After years of speculation and a few dips into the multiverse, the MCU world of the Avengers is finally fully crossing over with the mutants of the X-Men. But while many fans have expected several popular X-Men characters to be fully rebooted and recast, the big reveal for Avengers: Doomsday is that it appears the MCU will fully crossover not with new X-Men actors, but with very famous, and very beloved X-Men actors.
In the ongoing cast-reveal livestream, Marvel confirmed that several legacy X-Men actors including Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, James Marsden, and Rebecca Romijn are all part of the cast of Avengers: Doomsday, indicating that the characters of Hank “Beast” McCoy, Professor Charles Xavier, Magneto, Nightcrawler, Cyclops and Mystique will appear in the MCU proper. Interestingly, Channing Tatum, who never appeared in the original Fox X-Men films, was also confirmed to be in the film, after making his debut as Gambit — in a meta joke about his never-made movie — in Deadpool & Wolverine.
