There are four main types of film title sequences: discrete, narrative, credits over screen, and heavy stylized editing. A discrete sequence, like in Se7en, acts as a prelude to set the tone before the film begins without fully introducing characters. Narrative sequences tell a small story, like in The Shining where the opening stalks characters driving to imply danger. Heavy stylized editing uses creative effects throughout, as seen in The Taking of Pelham 123 to engage audiences from the start.
