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 (film series)
The name "Mickey Mouse" was first used in the films' title sequences to refer specifically to the character, but was used from 1935 to 1953 to refer to the series itself as in "Walt Disney presents a Mickey Mouse." In this sense "a Mickey Mouse" was a shortened form of "a Mickey Mouse sound cartoon" which was used in the earliest films. Films from 1929 to 1935 which were re-released during this time also used this naming convention, but it was not used for the three shorts released between 1983 and 1995 ("Mickey's Christmas Carol", "The Prince and the Pauper", and "Runaway Brain"). Mickey's name was also used occasionally to market other films which were formally part of other series. Examples of this include several "Silly Symphonies", "Don Donald" (1937), and "Goofy and Wilbur" (1939).
"Mickey Mouse" began production in April 1928 after the Disney studio lost the license to Oswald the Lucky Rabbit. The first two films, "Plane Crazy" and "The Gallopin' Gaucho", were previewed in theaters but failed to pick up a distributor. For the third film, Disney added synchronized sound, a technology that was still in its early stages at the time. "Steamboat Willie" debuted in New York in November 1928 and was an instant success. The revenues from the film provided the studio with much needed resources, and the studio quickly began to produce new cartoons as well as releasing sound versions of the first two.
