Assistant Director Role: What It Involves in Theatre and Film
The assistant director role means two quite different jobs, depending on whether you are in a rehearsal room or on a film set. In theatre, an assistant director (AD) is a creative partner who supports the director’s vision, researches the play, watches rehearsals with fresh eyes and acts as a bridge to the cast. In film and television, the AD is a logistical manager who runs the schedule, the call sheets and the safety of the set.
This guide explains both, shows how the theatre role differs from a stage manager’s, and sets out realistic ways for a teenager to begin. We are a youth theatre in Berkshire, so we write from the rehearsal room first.
TL;DR
Theatre AD: a creative-support role. You research, observe, run warm-ups and parallel rehearsals, and connect the director with the company.
Film and TV AD: a logistical and managerial role. The 1st AD runs the set and the schedule, the 2nd AD handles call sheets and cast movements.
Not a stage manager: the AD serves the director’s creative vision, while the stage manager keeps the production running safely and on time.
Starting young: watch rehearsals closely, take on ensemble responsibility, learn the backstage side, and look at schemes such as the National Youth Theatre REP Company.

Two jobs with one name
People searching for this role often land on film pages, and that is understandable. The film version of the job is the better known one. But the two roles share only a title and a love of organisation.
On a film set the AD is not there to make creative decisions. According to Wikipedia’s overview of the role, the film AD tracks daily progress against the shooting schedule, arranges logistics, prepares daily call sheets, checks cast and crew, and keeps order on set. The director concentrates on performance while the AD makes sure the day actually happens.
In UK theatre, the job leans the other way. Get into Theatre describes it as a creative-support role: researching the context of the script, helping with script development, supporting the director in rehearsal and acting as a link between the director and the wider company. The Royal Shakespeare Company frames it simply: the assistant director is there to help deliver the director’s creative vision.
If you are a teenager who loves stories, working with people and thinking about why a scene works, the theatre version is probably the one you are looking for. The rest of this guide focuses on it, then returns to film so you can compare.
What a theatre director does, and why they need an assistant
To understand the assistant, start with the person they assist. The director is the central visionary of a production. They interpret the script, cast the show, plan the rehearsal process and work with designers of set, costume, lighting and sound so that every element feels like part of one performance. The American Association of Community Theatre puts it plainly: the director sets the vision for the production for everyone involved, and has the challenging task of bringing many complex pieces together.
That is a lot for one person to hold. Director Katie Mitchell has described directing as collaborative, relying on a team that spans performers, text, design, movement, lighting, sound, music and video, as summarised in this study of her practice. Someone has to help those specialist areas talk to each other. Often, that someone is the assistant director.
In a rehearsal room the director is usually looking at the whole picture: the shape of the act, the pace, the staging. A second pair of eyes catches the small things. The RSC describes the assistant as an extra set of eyes and ears who can spot details or issues the director might miss.
Assistant director responsibilities in the rehearsal room
No two productions divide the work in exactly the same way, and a good AD agrees the split with the director early. Still, the same themes come up again and again.
Before rehearsals begin
The work starts before anyone walks in. The RSC notes that an AD may do pre-rehearsal research on the context of the play, the playwright or a concept the director wants to explore. For a musical, that might mean the period the show is set in, how the original production was staged, or the social background of the characters.
Get into Theatre adds that ADs may help with script development, which in a youth setting often means cutting, reordering or checking the text for length and clarity.
During rehearsals
This is where most of the job lives. Typical tasks include:
Observing and noting. Watching a run with fresh eyes and reporting what you saw, not what you hoped to see.
Leading warm-ups. Getting the company physically and vocally ready, and setting the energy for the day.
Running parallel rehearsals. Taking a smaller group into a second room while the director works with others.
Supporting the director. Keeping track of decisions, so a moment agreed on Tuesday is still there on Friday.
Being the bridge. Get into Theatre lists this as a core duty, and the RSC adds that performers often bring the AD concerns they feel uncomfortable raising with the director directly.
That last point deserves a moment. It means an AD needs tact and discretion as much as theatrical knowledge. You are not the director’s spy or the cast’s lawyer. You are the person who helps small problems get solved before they become big ones.
After the show opens
The job does not end on press night. According to the RSC, ADs often manage understudy rehearsals and make sure that if an actor is unavailable, the understudy is ready to step in. That requires keeping a close watch on the production well after it has opened.
In youth theatre the equivalent is often cover and double casting, which is a good reason to read our guide to protecting young voices with double casting.
Assistant director vs stage manager
This is the question beginners ask most, because both people sit near the director and both seem to be everywhere. The difference is who each one serves and what each one owns.
Assistant director | Stage manager | |
Main purpose | Supports the director’s creative vision | Keeps the production organised, safe and on time |
In rehearsal | Observes, researches, leads warm-ups, runs parallel rehearsals | Records blocking, runs the room, tracks props and cues, communicates with other departments |
Relationship to the cast | Bridge between actors and director | Point of contact for practical and safety matters |
During performances | Often finished once the show opens, apart from understudies | Calls or runs the show every night |
The table is a simplification, since small companies often blend the jobs. But the principle holds. Ask yourself whether you are more excited by the question “what is this scene about?” or “is everything ready, safe and in the right place?” The first points to directing, the second to stage management. Both are respected careers, and both need real skill.

The film and TV assistant director
Since many readers arrive looking for the screen job, here is how it works. Film and TV have a ladder of AD roles.
The ScreenSkills job profile calls the first AD the director’s right hand. The 1st AD plans the filming schedule with the director, the director of photography and other heads of department, and then keeps the set moving to that plan. They also maintain set safety.
The 2nd AD is the main off-set contact. ScreenSkills’ role description for second ADs says they are the main contact for departments such as production, locations and facilities. They break down the script, organise fittings and rehearsals and prepare call sheets. Wikipedia adds that 3rd ADs typically look after background actors and crowd control.
There is also a frequent mix-up between the film AD and an “assistant to the director”. Wikipedia points out that the film AD role is logistical and managerial, while an assistant to the director tends to be more involved in creative work and personnel across the project. If you read a job advert, check which one it really is.
The National Careers Service profile says people can start as a runner or production assistant. That route is a long way from a youth theatre rehearsal room, but the shared ground is real: calm under pressure, clear communication and respect for the whole team.
Skills that make a good assistant director
Whatever the setting, the same qualities keep appearing.
Observation. You need to see what is actually happening on stage, not what you expect.
Discretion. People will tell you things. You protect confidences and know when something needs to go to a safeguarding lead or the director.
Preparation. Research, notes and a ready answer to “what happened in this scene last week?” make you valuable.
Steadiness. Director Marianne Elliott, in a Q&A with WhatsOnStage, speaks about leadership as being part of the high-level planning of a theatre, not just one show’s rehearsals. That calls for multitasking and a level head.
Humility. The job is to serve someone else’s vision. Your ideas matter, but you offer them at the right moment and in the right way.
Knowing the room. You understand what a rehearsal needs. Our post on which rehearsal happens when breaks down the types.
And you still need to know how it feels to be an actor. Understanding stage directions and hitting your marks or how to rescue a flat scene with blocking templates gives you a vocabulary the cast will trust.
What does a student assistant director do?
Young people rarely get a paid AD post, but the practical training is real. The National Youth Theatre’s Bryan Forbes REP Assistant Director opportunity is a useful model. Its role description says the purpose is to learn the skills of a director through practical experience, supporting the work of the NYT REP Company.
Training of this kind is hands-on. It can include attending production and design meetings, providing research materials, supervising second rehearsals such as music or dance calls, and standing in for actors during technical rehearsals so the technical team can check sightlines and lighting. The same document records a bursary of £14,000 for the 2025/26 assistant director trainee.
A student at school, college or a youth company can copy the spirit of this at a smaller scale:
Ask whether you can sit in on a rehearsal and take notes.
Offer to run a warm-up for the company.
Volunteer to lead a small group on a song or a dance call.
Read the play and prepare a one-page note on its context for the director.
Learn how a first rehearsal is set up, so you understand the beginning of the process.
Each of these is a small step, but together they build a portfolio of real experience that you can talk about in an application.
Routes in for young people in the UK
There is no single qualification. Get into Theatre notes that you do not need a degree for the assistant director role, and many directors began as actors, stage managers, writers or musicians.
Some practical routes:
Youth theatre. Regular rehearsals and a staged show teach you how a production grows. Our guide to what youth theatre really is explains why a public performance matters.
National youth schemes. The NYT REP Company, mentioned above, is aimed at people at the start of a career, with intensive and practical training.
Film and TV entry schemes. ScreenSkills Trainee Finder lists assistant director and floor runner among its departments. Check the current eligibility rules on the page, as they can change from year to year.
Drama school and university. Applications often ask for a recent photo alongside your CV, and a good set of actor headshot photographers in London can help you present yourself well if you also audition.
Whichever route you take, keep a record of what you have done: shows you observed, warm-ups you led, notes you gave. Specific evidence beats general enthusiasm every time.
Our perspective: what we think young assistant directors need
At Ocean we work with 14 to 19 year olds, and we see something every term: the young people who grow most are rarely the ones who start with the most confidence. They are the ones who are curious about how the whole show fits together.
We would encourage any teenager interested in directing to start by being a very good company member. Learn the music, be early, listen to notes and notice how a rehearsal is run. Watch how a director adjusts a scene when it is not working. Ask questions at the right moment. That attention is the real beginning of an assistant director’s craft.
Our company is built on weekly rehearsals, professional direction and two large-scale musical theatre productions each year, with extra opportunities in singing, acting, dancing and leadership roles in ensemble performances. We do not hold entry auditions, because we believe the benefits of theatre belong to everyone who wants to join in. A supportive, friendly group is where people feel brave enough to try leading a warm-up or helping a friend with a scene.
If directing is your dream, be patient and generous. The role asks you to make someone else’s vision stronger, and that is a lesson in teamwork that you will carry into any job.

Learn how a production works with Ocean Theatre
You cannot understand directing from a page. You learn it by being in the room, watching a show grow from the first read-through to opening night. The Company (14-19) is our Berkshire youth theatre programme, with professional-led training and fully staged musicals. Our current production, CRAZY FOR YOU, is a chance to see what that process produces. If you or your teenager would like to join us, the Company page is the place to begin.
Common mistakes when starting out
Mistaking the AD for a mini-director. You are there to support the director’s vision, not to replace it.
Ignoring the backstage team. Understand how stage management and crew work. Our checklist of backstage etiquette rules is a good start.
Overlooking the music and dance calls. These are where ADs often get their first real chance to lead. Our piece on dancing for actors shows how varied these sessions can be.
Giving notes in public. Save feedback for the director, and for private moments unless asked.
Waiting for permission to learn. Observe, read, ask and volunteer.
FAQ
What is the role of an assistant director in theatre?
An assistant director supports the director’s creative vision. That means researching the play, observing rehearsals, leading warm-ups, running parallel rehearsals and acting as a link between the director and the cast. They may also oversee understudy rehearsals once the show is running.
Is assistant director the same as stage manager?
No. The assistant director serves the creative vision, while the stage manager keeps the production organised, safe and on schedule. In small or amateur companies one person may do a bit of both, but the responsibilities are different.
What does an assistant director do on a film set?
It is a logistical job. The 1st AD plans and runs the shooting schedule and keeps the set safe. The 2nd AD prepares call sheets and manages cast movements and contact with other departments. The 3rd AD often looks after background actors.
Can a teenager be an assistant director?
Yes, in a youth or school production, where the opportunity is often informal. Start by observing, taking notes, leading warm-ups and helping with small rehearsals. National schemes such as the NYT REP Company offer more structured training for people starting their career.
