What Does a 1st AD Actually Do? The Job Nobody Explains

The one-line version

The 1st AD runs the set so the director can direct.

That sounds like a support role. It isn't. The 1st AD owns the schedule, controls the floor, and carries formal responsibility for safety. On most productions they're the single largest determinant of whether days finish on time.

What they actually do

In prep

The 1st AD does the script breakdown — reading the script scene by scene and tagging every element the production needs. Cast, props, wardrobe, vehicles, stunts, effects, locations.

From that breakdown they build the shooting schedule: strips ordered into shoot days, grouped to cut company moves, minimise cast hold days and protect turnaround.

This is where a production is won or lost. A well-built schedule saves more money than any decision made on set.

On the day

• Calls the shots — literally. "Rolling," "background action," "cut."
• Runs the floor. Keeps the set quiet, keeps departments moving, keeps the next setup being prepped while the current one shoots.
• Manages the clock. Knows how many setups remain, how much time is left, and whether the day is achievable.
• Protects the director's attention. Everything that doesn't require the director gets absorbed by the AD department.
• Owns safety. Runs safety briefings, enforces protocols, has the authority to stop work. This is a formal responsibility, not a courtesy.

Between days

Reviews the next day's call sheet, confirms turnaround is legal, adjusts the schedule when the day didn't go to plan, and signs off the daily production report.

The AD department

1st AD — runs the set and owns the schedule.

2nd AD — prepares call sheets and the daily production report, manages cast through makeup and wardrobe, handles background. Usually based at unit base rather than on the floor.

3rd AD / 2nd 2nd — on the floor, cueing background, managing crowd, running the practical side of what the 1st calls for.

Set PA / Runner — entry point to the department. Where most ADs start.

Titles and exact splits vary by region — UK, US and Indian productions divide these differently — but the shape is consistent.

What makes a good one

They can say no. A 1st AD who agrees to everything produces a schedule that fails in week two. The job requires telling a director that six setups before lunch isn't happening.

They're calm when it goes wrong. It always goes wrong. The 1st AD's mood propagates across sixty people faster than any instruction.

They think two setups ahead. By the time the current shot is finishing, the next one should already be lit and rigged.

They protect the crew. Turnaround, meal breaks, safety. A crew that trusts the 1st to enforce these works harder for them.

They're honest about time. A 1st who claims a day is achievable when it isn't loses the room permanently.

How you become one

There's no qualification. The path is almost always:

Runner → 3rd AD → 2nd AD → 1st AD

Expect several years. The step from 2nd to 1st is the hard one, because it's the point where you become responsible for the schedule and the floor rather than executing someone else's plan.

What accelerates it: learning to break down a script properly, understanding scheduling logic deeply, and being the person on set who's already thought about the problem everyone else is about to notice.

Safety training is increasingly expected and in many regions effectively required.

What it pays

Rates vary enormously by region, budget tier and whether the production is union. A 1st AD on a studio feature and a 1st AD on an indie short are doing the same job for very different money.

We publish a role-by-role day rate guide with current figures for the Indian market. For other regions, check local guild or union rate cards, which are usually published.

The misconception

The most common misunderstanding is that the AD is the director's assistant. The name causes this and it's wrong.

The director is responsible for what the film is. The 1st AD is responsible for whether it gets made in the time and conditions available. Those are different jobs, and on a functioning set they're held by people who trust each other completely.

If you're hiring, find an AD here. If you're becoming one, start by learning to break down a script — everything else in the job builds on that.
