Screenplay format first element: master headings. What is a master scene heading? In screenplay format, a master scene heading, also called primary slug line, is a one line of text in a screenplay that comes before the description of a scene. It gives a context for the whole scene.
Where the scene heading prefix âINT.â or âEXT.â is concerned, standard. screenplay format calls for only one space, not two, after the period. When a scene is immediately followed by action that takes place in the same. location, but later in the day, a new scene heading is needed.
