1930: The Blue Angel directed by Josef von Sternberg starring Marlene Dietrich in her breakthrough role, premieres in Germany. This was the first of seven feature-film collaborations between Marlene Dietrich and Josef von Sternberg. The director in his autobiography wrote that Dietrich came to test for the film with a bored, world-weary attitude because she was convinced she wasn't going to get the role and was merely going through the motions. It was precisely what he wanted for the character.
