Fun and Fancy Free
Disney had provided the voice for Mickey Mouse since his debut in 1928, and "Fun and Fancy Free" was the last time he would voice the role regularly, as he no longer had the time or energy to do so. Disney recorded most of Mickey's dialogue in the spring and summer of 1941. Sound effects artist Jimmy MacDonald would become the character's new voice actor, starting in 1948. Disney, however, did reprise the role for the introduction to the original 1955–59 run of "The Mickey Mouse Club".
Mickey Mouse universe
The Mickey Mouse universe is a fictional shared universe which is the setting for stories involving Disney cartoon characters Mickey and Minnie Mouse, Pluto, Goofy, Donald Duck and many other characters. The universe originated from the "Mickey Mouse" animated short films produced by Disney starting in 1928, but its first consistent version was created by Floyd Gottfredson in the "Mickey Mouse" newspaper comic strip. Real-world versions also exist in Disneyland and Tokyo Disneyland, called Mickey's Toontown.
