The document discusses four types of title sequences: 1) Discrete title sequences which are separately filmed clips that set the mood before the film through visuals and music. Skyfall is provided as an example. 2) Stylized sequences rely on editing of text and fonts to convey mood. Zombieland is used as an example. 3) Credits over a blank screen use color, sound and minimal text to set the tone. 4) Narrative openings have a character speak directly to the audience to provide context before being introduced in the film.
