David Fincher's film Fight Club effectively demonstrates auteur theory through Fincher's signature directorial style. Fincher uses consistent elements like muted color palettes, deliberate camera shots that guide the audience's gaze, and unconventional character introductions. The film also reflects Fincher's artistic vision through its unreliable first-person narration and fractured narrative structure. Analyzing Fight Club through the lens of auteur theory highlights how Fincher exerts authorial control over his work and influences audiences through his distinctive cinematic techniques.
