The opening scene of Jaws effectively establishes the tone and sets expectations for the film. It introduces the ominous Jaws theme and shows teenagers partying near the water late at night. Two characters wander off and the camera suggests something unseen lurks beneath the surface. As a girl swims alone, shots mimic a predator's point of view, building tension until she is attacked just off screen. Alternating frantic shots of her struggle with calm shots of a sleeping boy on the beach hints he may rescue her while ratcheting up suspense. The director crafts an unsettling atmosphere through camerawork, music, and editing that foreshadows danger and draws the audience in.
