Auteurism is a film theory that emphasizes the director as the primary creative force behind a film, suggesting that their personal style and vision can shape the narrative and aesthetic of the movie. This approach argues that a director's individual influence is akin to that of an author in literature, often leading to a recognizable signature across their body of work. By focusing on the director's role, auteurism elevates their contributions and encourages viewers to analyze films through the lens of the director's personal experiences and themes.
