1) The documentary uses a variety of filming techniques like non-linear storytelling, shot-reverse-shot editing, and different shot sizes to develop the genre of a sports drama film about boxing. 2) Sound is used both diegetically and non-diegetically to provide context and emotion. This includes voiceover, music, and adjusted sound levels during editing. 3) Mise-en-scene with costumes, locations, and props link the characters to the sport setting and genre of the film. Typography with bold white subtitles and titles are used for dramatic effect and readability.
