The upcoming horror-adventure feature The New Mutants is the last vestige of the X-Men movie universe Fox had been developing before being acquired by Disney.
In an interview, Charlie Heaton, who plays Cannonball in the upcoming film, confessed that despite now technically belonging to the same shared universe, he does not see the characters from The New Mutants crossing over into the larger MCU any time soon.
Director of the movie, Josh Boone, also believes the tone and aesthetic of The New Mutants would not gel with other live-action Marvel properties.
It has long been teased that The New Mutants is going to be a full-fledged horror movie rather than an action-adventure saga, so it is easy to understand why Boone and the other would not see their movie fitting in with the more family-friendly vibe of the MCU in general, although the director has previously revealed his plans for a separate The New Mutants franchise with three installments, each with a different take on horror movie tropes.
