Sound/Music

Sound are used in the opening scene to help the viewer feel as though they are in the scene. This adds tension and unease for the viewer, because the director tries to put the viewer in the same situation as the characters. The first sound effect we hear is the electric buzz, before we even get a shot of the characters.This is done because it puts the viewer straight into the action, making the emotions and experiences had by the characters are felt more by the audience. After that, we also hear the noise of the gun cocking. This adds to the foreshadowing of the scene, because the gun is so pronounced, one may presume that it will be used for a bad thing (which it is).
