The document discusses codes and conventions commonly used in film openings. It describes how film openings are typically designed to grab audience attention and provide context about the genre. There are two main narrative codes - the "action code" where events unfold linearly, building tension, and the "enigma code" where the audience is thrown into a mystery without context. Film openings also establish genre through visual cues like costumes, lighting and settings. Production company logos, character introductions through voiceovers, unique typography and genre-appropriate music are other common elements discussed.
