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".
Hazel Sewell
After losing Oswald, Disney created the idea for a cartoon character known as Mickey Mouse. The first Mickey Mouse cartoon was created by a small group of Disney employees. Sewell, Bounds, and Edna Disney were responsible for inking and painting the cels used for the first Mickey Mouse cartoon ever created. The cartoon was titled "Plane Crazy" and it was released in 1928. While "Plane Crazy" struggled to achieve success, the creation of Mickey Mouse led to the release of more cartoons, such as "Steamboat Willie", that performed successfully.
