Script Supervisors / Continuity & Allied Production Specialists Guild (IATSE Local 871)

Overview

The Script Supervisors / Continuity & Allied Production Specialists Guild, operating as IATSE Local 871, is the union representing script supervisors, production office coordinators, production supervisors, and other production specialists working in motion pictures and television in the United States. Founded in 1953, Local 871 covers some of the most detail-oriented and organizationally demanding roles in the below-the-line production hierarchy.

The script supervisor -- sometimes called the continuity supervisor in international production contexts -- is responsible for tracking every detail of how a scene has been shot across all takes and setups: actor positions, costumes, props, hair, makeup, camera coverage, dialogue as scripted versus as performed, and the timing of all action. This meticulous tracking ensures that the editor has complete information about what was shot and that visual continuity is maintained when shots from different setups and shooting days are cut together. A missed continuity detail that goes untracked by the script supervisor can create uncorrectable visual inconsistencies in the finished film.

The Script Supervisor's Role

The script supervisor works directly with the director and the editor throughout principal photography. Before shooting each scene, the script supervisor reviews the script, previous shots, and continuity records to flag any potential continuity issues. During each take, they track every observable detail -- making detailed notes and often photographs -- that the editor will need to cut the scene correctly. At the end of each shooting day, the script supervisor prepares detailed facing pages (also called editor's notes or continuity reports) that accompany the day's footage to the editing room, giving the editor a complete record of what was shot and how.

The script supervisor also maintains the lined script -- a marked-up copy of the script showing which takes cover which lines -- and tracks actual screen time versus scripted time, which is critical information for the director and producer managing the schedule.

Production Office Coverage

Local 871's jurisdiction extends beyond script supervisors to production office coordinators (POCs) and production supervisors -- roles that manage the production office's administrative operations during principal photography. POCs coordinate travel, logistics, communications, and the flow of production paperwork that keeps a complex shoot organized. Their work is essential but largely invisible to people outside the production office.

What Filmmakers Should Know

For directors, the script supervisor is one of the most important set relationships after the DP and first AD. An experienced script supervisor who anticipates editorial problems before they occur -- flagging potential continuity issues before a scene wraps rather than after -- saves significant post-production time and can prevent editorial problems that would otherwise require expensive reshoots.

For producers, Local 871 rates for script supervisors and production coordinators are both meaningful below-the-line budget items. The script supervisor's notes and the production coordinator's organizational infrastructure are not optional overhead -- they are essential to the smooth functioning of any professional production.
