In many ways, Die Marquise von O... can be viewed as a continuation of the Moral Tales series. Its central plot hinges around a moral dilemma for each of its principal protagonists. First, how can the man who made the Marquise pregnant without her knowing reveal himself without bringing disgrace on both himself and the woman he loves? Second, how is the Marquise to react when she finds herself pregnant with no knowledge of how it could have come about? Rohmer skilfully portrays the anguish that both characters endure as they struggle to make sense of their predicament and navigate a course through the maelstrom of prejudice and accepted conventions of their time. The inevitable happy ending in von Kleist's novel is less certain in Rohmer's film, and Rohmer even goes so far as to introduce elements (such as another possible father for the Marquise's child) to make the outcome less predictable.
The film is a near-faultless piece of Rohmeresque drama, beautifully written and with compelling performances, particularly from Edith Clever and Bruno Ganz. Indeed, the film's overall quality makes it easy to forgive Rohmer his indulgences, such as the display of histrionics from the Marquise's mother and father. Rohmer can himself be glimpsed briefly near the start of the film - he appears as a Russian soldier in one if his very rare film appearances. The film earned Rohmer the Grand Prix spécial du Jury at Cannes in 1976.
