 Even before Josef von Sternberg's "The Blue Angel" was released to international acclaim in spring of 1930, Paramount Pictures took a keen interest in its new star, Marlene Dietrich.When the Berlin production was completed in January, Sternberg departed Germany before its premiere on April 1, confident that his work would be a success.Legend has it that Dietrich included a copy of author Benno Vigny's story "Amy Jolly" in a going-away gift package when he sailed for America.
