This article assesses the intimate shift that documentary film has experienced in the last decades in Spain. The aim is to identify the aesthetic and narrative strategies that characterize the first-person documentary, as well as its implementation difficulties in Spain due to the socio-historical value associated with the genre. As a case study, the film Mapa (Siminiani, 2012) is analyzed as a practice where the cinematographic and the life of the author are inextricably linked. This is intended to shed light on the generic ambiguity of the film, between the road movie, the filmed diary and auto-fiction.
