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.
Cinema of Germany
The arrival of sound at the very end of the 1920s, produced a final artistic flourish of German film before the collapse of the Weimar Republic in 1933. As early as 1918, three inventors came up with the Tri-Ergon sound-on-film system and tried to introduce it to the industry between 1922 and 1926. UFA showed an interest, but possibly due to financial difficulties, never made a sound film. But in the late 1920s, sound production and distribution were starting to be adopted by the German film industry and by 1932 Germany had 3,800 cinemas equipped to play sound films. The first filmmakers who experimented with the new technology often shot the film in several versions, using several soundtracks in different languages. The film "The Blue angel" (1930), directed by the Austrian Josef von Sternberg and produced by Erich Pommer, was also shot in two versions - German and English, with a different supporting cast in each version. It is considered to be Germany's first "talkie" and will always be remembered as the film that made an international superstar of its lead actress Marlene Dietrich. Other notable early sound films, all from 1931, include Jutzi's adaptation to Alfred Döblin's novel "Berlin Alexanderplatz", Pabst's Bertolt Brecht adaptation "The Threepenny Opera" and Lang's "M," as well as Hochbaum's "Raid in St. Pauli" (1932). Brecht was also one of the creators of the explicitly communist film "Kuhle Wampe" (1932), which was banned soon after its release.
