Marianne and Juliane: Marianne and Juliane (German: Die bleierne Zeit ; lit.  "The Leaden Time" or "Leaden Times"), also called The German Sisters in the United Kingdom, is a 1981 West German film directed by Margarethe von Trotta.  The screenplay is a fictionalized account of the true lives of Christiane and Gudrun Ensslin.  Gudrun, a member of The Red Army Faction, was found dead in her prison cell in Stammheim in 1977.  In the film, Von Trotta depicts the two sisters Juliane (Christine) and Marianne (Gudrun) through their friendship and journey to understanding each other.  "Marianne and Juliane" was von Trotta's third film and solidified her position as a director of the New German Cinema.

Barbara Sukowa: Barbara Sukowa (born 2 February 1950) is a German theatre and film actress.  She is known for her work with directors Rainer Werner Fassbinder and Margarethe von Trotta.

New German Cinema: New German Cinema (German: "Neuer Deutscher Film" ) is a period in German cinema which lasted from the late 1960s into the 1980s.  It saw the emergence of a new generation of directors.  Working with low budgets, and influenced by the French New Wave, such directors as Rainer Werner Fassbinder, Werner Herzog, Alexander Kluge, Harun Farocki, Volker Schlöndorff, Helma Sanders-Brahms, Hans-Jürgen Syberberg, Margarethe von Trotta and Wim Wenders made names for themselves and produced a number of 'small' motion pictures that caught the attention of art house audiences, and enabled these directors (particularly Wenders and Schlöndorff) to create better-financed productions which were backed by the big US studios.  However, most of the films were commercial failures and, by 1977, 80% of a budget for a typical German film was ensured by a subsidy.

The Lost Honour of Katharina Blum (film): The Lost Honour of Katharina Blum, or: How violence develops and where it can lead (German original title: "Die verlorene Ehre der Katharina Blum oder: Wie Gewalt entstehen und wohin sie führen kann") is a 1975 film adaptation of the novel of the same name by Heinrich Böll, written for the screen by Volker Schlöndorff and Margarethe von Trotta.

For her performance in this film Carla Gravina was awarded Best Actress at the 1993 Montreal World Film Festival and won the Italian Golden Globe for Best Actress.

Margarethe von Trotta: Margarethe von Trotta (born 21 February 1942) is a German film director who has been referred to as a "leading force" of the New German Cinema movement.  Von Trotta boasts an impressive body of work that has won her awards all over the world in the last forty years.  She was married to and collaborated with director Volker Schlöndorff.  Although they made a successful team, von Trotta felt she was seen as secondary to Schlöndorff.  Subsequently, she established a solo career for herself and became "Germany’s foremost female film director, who has offered the most sustained and successful female variant of "Autorenkino" in postwar German film history."  Certain aspects of von Trotta’s work have been compared to Ingmar Bergman’s features from the 1960s and 1970s.  She says that it was thanks to Bergman's films that she "‘fell in love’ with the medium and its possibilities for representing inner psychic worlds."
