Marlene Dietrich (1901-1992) was the biggest film star Universum-Film AG (UFA) ever produced. The Blue Angel, directed for UFA by Austrian-American director Josef von Sternberg, was the film that started Dietrich's career. Based on Heinrich Mann’s novel Professor Unrat, it was one of the first sound films made in Germany and became an international success. An English-language version was shot simultaneously. Dietrich played a femme fatale, a role in which she would be cast repeatedly. After the success of The Blue Angel, she followed von Sternberg to Hollywood, where she continued her successful career.
