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.
Live-action animated film
During the popularity of the silent film in 1920s and 1930s, the popular animated cartoons of Max Fleischer included a series where his cartoon character Koko the Clown interacted with the live world; for example, having a boxing match with a live kitten. In a variation from this and inspired by Fleischer, Walt Disney's first directorial efforts, years before Oswald the Lucky Rabbit was born in 1927 and Mickey Mouse in 1928, were the live-action animated "Alice Comedies" cartoons, in which a young live-action girl named Alice interacted with animated cartoon characters.
