Resumen: Linking communication and leadership involves analyzing the relationship of the basic information functions and the influence of the leader to see the relationship between the structure of his / her discourse (theme / focus) and the dynamising action of the latter through their roles. The speech emphasizes dynamic expressions that guide the influence of the leader with his followers. Seeing this relation is the central axis of the contribution of this work where the focus (basic computer function) engages the direction of the action of the leader through concrete roles that define the style of leadership and influence. Cinema has provided us with communicative tools that allow us to analyze the discursive particularities of issuers with a specific linguistic profile. In this sense, certain roles, such as the leader, organize and situate the basic information functions of Topic and Focus so that the character of the latter determines the dynamic style of that role.
