Who Makes a Play: Roles in Professional Theatre
The Collaborative Art of Theatre
A professional production is never made by one person. It is the result of weeks — sometimes months — of collaboration between dozens of specialists, each accountable for a different layer of the audience’s experience. Understanding who does what is foundational, because when you write about staging choices in the exam you need to name the correct role. A director who wants a cold, isolating atmosphere communicates that intention to a lighting designer, a set designer, a costume designer, and the performers — all of whom then translate it into their own craft. The quality of a production depends on how well those translations align.
The spec lists twelve roles in professional theatre: playwright, performer, understudy, lighting designer, sound designer, set designer, costume designer, puppet designer, director, stage manager, technician, and theatre manager. You need to know what each one does day-to-day and what aspect of the production they are accountable for.
The Playwright and the Director
The playwright provides the raw material: the script, the dialogue, the stage directions, and the characters. Once a playwright hands over a script, they typically have no further creative authority in a professional production — the director interprets the text as they see fit. This is why two productions of the same play can look and feel entirely different.
Day-to-day, a director reads the script repeatedly, researches the historical and social context, meets with designers to agree on a visual world, runs rehearsals, gives notes to performers on character and blocking, and makes final decisions about pacing, focus, and staging. The director’s intention — what they want the audience to think, feel and understand — shapes every choice every other collaborator makes.
Performers and the Understudy
A performer brings a character to life through vocal and physical skills. In rehearsal they work with the director to discover their character’s objectives — what the character wants — and build the physical and vocal pattern of each scene. By opening night, the performer must be able to sustain truthful, technically precise work for every performance, often eight times a week in a professional run. The understudy attends rehearsals and learns the blocking and cues alongside the main cast. If the lead performer is ill or injured, the understudy steps in without a full rehearsal — the production must run seamlessly for the audience.
The set designer creates the physical world of the play: the floors, walls, furniture, and any mechanical elements such as revolves or trucks. They produce scale models and technical drawings so the build team can construct the set precisely.
The lighting designer plans every lighting state — which areas of the stage are lit, with what colour, at what intensity, and through which lanterns — to control focus, mood and the passage of time. The sound designer plans every sound cue: music, diegetic effects (sounds that exist within the world of the play), and underscore. The costume designer creates or sources every item of clothing, hair and make-up that appears on stage, communicating period, social class, character psychology, and ensemble identity through fabric, colour, silhouette and fit.
The puppet designer is a specialist role seen in productions such as War Horse or The Lion King, where large-scale or highly intricate puppets are central to the storytelling. The puppet designer must consider how the object will move, how many operators are needed, and how the performer-audience relationship is maintained when the ‘character’ is not a human body.
The Stage Manager and Technicians
The stage manager is the operational backbone of a production. During rehearsals, the stage manager maintains the prompt copy (the master copy of the script with all blocking, cues, and creative decisions recorded), distributes rehearsal calls, organises the rehearsal room, and communicates between the director and the production departments. During performances, the stage manager calls all technical cues (lighting, sound, flying, automation) into the headsets worn by the operators. Nothing happens on stage without the stage manager’s call.
Technicians operate the equipment during a production: lighting boards, sound desks, flying systems, and stage machinery. They are accountable for technical precision — a cue called one second late, or a lantern focused in the wrong position, changes what the audience sees and experiences.
The stage manager calls all technical cues during a performance. They hold the prompt copy — the single authoritative record of every creative decision — and are the communications hub between all departments. If anything goes wrong on stage, the stage manager co-ordinates the response.
The Theatre Manager
The theatre manager is not directly involved in the creative process but is responsible for the audience’s experience of the building: box office, front-of-house staff, venue licensing, health and safety compliance, and marketing. A successful production that plays to an empty house is a financial failure — the theatre manager ensures the conditions for a full audience are in place.
A common exam error is to credit the director with every staging decision. In professional theatre, the director shapes the overall vision but the specific technical choices belong to the relevant designer. A lighting cue is the lighting designer’s choice (informed by the director’s brief). A costume’s fabric and silhouette are the costume designer’s choice. A sound cue’s reverb and volume are the sound designer’s choice. When you write “as a lighting designer, I would use a gobo to cast shadow patterns across the stage”, you are writing from the correct role. When you write “the director would make the stage darker”, you are blurring two different roles and losing marks.
