What Does a Second AD Do?

A second assistant director produces the call sheet, gets the cast through hair, makeup and wardrobe and delivers them to set on time, runs base camp, handles the daily paperwork, and manages everything happening away from the camera. Where the first AD faces the set, the second AD faces everything behind it.

It is the least visible senior job on a production and one of the most consequential. A shoot where the actors are always ready when the camera is ready feels effortless, and that feeling is manufactured by this person.

The call sheet

The second AD's signature document. Issued every day, usually the evening before, and it is the single source of truth for what happens tomorrow.

It carries the crew call time, individual call times for every cast member and department, the scenes to be shot with their page counts, the location and how to get there, parking, weather, sunrise and sunset, the nearest hospital, and the advance schedule for the day after.

Producing it means gathering information from every department, checking it, and getting it approved by the first AD and the production office before it goes out. It is done at the end of a long shooting day, which is why the second AD is often the last person working.

The dedicated chapter on call sheets covers the document itself in detail. What matters here is that a wrong call sheet costs the production real money the following morning, so accuracy is the whole job.

Cast management

The core operational responsibility, and it is a scheduling problem in miniature.

An actor's morning has a sequence: arrive, sign in, breakfast, hair, makeup, wardrobe, and then to set. Each stage has a duration, and the second AD works backward from when the actor is needed on camera to determine their call time. Get it wrong in one direction and the actor sits in a trailer for two hours. Get it wrong in the other and ninety people wait.

Through the day the second AD tracks where every actor is, keeps them informed, delivers them to the floor when the first AD calls for them, and releases them when they are done. On a day with twelve cast members and three overlapping makeup requirements, this is genuinely difficult.

They also handle the cast paperwork: sign-in sheets, out times, and the timesheets that determine what people get paid.

Base camp

The trucks, trailers, catering, holding areas and everything that constitutes the production's temporary village.

The second AD runs it: making sure it is set up correctly, that cast have what they need, that background artists are held somewhere sensible, that catering happens at the right time, and that the whole thing gets packed up at wrap.

On a large production this is a substantial logistics operation, sometimes with a dedicated base camp AD.

The paperwork

A steady flow of daily documents, most of which have contractual or legal weight.

Movement orders. Instructions telling everyone how to get to a location, where to park, and any access restrictions. Issued in advance for anything unfamiliar.

Sign-in sheets and timesheets. Who arrived, when, and when they left. This feeds payroll and, where working time rules apply, compliance.

Production report contributions. The daily record of what was shot, how many pages, how many setups, what time the first and last shot happened, and any incidents. Combined with the script supervisor's and the production office's records.

Background vouchers. Extras' paperwork and payment records.

Cast deal information, working with the production office on who is on which contract and what their working conditions are.

None of this is glamorous, and all of it is the evidence trail that proves a production was run properly.

Background artists

Depending on the size of the production, background may sit with the second AD or with a third AD. Either way it belongs to the AD department: booking numbers, holding them, costuming them through the wardrobe pipeline, briefing them, and moving them to set.

Large crowd days are effectively a second production running in parallel, and they are usually where the AD department is most stretched.

The department structure

First AD on the floor. Second AD at base camp and on paperwork. On bigger shows, a key second AD stays with the first AD on set while a second second AD runs base camp, because one person cannot be in both places on a large unit.

Below them, third ADs and set PAs handle background, lock-ups and the endless small errands that keep a set moving.

The career path

The AD department has the clearest progression of any on a film: runner, then set PA, then third, then second, then first. Each step takes years and each has a genuinely different skill set.

Second AD is where the paperwork discipline is learned, and it is the step that teaches you the production as a whole system rather than as a shooting floor. A lot of very good first ADs, production managers and line producers came up through it.

It is worth saying plainly that this is a career, not a waiting room. The people doing it are specialists, and treating the AD department as aspiring directors is both wrong and slightly rude.

On a small film

On a short, the second AD's functions are the ones most likely to be dropped entirely, and the symptoms are recognizable: nobody knows what time to arrive, actors turn up in the wrong order, and there is no coherent record of what happened.

The minimum viable version, even on a three-day shoot:

• Issue a call sheet the night before. Even a single page. Time, place, scenes, who is needed when.
• Give each actor an individual call time, worked back from when they are needed and how long they take to prepare.
• Have one person responsible for knowing where the cast are.
• Record actual arrival and wrap times. You will need them if anything goes wrong, and you will want them for scheduling the next film.

Next

Out of the AD department and into camera. Next: the director of photography, and what they actually control.
