The aim of this study is to understand the film Melancholia, written and directed by Lars von Trier, from the viewpoint of decadence. This film revolves around the stories of two sisters, Justine and Claire, who, for various reasons, experience extreme melancholy. Although Justine and Claire appear in different forms, the causes of their melancholy are, from the perspective of decadence, interpreted as one: the loss of nature. Both are seen as one because they are in fact paralyzed and their inner nature is dead. Their movements are both determined by external factors. For them, they have nothing to do except waiting for the catastrophe of melancholia.
