Key Film Production Roles: Who Does What On Set

Once preproduction planning is finished, a film moves into production, the actual shooting phase staffed by a distinct set of on-set roles organized into departments: Directing and Continuity, Camera Department, Lighting and Grip, Sound Department, and Art, Wardrobe, and Hair/Makeup. Each department has its own hierarchy and responsibilities, summarized in the table below.
 
If pre-production is where a film is planned, production is where it is actually made. The moment cameras start rolling, a much larger, more specialized crew takes over, organized into departments, each answering to a department head, all coordinating in real time to get the day’s shots in the can. This guide breaks down the key film production roles by department, so it’s clear who does what once a production is actually on set.

What Is the Production Phase?

The production phase is the period of active filming from the first shot of principal photography to the last. Unlike preproduction, which is largely planning and preparation, production runs on a tight daily schedule where every department has to execute in real time, and delays in one department ripple into every other.

Directing and Continuity Roles

This department is responsible for guiding performance and keeping the entire shoot on schedule and logically consistent.

Director

The director guides the creative vision for every shot, working with actors on performance and with department heads to translate the script into filmed scenes.

1st Assistant Director

The 1st assistant director runs the set on a moment-to-moment basis, executing the shooting schedule built in preproduction and keeping the day moving.

2nd Assistant Director

The 2nd assistant director manages cast logistics, distributes call sheets, and coordinates background action, supporting the 1st AD’s schedule from behind the scenes.

Script Supervisor

The script supervisor tracks continuity between takes and scenes, prop placement, costume details, and actor positioning to ensure shots will cut together logically in the edit.

Camera Department Roles

This department is responsible for capturing every image the audience will ultimately see.

Director of Photography (DP)

The director of photography, or cinematographer, is in charge on the film’s cinematography. That means it designs the visual look of each scene and oversees both the camera and lighting teams to execute it during filming.

Camera Operator

The camera operator physically operates the camera during a take, framing and executing the shot under the DP’s direction.

1st Assistant Camera (Focus Puller)

The 1st assistant camera, often called the focus puller, maintains focus throughout a shot and manages the camera’s technical setup and lens changes.

2nd Assistant Camera (Clapper/Loader)

The 2nd assistant camera handles slating each take, maintains camera reports, and manages media cards or film stock.

DIT (Digital Imaging Technician)

The DIT manages color, image quality, and data on set, backing up footage, monitoring exposure and color in real time, and ensuring footage is ready for post-production.

Lighting and Grip Roles

This department is responsible for shaping and supporting the physical light and camera setups on set.

Gaffer

The gaffer leads the lighting team, executing the director of photography’s lighting plan for each setup.

Key Grip

The key grip leads the grip team, handling rigging, camera support equipment, and anything that physically holds or moves lights and cameras.

Best Boy

The best boy is second-in-command to either the gaffer (best boy electric) or the key grip (best boy grip), managing crew scheduling and equipment logistics for their department.

Sound Department Roles

This department is responsible for capturing clean, usable audio directly on set.

Production Sound Mixer

The production sound mixer records and balances all audio captured during filming, operating the sound equipment and monitoring levels in real time.

Boom Operator

The boom operator positions a microphone, usually on a boom pole, to capture clean dialogue while staying out of the camera’s frame.

Art, Wardrobe, and Hair/Makeup Roles

This department is responsible for everything the camera sees on the actors and the physical set itself.

Set Dresser / Props Master

The set dresser or props master manages the physical set and every prop that appears on camera, ensuring items are placed correctly and consistently across takes.

Wardrobe Supervisor

The wardrobe supervisor maintains costume continuity on set, managing fittings, repairs, and changes throughout the shoot.

Hair and Makeup Artist

The hair and makeup artist maintains cast appearance and continuity between takes, adjusting for time jumps, physical wear, or story-driven changes in a character’s look.

Small Indie vs. Studio Production

On a large studio production, every role above is typically staffed by a separate, dedicated person, sometimes with multiple assistants beneath them. On a small independent production, it’s common for these roles to combine: a single camera operator might also pull their own focus, a gaffer might also serve as key grip, or a director might also operate the camera. The department structure still matters at any scale; it just determines which hats one person is wearing at a given moment.
