A favorite leading lady of Emil Jannings (with whom she had starred in "Der letzte Mann" and "Varieté") and of the director F.W. Murnau, Delschaft was at one time slated for the role of Lola-Lola in El ángel azul (1930). However, with Murnau's departure to the U.S., Josef von Sternberg ended up taking over the reigns and installed his own protégé, Marlene Dietrich, in the part. Delschaft was actually considered by many to bear similarities to Dietrich in both appearance and manner.
