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
In 1930, Disney began a newspaper strip called "Mickey Mouse" which greatly expanded Mickey's world which was already well-known from the animated cartoons. The stories then became a work of collaborative fiction with different writers working in different mediums. This sometimes caused continuity discrepancies. For example, while Mickey and his friends largely live in the same contemporary setting, they sometimes appear in exotic settings including period pieces ("Brave Little Tailor", "The Nifty Nineties") and fantasy films ("Fantasia", "Fun and Fancy Free").
