The fictional cinema rarely exhibit to its audience the production process that gives shapeto its discourse. But quite more probable is that carefully get mixed or deleted the traces of what happened, to induce the "voluntary suspension of disbelief", an agreement between producers and audiences of the discourse, of wich depends any satisfacory enjoyment of a fiction. For the cinema industry is more productive to elaborate a mythology covering of the media, rather than to use it to report its operation. The fi rst att itude prevailed during the half century that big studios system lasted. The second att itude, a reported, critic or just narcissistic one, manifested during the next half century, focusing sometimes on biographical aspects of the production process or on media representation system's critic.
