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:
Thru the Mirror
Thru the Mirror is a Mickey Mouse cartoon short film produced by Walt Disney Productions and released by United Artists in 1936. In this cartoon short, Mickey has a "Through the Looking-Glass"-type dream that he travels through his mirror and enters a topsy-turvy world where everything is alive. While there, he engages in a Fred Astaire dance number with a pair of gloves and a pack of cards, until the cards chase him out of the bizarre world. The title is written as "Thru the Mirror" on the title card, but the alternative spelling Through the Mirror is used on the poster for the film.
