Classical Hollywood cinema
The beginning of the sound era itself is ambiguously defined. To some, it began with "The Jazz Singer", which was released in 1927 and increased box-office profits for films, as sound was introduced to feature films. To others, the era began in 1929, when the silent age had definitively ended. Most Hollywood pictures from the late 1920s to 1960s adhered closely to a genre—Western, slapstick comedy, musical, animated cartoon, and biopic (biographical picture)—and the same creative teams often worked on films made by the same studio. For instance, Cedric Gibbons and Herbert Stothart always worked on MGM films; Alfred Newman worked at Twentieth Century Fox for twenty years; Cecil B. DeMille's films were almost all made at Paramount Pictures; and director Henry King's films were mostly made for Twentieth Century Fox. Similarly, actors were mostly contract players. Film historians and critics note that it took about a decade for films to adapt to sound and return to the level of artistic quality of the silents, which it did in the late 1930s.
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.
