Innumerable starring roles in silent movies and early talkies with super-stars Emil Jannings, Marlene Dietrich, and Hans Albers followed.

On 21 February 1927, she created the role of Mascha in the world premiere of Der Zarewitsch by Franz Lehar at the Deutsche Künstler Theater in Berlin, alongside Rita Georg and Richard Tauber, with the composer conducting.

She celebrated her greatest success in 1933 with the role of the record shop assistant Nina in Ein Lied geht um die Welt aka A Song Goes Around the World in which she starred with then popular singer Joseph Schmidt and her mother, Ida Perry.

In 1933, after the Nazis came to power, because she was not reinrassig or pure-blood, it became difficult for Ander to find work.

Her only two Nazi era German films were Wie einst im Mai (1938) and Anton the Last (1939).
