The document discusses conventions for opening credits sequences in films. Typically, opening credits list the major actors and crew in order of appearance or importance, including the production company, director, producer, executive producer, and top billing actors. The credits are usually superimposed over a blank screen or static image and may or may not include accompanying music. Sometimes a brief scene or teaser precedes the credits to set the scene for the film. Cinematography and sound are also important elements that can foreshadow the theme and atmosphere of the film.
