What format is used for scene headings in a script?

Scene headings in a script, also referred to as slug lines, are standardized to be written in all capital letters. This formatting convention clearly distinguishes scene headings from the dialogue and action lines that follow, making it easy for the reader to identify where a new scene begins. The capitalization provides visual clarity and adheres to industry-standard practices, which are crucial in the film and television industry where scripts are often read quickly by producers, directors, and crew members. The use of all caps signifies the importance of the scene, indicating both the location and the time of day, which are critical for production. This format helps streamline the reading process and supports effective communication among the various departments involved in film production.
