The document discusses conventions used in the opening of the author's thriller media product. It begins in a bleak wooded area to set a mysterious tone, referencing other films. An abandoned house creates a sense of entrapment for the protagonist through claustrophobic space and dirty surroundings. Chiaroscuro lighting is used to represent the contrast between innocence and criminality. The title "Rebecca" pays homage to the 1940 film and is shown before action to not interrupt it. Simple white titles and a heavy breathing sound bridge create tension. The opening ends on a cliffhanger to encourage audience attention, a convention of thriller genres.
