The document discusses the use of lighting in the film Fight Club, directed by David Fincher. It notes that Fincher typically uses dark, moody lighting that casts long shadows. In Fight Club, scenes involving the main character's madness or alter ego Tyler are lit more darkly and grittily. The dark lighting of the fight club scenes suggests the unhealthy nature of using violence to solve problems and shows the protagonist descending further into his subconscious. The lighting helps tell the story of a man battling his inner demons through its contrast of bright scenes in the real world and darker scenes involving madness and Tyler.
