1930 - Realism
The tradition of Griffith, of Flaherty and of the Russian masters was continued by the Scottish Grierson (Drifters, 1929), creator of the so called British group of documentary cinema, where directors like Cavalcanti, Wright and Watt demonstrated together the possibilities of expression of the sound editing (Night Mail, 1935).
The psychological-realistic drama acquires consistence in the French cinema with producers like Renoir (La Grande Illusion, 1937), Duvivier (Pepe le Moko, 1936) and Camé (Dawn, 1939).
