It is believed that Catholic religion is a key element in Spanish society and that it is present in numerous aspects of everyday life. There is no doubt that religious beliefs are residuals from each culture’s past and history. However, the general public’s opinions on religion have drastically changed after the disappearance of Franco’s political heirs. Production and distribution of new discourses in the democratic era have contributed to this change. These new discourses have been created in response to previous discourses, which extolled a dictatorship that used religion as a tool to expand its political power. Although these democratic discourses are varied, literary and cinematic works play an essential role in this process. The aim of this work is to investigate how novels and movies contribute to the alteration of the citizens’ perceptions of a certain reality. Dulce Chacón’s novel ""The Sleeping Voice"" as well as its movie adaptation will be analyzed, especially taking into account the methods that the writer and the film director apply to create an opposed image of the Church. This prompts further reflection on the aspects, which Francoist discourses had tried to hide. In order to accomplish this research, critical discourse analysis is used as the main methodology.
