The title sequence of Se7en uses unsettling music, screams, and a black and white color scheme to generate an eerie, dark, and thrilling tone. Distorted and layered white text on a black background, along with close-ups of mysterious objects like a razor blade, aim to make the viewer feel uneasy and build tension without revealing details. The lack of context and focus on potentially disturbing fragments hints that the film will involve a psychopathic killer and mystery.
