Regardless of how true the origin story Mickey mouse Orlando, Florida shirt, Walt and his remaining loyal staff worked separate from the hired-away staff and worked on Mickey after Walt’s return. Ub Iwerks either created Mickey’s design or refined it, depending on the version of the story you hear, and did most of the initial animation for the film’s, at a breakneck pace. The first cartoon created was called Plane Crazy, and it featured Mickey’s attempts to get airborne like his hero Charles Lindbergh. A second cartoon, Galloping Gaucho, was created, but it didn’t seem like there was much interest in this new character.
A third cartoon featuring Mickey mouse Orlando, Florida shirt was in the initial stages of production when The Jazz Singer, the first picture with sound, was released. Walt decided that sound would add something to the cartoons he and his team were creating, and they came up with a soundtrack and wrote music; Walt himself provided Mickey’s voice. Walt and his men went to New York and recorded sound for the film using a bootlegged sound process obtained from a shady producer, and then shopped the completed cartoon.
