Martin Scorsese establishes key themes and introduces main characters in the openings of his films Casino, Goodfellas, and Raging Bull. Specifically, the openings introduce the protagonist in the first shot through a long shot in Casino, three characters in a car in Goodfellas, and Robert De Niro boxing in slow motion in Raging Bull. Scorsese also uses elements like low-key lighting, diegetic sounds, and titles spaced between objects to set moods of danger, cynicism and establish settings and characters at the start of each film.
