As a narratological concept which developed from literary studies in the sixties, unreliability manifests itself as an idea of difficult theoretical delimitation, finding in a medium such as cinema particularities that complicate its understanding even more. In light of this, the analysis of the present filmic object is preceded by a theoretical review of the concept of unreliability and by an investigation of cinema as a narrative activity. By bringing studies of authors such as Wayne Booth, Seymour Chatman, and David Bordwell, this article establishes a theoretical basis that, despite its heterogeneity, enables a better understanding of unreliable narration in this particular film. The analysis allows one to comprehend unreliable narration as a mechanism that entails complexities regarding the plot and the characters, working with contradictory narrative layers and demanding active participation from the spectator in the comprehension of the story.
