Mickey Mouse
Created as a replacement for a prior Disney character, Oswald the Lucky Rabbit, Mickey first appeared in the short "Plane Crazy", debuting publicly in the short film "Steamboat Willie" (1928), one of the first sound cartoons. He went on to appear in over 130 films, including "The Band Concert" (1935), "Brave Little Tailor" (1938), and "Fantasia" (1940). Mickey appeared primarily in short films, but also occasionally in feature-length films. Ten of Mickey's cartoons were nominated for the Academy Award for Best Animated Short Film, one of which, "Lend a Paw", won the award in 1942. In 1978, Mickey became the first cartoon character to have a star on the Hollywood Walk of Fame.
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.
