The opening scene of Jurassic Park establishes tension through its title colors of red and orange, dark lighting, and mysterious sounds coming from behind the trees. As the scene progresses, the lighting brightens to focus attention on a moving box in the trees, making the audience wonder what is inside. Special effects like aggressive dinosaur sounds and workers carrying tasers further suggest danger. In Jaws, the opening scene uses relaxing orange campfire lighting but this also connotes danger. When a girl enters the water, tense music plays to increase the heart rate of viewers. Both films employ a variety of techniques in the opening scenes to engage audiences and set the tone for threats present in the story without revealing full details.
