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".
Golden age of American animation
In the Mickey Mouse series, he continued to add personality to his characters; this resulted in the creation of new characters such as Pluto with The Chain Gang in 1930, Goofy with Mickey's Revue in 1932 and Donald Duck in 1934 with "The Wise Little Hen" (under the "Silly Symphony" series). When Disney's contract with Technicolor expired, the Mickey Mouse series was moved into Technicolor starting with The Band Concert in 1935. In addition, Mickey was partially redesigned for Technicolor later that year.
