The document discusses different types of film openings including flashbacks, panning landscapes, narrations, fight/shootout scenes, title sequences, and chase scenes. These different opening techniques are used to entice audiences to continue watching, establish characters and genre, set the scene and time period, quickly describe the story, reveal the tone and protagonists/antagonists, introduce title and cast, and bring audiences right into the action. Examples are given of each type of opening from films like Saving Private Ryan, Open Range, Hot Fuzz, Windtalkers, Catch Me If You Can, and Casino Royale.
