In 1975 Dagmar Koller, the most photographed woman in Austria, appeared on stage together with Zarah Leander in “Das Lächeln einer Sommernacht“ (The smile of a summer’s night). The world premiere of the musical, which was originally a movie with Ingrid Bergman in 1955, marked the end of Zarah Leander’s career, while Dagmar Koller’s career was just beginning to take off.
