Marlene Dietrich shot at Babelsberg film studios. Josef von Sternberg directed the film and thereafter took credit for having "discovered" Dietrich. The film is also noteworthy for having 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. In 1930, on the strength of "The Blue Angel's" international success, and with encouragement and promotion from Josef von Sternberg, who was already established in Hollywood, Dietrich moved to the United States under contract to Paramount Pictures, the US film distributor of "The Blue Angel". The studio sought
Marlene Dietrich in the German city of Belsen throughout the war years, running a cinema frequented by Nazi officers and officials who oversaw the Bergen-Belsen concentration camp. Dietrich's mother remained in Berlin during the war; her husband moved to a ranch in the San Fernando Valley of California. Dietrich vouched on behalf of her sister and her sister's husband, sheltering them from possible prosecution as Nazi collaborators. Dietrich would later omit the existence of her sister and her sister's son from all accounts of her life, completely disowning them and claiming to be an only child. Dietrich received the Medal of Freedom
