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."

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 Ogre (German: Der Unhold ) is a 1996 French-German drama film directed by Volker Schlöndorff and starring John Malkovich, Gottfried John, Marianne Sägebrecht, Volker Spengler, Heino Ferch, Dieter Laser and Armin Mueller-Stahl.
