The long-awaited 2014 film by Mario Martone on Giacomo Leopardi - Il giovane favoloso (Leopardi, in the English edition) - gives the opportunity to make some critical considerations on the public disclosure of biographical information. At the basis there is the issue of subjectivity. With which instruments or methods should we deal with it? And what are the boundaries of the private life of a person we should not cross? What is "true - and what is "false" in this area? What are the responsibilities of psychoanalysis and of psychological disciplines in general? It is not questioned the usefulness of knowing and disseminating the details of a life, but the way in which this is done, keeping into consideration the laws of communication. Leopardi’s life, as recounted by Martone in this movie, is an example of what really should not be done on the subject of biography.
