Five years after the landmark deal to return the rights to all X-Men characters to Marvel, Disney is finally ready to bring mutants to the forefront of the Marvel Cinematic Universe (MCU). Since the universally panned New Mutants placed the final nail in 20th Century Fox's X-Men universe coffin, fans have been eagerly awaiting new material under the Disney Umbrella. Although Marvel has subtly hinted at including mutants in the MCU, 2024 will mark the first year of new material under the Disney umbrella with the release of a new animated version of X-Men 97 and the third installment in the Deadpool Franchise.
Despite helping to pave the way for the superhero genre, before the MCU was a thought, many of Fox's installments failed to meet audience expectations. Whether it was finding fault with storylines and casting decisions, or backstage drama with directors, Fox just could not find a steady streak with its movies. Even in the final film, New Mutants, poor reception was caused by various factors, including its troubled production, multiple delays, and lackluster execution of the storyline (New Mutant's Controversy).
Since regaining the rights to the property, Marvel has been set on establishing its own separate universe from Fox's previous films, while also allowing former actors to reprise roles. Read more here.
