Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
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.
