In this article we approach Luis García Berlanga's film Tamaño natural (1973) from the point of view of textual analysis. This film is alien to the director's usual style in many aspects, including the detail about the main character drinking alcohol on several occasions, a fact that is unusual in Berlanga's protagonists. This fondness for alcoholic beverages is in line with the idea put forward by Freud in the "Three Essays for a Sexual Theory" (1905-1915), where the author connects the adult's inclination to drink and smoke with the preservation of the erogenous importance of the labial area, typical of the oral phase. The idea we are trying to put forward is that Tamaño natural is a film in which orality dominates in many ways, but, above all, in the maternal background that permeates the film and directs Michel's relationship with his precious sexual toy.
