The opening sequence of Se7en, directed by David Fincher, introduces the killer John Doe through disturbing close-up shots and unsettling imagery set to a gritty score. The dark color palette, flashing images, and disorienting editing aim to put viewers on edge and hint at the psychologically thrilling and horrific story to come. Specific techniques like close-ups, unusual mise-en-scene elements, and minimal character shots are analyzed for their ability to build tension and intrigue the target adult audience.
