stewart reprised their roles in the MCU's The Marvels and Doctor Strange in the Multiverse. Production just started for Avengers: Doomsday, so at this point, their narrative role in the story centered on the conflict against Doctor Doom (Robert Downey Jr.) still remains a mystery.
X-Men Actors in Avengers: Endgame
To sum it up, here's the list of X-Men actors officially confirmed to return in Avengers: Doomsday, though as I previously stated, they are presumably expected to reprise their mutant roles but the announcement hasn't officially confirmed which characters they're playing in the fifth Avengers film.
Kelsey Grammer as Beast
Patrick Stewart as Professor X
Ian McKellen as Magneto
Alan Cumming as Nightcrawler
Rebecca Romijn as Mystique
James Marsden as Cyclops
Channing Tatum as Gambit
Hopefully, there will be surprise appearances of actors not listed here, but at this point, it's still too early to speculate who will return.
