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:
Steamboat Bill, Jr.
The film inspired the title of Walt Disney's "Steamboat Willie" (1928), which was released six months later and is considered the debut of Mickey Mouse.
