The film industry has been in development. Driven by the continuous upgrading of the film market demand, the requirements for the artistic guidance level of the film are also getting higher and higher. In particular, narrative films should give full play to the role of artistic guidance to ensure that the effect of narrative films can meet the director's wishes and story themes. This study is based on the theoretical basis of artistic guidance and narrative aesthetics in films. By analyzing the role of film art elements in storytelling, this paper summarizes the artistic design in narrative structure and the narrative innovation in artistic orientation, so as to understand the specific role of artistic guidance in film narrative aesthetics.
