Script breakdown

What is script breakdown in film production?

A script breakdown is the process of reading a screenplay scene by scene and tagging every physical element a scene requires — cast, extras, props, wardrobe, vehicles, stunts, special effects, animals. The tagged result is what the schedule, the budget and every department's prep list are built from.

Elements are conventionally colour-coded by category, a convention inherited from marking up a physical script with coloured pencils. The categories matter because each maps to a department that has to source, book or build the thing.

A breakdown is done once and then relied on everywhere, which makes it the highest-leverage document in prep and the most expensive to get wrong. A prop missed at breakdown is discovered on the shooting day, when the only remaining options are expensive.

Page eighth: A page eighth is the standard unit of screenplay length used for scheduling. Every script page is divided into eight equal vertical strips, so a scene measured at 3/8 occupies three of them. Scheduling, day counts and stripboard lengths are all expressed in eighths rather than in pages.
Stripboard: A stripboard is the shooting schedule represented as one coloured strip per scene, ordered in the sequence the production will actually shoot. Each strip carries the scene number, length in eighths, cast IDs, location and day/night. Reordering the strips reorders the shoot.
Scene heading: A scene heading is the capitalised line that opens every scene in a screenplay, stating whether the scene is interior or exterior, where it takes place, and whether it is day or night — for example, INT. EDIT SUITE - NIGHT. It is the line scheduling software parses to build a breakdown.
Breakdown sheet: A breakdown sheet is the one-page record of a single scene's requirements produced during a script breakdown. It carries the scene number, its length in eighths, the location, day or night, a one-line synopsis, and every tagged element grouped by department.
