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:
Mighty Mouse
The first seven films starred the character named Super Mouse. In these early films, the character's costume is much closer in design to that of Superman (blue tunic and tights with red trunks and cape). In certain subsequent television airings, the words "Super Mouse" were edited out, and the words "Mighty Mouse" were dubbed in its place.
