Revision Slugline

An updated scene heading indicating revisions to script pages.


Overview

A revision slugline replaces the original scene heading on a revised script page to reflect changes in location, time of day, or scene structure. It adheres to standard slugline syntax—INT./EXT., location name, and time descriptor—while appending a revision marker to signal change.

Function & Usage

When a location changes from “EXT. PARK – DAY” to “EXT. PARK – DUSK,” the slugline on affected pages is updated. This alerts departments—location, lighting, wardrobe—of the new requirements for dusk shooting. The revision slugline is printed in bold or highlighted to differentiate it from the original, ensuring clarity.

Format & Annotation

A typical revision slugline appears as:

EXT. PARK – DUSK        REVISION 4 – 2025‑07‑24
  • INT./EXT.: Interior or exterior designation.
  • Location: Precise site name.
  • Time: DAY, NIGHT, DAWN, DUSK.
  • Revision Code: Indicates version and date.

This information is also logged in the revision log for continuity tracking.

Best Practices

Sluglines drive departmental preparation—lighting rigs, set dressing, and makeup must align with the new time or locale. Maintaining a master revision log and ensuring digital and paper scripts sync prevents costly oversights and schedule delays.
