Disney's Steamboat Willie is a landmark in the history of animation. It was the first Mickey Mouse film released and the first cartoon with synchronized sound. It threw silent animation into obsolescence, and launched an empire. Previously, there had been little to distinguish Disney's cartoons from those of his competitors. He was facing bankruptcy when Alan Crosland's The Jazz Singer, with long sequences of song and dialogue, took America by storm in 1927. Sensing that sound movies meant big business, Disney decided to stake all on his talking mouse. The movie opened at the Colony Theater in New York on November 18, 1928, a date that would become known as Mickey's birthday.

Audiences were stunned by the vitality of the film's characters. Unhampered by the difficulties of using new equipment with live actors, Disney was able to fuse technology with handcraftsmanship, naturalism with abstraction, an ability that, over time, proved him to be a great artist. So strong was the audience demand for Steamboat Willie that two weeks after its premiere Disney re-released it at the largest theater in the world, the Roxy in New York City. Critics came to see in Mickey Mouse a blend of Charlie Chaplin in his championing of the underdog, Douglas Fairbanks in his rascally adventurous spirit, and Fred Astaire in his grace and freedom from gravity's laws.
