[2] Fürth would transition to the era of sound film with ease, and would become a notable character actor throughout the late 1920s and 1930s, appearing in such films as G. W. Pabst's drama Diary of a Lost Girl (1929) opposite American actress Louise Brooks, and Karel Lamač's Die Fledermaus (1931) opposite Czech actress Anny Ondra.
