This work investigates forms of treating politics, which are present in some of the cinematic narratives of a melodramatic nature, produced in Argentina during the first years of the twentieth century. The melodrama typical features, such as the articulation of moral polarizations and strong emotional appeal, together with references to critical events of the internal politics, were persistent in the Argentinean cinema of those years, when the cinematographic production in the country was experiencing a new boom. Common Ground, by Adolfo Aristarain and Moon of Avellaneda, by Juan José Campanella, are two of the key movies that represent that persistence and they are the main focus of this analysis. Firstly, we argue that there is a strong presence of political messages that opposed the expansion of the role of free market in society, which is countered with the embrace of communitarian principles and values. Secondly, we observed a radical restriction of the space for political action Thus, through the melodramatic mode, these narratives articulate a moral associated to political principles in the reduced scale of the local and familiar relations.
