Mickey Mouse
Audiences at the time of "Steamboat Willie"'s release were reportedly impressed by the use of sound for comedic purposes. Sound films or "talkies" were still considered innovative. The first feature-length movie with dialogue sequences, "The Jazz Singer" starring Al Jolson, was released on October 6, 1927. Within a year of its success, most United States movie theaters had installed sound film equipment. Walt Disney apparently intended to take advantage of this new trend and, arguably, managed to succeed. Most other cartoon studios were still producing silent products and so were unable to effectively act as competition to Disney. As a result, Mickey would soon become the most prominent animated character of the time. Walt Disney soon worked on adding sound to both "Plane Crazy" and "The Gallopin' Gaucho" (which had originally been silent releases) and their new release added to Mickey's success and popularity. A fourth Mickey short, "The Barn Dance", was also put into production; however, Mickey does not actually speak until "The Karnival Kid" in 1929 when his first spoken words were "Hot dogs, Hot dogs!" After "Steamboat Willie" was released, Mickey became a close competitor to Felix the Cat, and his popularity would grow as he was continuously featured in sound cartoons. By 1929, Felix would lose popularity among theater audiences, and Pat Sullivan decided to produce all future Felix cartoons in sound as a result. Unfortunately, audiences did not respond well to Felix's transition to sound and by 1930, Felix had faded from the screen.
Sound film
The first sound feature film to receive near-universal critical approbation was "Der Blaue Engel" ("The Blue Angel"); premiering on April 1, 1930, it was directed by Josef von Sternberg in both German and English versions for Berlin's UFA studio. The first American talkie to be widely honored was "All Quiet on the Western Front", directed by Lewis Milestone, which premiered April 21. The other internationally acclaimed sound drama of the year was "Westfront 1918", directed by G. W. Pabst for Nero-Film of Berlin. Historian Anton Kaes points to it as an example of "the new verisimilitude [that] rendered silent cinema's former emphasis on the hypnotic gaze and the symbolism of light and shadow, as well as its preference for allegorical characters, anachronistic." Cultural historians consider the French "L'Âge d'Or", directed by Luis Buñuel, which appeared late in 1930, to be of great aesthetic import; at the time, its erotic, blasphemous, anti-bourgeois content caused a scandal. Swiftly banned by Paris police chief Jean Chiappe, it was unavailable for fifty years. The earliest sound movie now acknowledged by most film historians as a masterpiece is Nero-Film's "M", directed by Fritz Lang, which premiered May 11, 1931. As described by Roger Ebert, "Many early talkies felt they had to talk all the time, but Lang allows his camera to prowl through the streets and dives, providing a rat's-eye view."
"Talking film is as little needed as a singing book." Such was the blunt proclamation of critic Viktor Shklovsky, one of the leaders of the Russian formalist movement, in 1927. While some regarded sound as irreconcilable with film art, others saw it as opening a new field of creative opportunity. The following year, a group of Soviet filmmakers, including Sergei Eisenstein, proclaimed that the use of image and sound in juxtaposition, the so-called contrapuntal method, would raise the cinema to "...unprecedented power and cultural height. Such a method for constructing the sound-film will not confine it to a national market, as must happen with the photographing of plays, but will give a greater possibility than ever before for the circulation throughout the world of a filmically expressed idea." So far as one segment of the audience was concerned, however, the introduction of sound brought a virtual end to such circulation: Elizabeth C. Hamilton writes, "Silent films offered people who were deaf a rare opportunity to participate in a public discourse, cinema, on equal terms with hearing people. The emergence of sound film effectively separated deaf from hearing audience members once again."
