受到德国先锋纪录片《柏林城市交响乐》的启发，由两位青年导演拍摄的《圣保罗都市交响乐》是巴西影史上的经典纪录片。 During the 1920s and the 1930s, the German Walter Benjamin wrote about cities. He was born in Berlin, but felt in love with Paris. In 1927, Walter Ruttmann directed the fantastic "Berlin: Die Sinfonie der Großstadt". Surprisingly, Brazil was tuned with Europe and was the unique country in Latin America that produced modern movies about and influenced by the metropolis. In 1926, it was released a documentary about Recife. In 1928, Humberto Mauro directed his "Sinfonia de Cataguases", ("Symphony of Cataguases") a short inspired in "Berlin: Die Sinfonie der Großstadt". In Porto Alegre, it was produced "A Princesinha do Sul". "São Paulo, Sinfonia da Metrópole", directed by the Hungarian Adalberto Kemeny and Rudolf Rex Lustig, is the most famous and important Brazilian documentary totally inspired in the German classic. The film begins with the dawn, with the city "waking-up", ending in the sunset, showing the dynamics of a big city and its dwellers.
