Eva Mattes, who plays Brigitte Mira in this movie, also performed in a few movies by Rainer Werner Fassbinder back in the 1970s, including In einem Jahr mit 13 Monden (1978), Fontane Effi Briest (1974), and Die bitteren Tränen der Petra von Kant (1972).
Oliver Masucci was 52 when he starred in this film, which makes him 15 years older than Rainer Werner Fassbinder himself, who died at 37.
Britta is based on Irm Hermann, who was Fassbinder's agent and also had a relationship with him. Like in the movie she screamed "Now I know whom you are cheating on me with" after seeing Fassbinder and Kurt Raab together. She also won an award for the best female lead in the 1970s (in this case for Händler der vier Jahreszeiten (1972)). Furthermore it is mentioned that she is a vegetarian.
The opening credits of the movie are shown in different positions and in front of different colors, which is imitating the style of the opening credits from different Rainer-Werner-Fassbinder-movies, including Die bitteren Tränen der Petra von Kant (1972).
Director Oskar Roehler said that Liebe ist kälter als der Tod (1969) is his favorite of Rainer Werner Fassbinder's movies.
