Film Production Careers & On-Set Leadership
The Role of the Assistant Director: What Does an AD Do on a Film Set?
From the first pre-production meeting to the final company wrap, assistant directors help turn a screenplay into a shootable plan. Here is what the job really involves, who does what on the AD team, and why great filmmaking depends on great coordination.
On a film set, the director is responsible for the creative vision. The cinematographer helps shape how that vision is photographed. But who makes sure the cast arrives, departments are ready, the day stays on schedule, and everyone knows what happens next? Much of that responsibility belongs to the assistant director (AD) team.
Despite the title, an assistant director is not simply the director’s personal assistant. ADs are production leaders who coordinate people, time, locations, and logistics so that the director and crew can concentrate on making the film. Their work begins long before anyone calls “Action!”
1. What Does an Assistant Director Do?
The assistant director helps bridge creative ambition and production reality. The AD department translates the shooting plan into coordinated action, working closely with the director, unit production manager (UPM), production office, department heads, cast, and crew.
A strong AD knows both what the director wants to accomplish and what the production can realistically accomplish today. Those are not always the same thing. If a five-page dialogue scene calls for eight elaborate camera setups, the AD needs to understand how the coverage affects time, equipment, personnel, and the scenes still waiting to be filmed.
Important distinction: The AD department helps plan and coordinate a safe, orderly shoot, but safety is a shared responsibility. Stunts, weapons, special effects, rigging, and other specialist activities require appropriately qualified personnel and procedures. An AD does not replace those specialists.
Across productions, the central responsibilities typically include preparing and updating schedules, coordinating the day’s work, communicating changes, tracking progress, facilitating cast movement, supporting compliance with applicable work rules, and responding when conditions change.
2. The Assistant Director’s Work Begins in Pre-Production
An efficient shoot is built before the first day of principal photography. In preparation, the AD team works through the screenplay scene by scene to identify what the production will need and when those needs must come together.
Identify cast, background performers, locations, props, vehicles, wardrobe, effects, stunts, animals, and special requirements. The breakdown gives the team a foundation for planning. Read more in our screenplay breakdown guide.
Group scenes by real filming location, cast availability, day or night requirements, scene complexity, travel, company moves, and other constraints. The step-by-step film scheduling workflow explores this process in depth.
Two script pages can take very different amounts of time depending on coverage, blocking, lighting, action, weather, or company moves. The AD consults with the director, cinematographer, UPM, and departments when estimating the day.
Make sure scheduled elements can actually be provided on the required dates. An available location does not help if an essential actor, specialty prop, or effects team cannot be there.
During prep, the schedule may be revised repeatedly. That is normal. The objective is not to create a perfect calendar that never changes; it is to create a plan that exposes trade-offs early enough to make informed decisions.
3. What Does the Assistant Director Do on Set?
During production, the AD team becomes the operational hub of the shooting day. They do not make every decision, and they cannot solve every issue personally, but they keep information and people moving in the right direction.
Run the day’s schedule
Track completed work, anticipate delays, coordinate the next setup, and communicate revisions to the production team.
Coordinate cast and background
Work with the appropriate departments so performers are notified, prepared, and ready when required.
Manage set communication
Call for quiet and lockups as appropriate, relay instructions, and keep departments aware of the next scene or move.
Support safe working practices
Coordinate safety briefings and specialist preparations while following the production’s established procedures and reporting channels.
One of the most useful things an experienced AD can do is recognize trouble before it arrives. If a storm is approaching, a child performer has limited availability, or a practical effect needs substantial reset time, the AD should bring the problem into the conversation early.
Keeping a set moving does not mean rushing unsafe work or ignoring required meal, rest, and turnaround periods. It means developing a realistic plan and revising it responsibly when circumstances change.
4. Understanding the Assistant Director Team
The number of assistant directors and their precise duties vary by country, production size, budget, collective bargaining agreement, and local custom. A US feature may use a different staffing structure from a UK television production. These descriptions are a practical guide, not a universal job specification.
First Assistant Director (1st AD)
The 1st AD leads the AD department and is primarily responsible for organizing the shooting schedule and overseeing the day-to-day execution of the plan. They work closely with the director, UPM, production team, and department heads. The 1st AD typically directs set operations, tracks progress, and adjusts priorities as the day unfolds.
Second Assistant Director (2nd AD)
The 2nd AD often manages important off-set coordination: preparing and distributing call sheets, tracking cast logistics and paperwork, communicating with production, and coordinating with departments about upcoming needs. On a busy show, the 2nd AD is essential to ensuring tomorrow’s shoot is being prepared while today’s shoot is underway.
Second Second Assistant Director (2nd 2nd AD)
Some US productions employ a 2nd 2nd AD to assist the 2nd AD and manage areas such as background performers, base camp, cast movement, or complex logistics. Responsibilities depend on the production’s staffing arrangement.
Third Assistant Director (3rd AD) and Additional ADs
The 3rd AD title is more common in some international production systems, where the role may include coordinating background performers and moving cast through the production process. Additional ADs may support crowd-heavy or multi-unit productions. Titles such as “4th AD” are not used consistently everywhere and should not automatically be equated with a Key Production Assistant.
Production Assistants (PAs)
Set PAs provide vital practical support: relaying messages, assisting with set lockups, helping coordinate movement, and performing assigned production tasks. Some PAs pursue careers in the AD department, but the pathway and eligibility rules depend on the production market.
Guilds and agreements: For union productions, consult the applicable agreements and requirements, including those of the Directors Guild of America in the United States. Crew size, responsibility, working conditions, and hiring qualifications are not identical across productions.
5. The Production Documents Every AD Should Understand
The AD’s work is supported by documents that answer different questions. They should reflect the same current production plan, but each serves a distinct purpose.
Shooting schedule & stripboard
Which scenes shoot on which dates, and how are cast, locations, and production elements grouped? See Film Scheduling Workflow.
Call sheet
What happens tomorrow, where, and at what time? It communicates cast and crew calls, scenes, locations, contacts, and special instructions. See the call sheet guide and free template.
Day Out of Days (DOOD)
When does each actor or important element start, work, hold, and finish across the schedule? See What Is a Day Out of Days Report?
Daily production report (DPR)
What did the production actually accomplish, and what changed? The appropriate production personnel complete and review the report. See What Is a Daily Production Report?
Also useful are the one-liner, cast lists, location lists, production calendars, safety communications, and department-specific reports. Our Film Scheduling Reports Explained article shows how these documents work together.
The AD team works with other departments to verify accurate information. For example, cast work records and performer-related union documentation are subject to a production’s payroll, union, and production-office procedures; they should not be assumed to fall entirely on one assistant director.
6. A Day in the Life of a First Assistant Director
Imagine an independent feature shooting a restaurant scene, two exteriors, and an evening car scene. The following is an illustrative schedule, not a prescribed call-time template.
Before call Review the day with production and departments; confirm any weather, location, or safety issues.
Morning Coordinate the first rehearsal and camera setup, then confirm that the crew is ready before rolling.
Midday Track the scenes completed, evaluate remaining work, and coordinate the planned meal period.
Afternoon A location becomes unavailable earlier than expected. Discuss options with the director and UPM, then update affected departments.
Late day Finish achievable work safely, identify anything that must be carried over, and communicate changes for the next call sheet.
After wrap Review the day’s progress and help prepare for tomorrow; the 2nd AD and production office coordinate the next day’s call sheet and distribution.
What makes this role challenging is not simply the number of tasks. It is that every decision affects other people. Moving one scene may change an actor’s availability, a location booking, an equipment rental, or even the next day’s budget.
7. What Skills Make a Good Assistant Director?
Assistant directing is a leadership role, but strong leadership on a film set is not the same as being the loudest person with a headset.
- Communication: Give clear, specific directions and confirm that information reaches the right departments.
- Prioritization: Know which problems require immediate action and which can be resolved after the setup.
- Scheduling judgment: Understand how scene complexity, company moves, availability, and coverage affect time.
- Diplomacy: Negotiate competing needs without turning every disagreement into a crisis.
- Calm under pressure: Recognize when the plan must change and communicate the new plan quickly.
- Safety awareness: Identify concerns, raise them promptly, and involve the qualified people responsible for specialized work.
- Respect for the crew: Protect reasonable planning, clear calls, breaks, and professional working relationships.
How do you become an Assistant Director?
Many people gain experience through set production assistant work, production office roles, or lower-level AD positions. Film schools and independent productions can help build familiarity with call sheets, schedules, set etiquette, and department coordination. Larger union productions may have specific qualifications and entry routes.
It is possible to move between directing and assistant directing, but they are different professions with different everyday responsibilities. The AD career path is often attractive to people who enjoy production management, logistics, and the challenge of helping a team complete its creative work.
8. Tools That Help Assistant Directors Prepare and Run a Shoot
The most valuable scheduling tool is not the one with the flashiest dashboard. It is the one that helps the AD understand the plan, spot conflicts, revise scenes, and communicate reliable information to the rest of the production.
Gorilla Scheduling Online: From Breakdown to Shooting Schedule
Gorilla Scheduling Online helps filmmakers import screenplays, break down scenes, organize production elements, build stripboards, manage shoot days and create scheduling reports in a browser-based workflow. This makes it relevant to the work assistant directors and production managers perform during preparation.

Shot Monkey: Storyboards, Setups, and Shot Lists
The director and cinematographer generally lead creative shot design, while the AD evaluates how the planned coverage fits the schedule. Shot Monkey is Jungle Software’s dedicated online storyboard and shot-list application. It organizes shot groups, camera setups, and individual shots, including timing and production details. That information can help the AD discuss realistic setup time and coverage with the creative team.
For more on this distinction, see Storyboard and Shot List Software: Plan Every Shot Before You Shoot.
Scheduling and Budgeting Are Connected
Every additional location, shoot day, and complicated setup can affect a production budget. The AD and UPM make scheduling decisions with those consequences in mind. Gorilla Budgeting Online supports the budgeting side of pre-production, while the scheduling team focuses on an achievable plan.
9. Practical Assistant Director Checklist
Before approving a shooting-day plan, an AD should be able to answer questions like these:
- Are the scenes, locations, and planned cast accurate?
- Have major stunt, effects, vehicle, child-performer, animal, or location restrictions been identified?
- Do the director and cinematographer understand the expected coverage and setup requirements?
- Are company moves, weather, daylight, and time constraints accounted for?
- Have department heads been consulted about special equipment, props, costumes, and preparation?
- Have applicable meal, rest, turnaround, and working-time requirements been reviewed?
- Are the latest schedule and call sheet details being communicated consistently?
- Is there a workable alternative if weather, availability, or technical problems disrupt the plan?
No checklist eliminates every surprise. It does, however, reveal preventable problems before those problems become tomorrow’s production report.
