How to break down a script for a shoot
A script breakdown turns a screenplay into a list of everything each scene needs: who is in it, where it happens, day or night, how long it is on the page, and every prop, costume, vehicle and effect it asks for. It is the first job of pre-production after the script is locked, because the schedule, the budget and every department’s shopping list are built from it.
1. Read it once without a pen
Read the script start to finish as a story before you mark anything. You will catch the things a line by line pass misses: a character who is mentioned in scene 4 and only appears in scene 30, a car that has to be the same car across three days, a cut on the clock that means scene 12 is the same night as scene 40.
2. Number the scenes and read the headings
Every scene heading tells you three things you will schedule by: interior or exterior, the place, and the time of day. INT. KITCHEN - NIGHT is a set, a lighting state and a call time. If the script is not numbered yet, number it now and never renumber it: scene 14 has to stay scene 14 on every document from here to the edit. New scenes get letters (14A).
3. Measure each scene in eighths
Scene length is counted in eighths of a page. Fold a page into eight strips: a scene that runs three of them is 3/8, a scene of a page and a half is 1 4/8. It sounds fussy, but it is how an AD estimates the day: a feature often manages three to five pages a day and television more, and the eighths are how you add up a day before you have a shot list.
4. Mark the elements, one colour each
Go through each scene and mark everything a department will have to supply. The common convention, which most ADs learned and most breakdown software copies:
| Element | Mark |
|---|---|
| Cast (speaking parts) | Red |
| Stunts | Orange |
| Extras, silent bits | Yellow |
| Extras, background | Green |
| Special effects | Blue |
| Props | Purple |
| Vehicles and animals | Pink |
| Sound effects and music | Brown |
| Wardrobe | Circled |
| Make-up and hair | Asterisk |
| Special equipment | Boxed |
Productions vary, and what matters is that everyone on yours reads the colours the same way. Mark only what someone has to bring, build or book. “She sits” is not a prop; “she sits on the broken chair” is.
5. One breakdown sheet per scene
Copy each scene’s elements onto a sheet of its own: scene number, heading, pages, a one-line description, then the elements grouped by department. This is the document every head of department reads, and the one the schedule is built from. In a spreadsheet, one row per scene with a column per category does the same job.
6. From breakdown to schedule
With every scene broken down, the AD groups them into shoot days: by location first, because moving a unit is expensive, then by time of day, then by who is in them, because an actor called for one scene on each of five days costs five days. That grouping is the shooting schedule, and each day of it becomes a call sheet. The difference between the two is worth knowing before you start.
Common mistakes
- Breaking down before the script is locked, then doing it again for every draft.
- Missing continuity: the same cut, bruise, or costume across scenes shot weeks apart.
- Counting a scene with no dialogue as short. Action runs long on the day.
- Leaving out the things only implied: a phone that has to ring, rain through a window.
