Quick Verdict

Learn the essential process of breaking down a script for scheduling and budgeting, from scene numbering to element identification.

When scheduling a project, the first thing that happens is the numbering of the script. This means assigning numbers to each scene in the script to determine how long the scene is and where and when it takes place. Scene numbers are an essential way to ensure that everyone on the project is working from the same information.

Numbering the Script

Without scene numbers, the only reference cast and crew would have to what is shooting is a page number, and that would not be specific enough. New scenes are usually delineated by slug lines—one line that describes the scene’s location and time of day. Sometimes, when reading a script, the action will move to another location, room, or set, and it is part of the numbering process to determine if a new slug line (and thus a new scene number) is needed.

Calculating Page Counts

Once the numbering of the scenes is completed, the script is broken down further to determine the page count for each scene. The length of the scenes is calculated and broken into 8ths of a page. A scene may be 1/8th of a page, 2/8ths, or more. Generally, each 1/8th of a page equals approximately 1 inch. If a scene is less than an inch, it is still counted as 1/8th of a page. Full pages are counted simply as 1, 2, 3, and so on.

The Breakdown Sheet

The breakdown sheet is used to collect and define the details of each scene to ensure that all details known at this early stage are included for scheduling and budgeting purposes. It is a living document that allows for other documents to be generated and ensures that nothing falls through the cracks.

Key elements identified in a breakdown sheet include:

  • Cast: Which characters appear in the scene.
  • Background Actors: A guess at the number of extras needed.
  • Props: Specific items required for the action.
  • Vehicles / Animals: Any special requirements called out in the script.
  • Special Effects / Wardrobe / Makeup: Anything that affects the budget or prep time.
  • Notes: Information such as whether a scene is intercut with another.

Color-Coding for Clarity

Digital tools and traditional paper breakdowns use color-coding to delineate whether a scene is being shot interior or exterior and if it is day or night. The standard color breakdown for strips is:

  • White: Daytime interiors
  • Yellow: Daytime exteriors
  • Blue: Exterior night
  • Green: Interior night

Every word in a script has meaning and potential ramifications to the schedule and to the budget. Understanding these details early allows for a more accurate plan and better financial management throughout the production.
