Mickey Mouse universe
In "Plane Crazy" (1929), the first produced Mickey Mouse story, Mickey is seen at a farm. In all of his early films Mickey is in a rural setting, but most commonly at a farm. This setting was succinctly presented in the first sentences of one of Mickey's first storybooks:
Walt Before Mickey
On the train back to Los Angeles, Walt is inspired to create a new character which he owns the rights to. He and Iwerks subsequently create Mickey Mouse. In 1928, Mickey's first short "Plane Crazy" is screened, and met with a round of applause. Walt, Roy, and Iwerks exit the theatre in celebration, Walt spotting the mouse from the Laugh-O-Gram Studio, reminding him of how far he has come. Insertions during the end credits detail the success Walt, Roy, Iwerks, and the other animators would go on to have in their own careers.
