The opening sequence of a film introduces the audience to the main characters, sets the scene and establishes the mood through music. It captures the audience's attention and allows them to get a sense of the genre and central conflict or problem within the first few minutes. Setting the scene provides clues about where the main story will take place, while introducing characters helps the audience identify with and relate to the protagonist and antagonist. Establishing the central problem or 'equilibrium' gives the audience a glimpse of what will drive the narrative forward. Music plays an important role in reinforcing the mood and evoking emotions from the audience.
