The opening sequence of Jack Reacher establishes the main character as a man of authority through shots of his hands gripping a switch and holding a gun. It shows him in a rural setting and a city, hinting at a clash between the two. Non-diegetic sounds create mystery and suspense around what will unfold and who the main character is. Editing techniques like parallel shots, jump cuts, and action matches are used to build tension and introduce the character. Props like bullets and a machine gun attached to the character convey he is important and dangerous, while his soldier/assassin costume hints at mystery around his authority.
