The opening sequence of the film SE7EN uses montage editing of close-up shots to set an unsettling and suspenseful tone. Elements like a sinister musical score, the color red, and sounds of screaming immerse the viewer in the thriller/horror genre. Specific shots focusing on things like a razor blade, notes, and religious symbols provide clues about the serial killer's personality and motivations while avoiding revealing too much of the plot. The sequence introduces actor Morgan Freeman as a main character and draws in his existing fans.
