In 1929, Dietrich landed her breakthrough role of Lola Lola, a cabaret singer who caused the downfall of a hitherto respectable schoolmaster (played by Emil Jannings), in the UFA production of "The Blue Angel" (1930), shot at Babelsberg film studios. Josef von Sternberg directed the film and thereafter took credit for having "discovered" Dietrich. The film introduced Dietrich's signature song "Falling in Love Again", which she recorded for Electrola and later made further recordings in the 1930s for Polydor and Decca Records.
