Cinema represents the human being in various life dynamics, employing a set of techniques that contribute to the final aesthetic of the narrative, hence the use of the term ‘techno-aesthetics.’ Traditionally, the portrayal of mental illnesses in cinema is considered stigmatizing, as it often depicts characters with mental disorders as ‘crazy.’ Therefore, there is a need to examine whether there has been any evolution in how cinema represents psychopathologies. The manner in which techno-aesthetics is used in representing mental illnesses is seen as the primary objective. To achieve this, a sample of films was selected according to a set of criteria and analyzed using a framework that gathers the techno-aesthetic aspects employed and how mental illness is portrayed. Thus, besides determining how depression, anxiety, bipolar disorder, and schizophrenia are represented in technical terms, it also becomes possible to ascertain whether this representation constitutes an advancement in scientific terms.
