: In this paper we will present the story of one issue that dominated film theory during the silent-film paradigm; one that continues in force even today, that is: the controversy of cinema as an art, based on the “medium specificity” thesis. The exposition of this framework will also serve us, in turn, to present several central notions of film theory, wich were constructed throughout this debate, as well as to point out its main authors and the implications of all kinds –aesthetic, epistemological and cultural– , involved in this topic. By means of this exposition, we aspire to detail a perspective capable of broadening our understanding of the history of cinema, summarizing the fundamental keys that constituted both our attitude as spectators and the relation we currently have with film productions.
