The opening sequence uses dark, dramatic sound effects that build suspense. The first shot shows waves crashing against rocks, setting the scene near water. Cinematography does not immediately show characters' faces, instead showing a character being pounded by water, creating tension. Lighting is used to make one character conversing in a room seem more mysterious and villainous. Shot structures like over-the-shoulder shots and dialogue keep the audience engaged in the story as it unfolds while also withholding full views of characters, building more suspense. A clock counting down seconds at the end leaves the audience as confused as the characters about what will happen next.
