The tape-recorded narration heard throughout the film (particularly during the final scene) was not scripted. Volker Spengler (playing Elvira Weishaupt) and Rainer Werner Fassbinder recorded the narration together, with Fassbinder asking questions and Spengler responding in character. In the final cut of the film, Fassbinder's voice is edited out.
Richard Linklater's favorite Fassbinder movie.
