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".

Disney then searched for a replacement among the remaining staff of the Studio. He selected Floyd Gottfredson, a recently hired employee. At the time Gottfredson was reportedly eager to work in animation and somewhat reluctant to accept his new assignment. Disney had to assure him the assignment was only temporary and that he would eventually return to animation. Gottfredson accepted and ended up holding this "temporary" assignment from May 5, 1930, to November 15, 1975.
