Eva Mattes, who is playing Brigitte Mira in this movie, was also performing in a few movies by Rainer Werner Fassbinder back in the 1970s, including In a Year with 13 Moons (1978), Effi Briest (1974) and The Bitter Tears of Petra von Kant (1972).
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 The Merchant of Four Seasons (1972)). Furthermore it is mentioned that she is a vegetarian.
Rainer Werner Fassbinder is mentioning the name of Jean-Luc Godard several times. Godard was one of the main influences of Fassbinder's work.
Director Oskar Roehler said that Love Is Colder Than Death (1969) is his favorite of Rainer Werner Fassbinder's movies.
Katja Riemann and Oliver Masucci were both starring in Herrliche Zeiten (2018), also directed by Oskar Roehler.
Oliver Masucci was 52 when he starred in this film, which makes him 15 years older than Rainer Werner Fassbinder himself, who died at the age of 37.
