The opening sequence of the thriller Edge of Darkness uses dark tones, isolated houses in the mountains, and quiet ambient music to set a mysterious tone. Fragmented footage is shown, including a childhood video of a little girl playing at the beach. Medium shots introduce floating dead bodies in the water and the girl running on the beach. The sequence cuts between shots of the girl and the protagonist waiting at a train station, establishing the setting and characters through cinematography, sound design, and editing techniques.
