Third part of director Christian Petzold's "Gespenster" trilogy. The other two parts are Die innere Sicherheit (2000) and Gespenster (2005).
Film title was inspired by Yella Rottländer, female lead in Wim Wenders' Alice in den Städten (1974).
The plot and conflicts are nearly identical to Herk Harvey's Tanz der toten Seelen (1962). Only the setting, context and some characters are different. The original screenplay by John Clifford is not credited as a source.
