C'était quoi l'âge d'or du cinéma?<end_of_turn>
<start_of_turn>model
This second period ends with the sudden disappearance of silent cinema, first in the United States, then in Europe. The advent of talking cinema dates from the release in the United States of Alan Crosland's two feature films Don Juan (1926) and The Jazz Singer (1927), which used the Vitaphone disc process, which was still very imperfect. This is why Hollywood ends up preferring to record the sound on the film itself. Adapting theaters to the projection of sound films is very expensive, but revenues double; so the studios did not suffer from the crisis of 1929.
Sound recording during filming imposes all sorts of constraints as humorously demonstrated in the musical Singin' in the Rain (1952), by Stanley Donen (born 1924) and Gene Kelly (1912-1996). Very early on, Ernst Lubitsch, René Clair and Rouben Mamoulian (1897-1987) were among the directors who mastered this new technique; they made original use of it in their respective comedies Parade d'amour (1929), Under the roofs of Paris (1930) and Applause (1930).<end_of_turn><eos>
