Filmmaking Dictionary: Number 2 / Second Assistant Director (2nd AD)
Definition
The Second Assistant Director, or 2nd AD, helps turn the shooting plan into workable arrangements for cast and departments. Working closely with the 1st AD, the 2nd AD commonly coordinates cast readiness, prepares call sheets and maintains communication between the set, unit base and production office.
The exact division of work depends on the production’s size, region and AD team. A larger show may have a key 2nd AD, additional seconds and separate staff handling background performers or base operations.
What the 2nd AD Handles
- Call-sheet preparation: Gather and reconcile the information needed for the following shooting day.
- Cast coordination: Track calls, transport, fittings, rehearsals and readiness.
- Department communication: Pass confirmed timing and requirement changes to the people affected.
- Preparation: Help identify upcoming cast, background and logistical requirements.
- Team coordination: Work with the rest of the AD department so people arrive where they are needed.

Why Readiness Takes Planning
An actor’s call time is not necessarily the time they step onto set. Travel, paperwork, costume, hair and makeup may all need to happen first. If one stage takes longer than expected, the 2nd AD needs reliable information before telling the 1st AD when the performer will be ready.
For example, a scene moves earlier in the day. Bringing the actor to set immediately may achieve nothing if their costume change and makeup work are unfinished. The useful response is to confirm the new requirement, coordinate the departments involved and communicate a realistic readiness time.
The 1st AD and 2nd AD Relationship
The 1st AD typically leads the immediate running of the shooting floor and the day’s schedule. The 2nd AD supports that work through preparation and coordination beyond the camera’s immediate area. Clear updates let the 1st AD make decisions using the actual state of the production.
Good call sheets also depend on accuracy rather than speed alone. Names, locations, reporting times and special requirements must agree with the approved plan. An unconfirmed change copied into several messages can create more confusion than a single delayed update.
Common Mistakes
- Confusing the 2nd AD with a second unit director.
- Treating an estimated readiness time as a confirmed one.
- Assuming the same AD structure and responsibilities apply on every production.
