Working with actors II: rehearsal and performance

Lesson 5 gave you the language of direction. This lesson is about using it over time: in rehearsal before the shoot, in the short rehearsals on set before each scene, and across the many takes and days of a production. Film performance is unusual because it is built in pieces. An actor may play the end of a relationship on Monday and its first meeting on Thursday, repeat a single moment fifteen times from four angles, and then wait three hours before the next scene. The director's job is to help each actor build a coherent, living performance out of those fragments.

The lesson covers why and how to rehearse for film, how to use improvisation, how to protect freshness, how to manage emotional continuity across an out-of-order schedule, how to shape performance across takes and set-ups, and how to handle common difficulties with actors.

Why rehearse for film?

Film directors disagree about rehearsal. Some rehearse extensively, treating it as the place where the film is discovered. Others rehearse very little, fearing that repetition will drain spontaneity before the camera rolls. Most take a middle path: they rehearse to build relationships, clarify the story and solve problems, but stop short of fixing performances in detail.

Rehearsal is especially valuable for relationships. Two actors playing sisters who have known each other for forty years meet as strangers. Time spent together, talking about the characters' shared history, improvising scenes that are not in the script and simply getting comfortable, helps them arrive on set with a relationship rather than having to invent one between takes. Rehearsal is also where actors raise questions about the script, and where the director can test whether scenes work before expensive shooting days.

The table read

A table read gathers the cast, director, writer and often producers and heads of department to read the whole script aloud. It is frequently the first time the director hears the story with the actors' voices. Its value is mostly diagnostic: you hear which scenes drag, which jokes land, which lines are hard to say and how the actors sound together. Writers often revise after a table read.

A table read is not the place for detailed direction. Actors are usually asked to read without performing fully. The director's main job is to listen, make notes and set a warm, collaborative tone. Afterward, the director and writer can discuss changes, and the director can speak individually with actors about their characters.

Running prep rehearsals

A typical prep rehearsal of a scene might follow a sequence like this. Begin by reading the scene at the table and talking about what happens: the circumstances, what each character wants and what is at stake. Answer questions. Then put the scene on its feet in a rough space, letting the actors move as they feel the scene, without fixing blocking. Watch for discoveries. Give a few playable notes and run it again. Stop before it becomes rehearsed; the goal is understanding, not a finished performance.

Directors should be careful about the most emotional scenes. Running the climactic scene of a film at full intensity ten times in rehearsal can exhaust an actor and drain the moment of its first-time quality. A common practice is to explore such scenes at lower intensity in rehearsal, marking the emotional peaks, and to save full intensity for the camera.

# scenes: (name, pages, emotional weight 1-3, cast count)
scenes = [("Kitchen", 1.6, 3, 2), ("Funeral home", 1.3, 2, 5), ("Car", 0.8, 1, 2),
          ("Garden", 1.1, 3, 2), ("Bus station", 1.5, 2, 3)]
base_minutes_per_page = 30
available_hours = 12
raw = {}
for name, pages, weight, cast in scenes:
    # heavier and larger scenes get more time, but with diminishing returns
    raw[name] = pages * base_minutes_per_page * (1 + 0.4 * (weight - 1)) * (1 + 0.1 * (cast - 2))
scale = available_hours * 60 / sum(raw.values())
for name, minutes in raw.items():
    print(f"{name:13s} {minutes * scale:5.0f} min")
print(f"Total: {sum(raw.values()) * scale / 60:.1f} h of {available_hours} h available")

Kitchen         201 min
Funeral home    165 min
Car              56 min
Garden          138 min
Bus station     161 min
Total: 12.0 h of 12 h available

The formula is arbitrary, but the principle is sound: weight rehearsal toward scenes that are emotionally demanding, involve several actors or carry the film's turning points, and spend less on simple transitional scenes. Always keep some time unallocated for problems that emerge.

Improvisation

Improvisation can be one of the most powerful rehearsal tools. Directors use it to build backstory, to explore relationships and to find behaviour that feels lived-in. For the sisters in the kitchen scene, a director might ask the actors to improvise the last Christmas Maya came home, or a phone call between them the night their mother was diagnosed. These scenes will never be filmed, but they give the actors shared memories that inform every look in the kitchen.

Improvisation can also be used on scripted scenes: the actors play the scene in their own words, which often reveals what the characters really want and where the scene's energy lies. Some directors then return to the script; others incorporate discoveries into revised dialogue, with the writer's involvement. A few directors shoot largely improvised films, which requires a very different production approach and careful agreements with actors about authorship and credits.

Good improvisation needs structure. Give the actors circumstances, a relationship and objectives, set a time limit and stay out of the way. Afterward, discuss what was discovered. Avoid improvisations that pressure actors into personal disclosures or uncomfortable physical situations.

Protecting freshness

The central paradox of film acting is that the actor must know the scene thoroughly yet play it as if for the first time. Over-rehearsal and over-direction are the usual enemies of freshness. Signs that a scene has gone stale include actors anticipating each other's lines, emotional moments arriving on schedule rather than being provoked, and a general sense of performance rather than behaviour.

Directors keep scenes fresh in several ways. They stop rehearsing when a scene is understood rather than polished. They introduce small changes between takes, such as a new fact, a different action verb or a change to a prop, that give actors something new to respond to. They keep the actors' attention on each other rather than on results. They sometimes shoot rehearsals, because the first attempt can contain something that never returns. Many directors and cinematographers now roll on rehearsals routinely when the scene and lighting allow it.

Emotional continuity across an out-of-order schedule

Because scenes are shot out of order, the director must help actors keep track of where each character is emotionally at every point in the story. An actor shooting the reconciliation scene on day 3 and the fight that precedes it on day 15 needs to know, on day 3, exactly how much damage the fight did. Without this, performances may not connect when the film is assembled.

Directors handle this with an emotional map of each character's arc, often a simple chart showing intensity or key states in story order, and with brief conversations before each scene: "This is the morning after the kitchen. You haven't slept. You've decided not to mention the albums again." The script supervisor's notes record what was actually played, which matters when a later scene must connect with an earlier one.

Performance across takes and set-ups

Each scene is usually shot from several set-ups, and each set-up may need several takes. Directors make decisions about the order of coverage partly to protect performance. A common approach is to shoot the master first, to establish geography and blocking, then move in to closer shots. Some directors reverse this for emotionally demanding scenes, shooting the close-ups first while the actors are freshest, if the lighting plan allows.

Directors also decide which actor's coverage to shoot first. Usually the camera turns around after completing one side, and the second actor plays the scene again off-camera for the first actor's close-ups and then on camera for their own. Actors who give full performances off-camera, rather than just reading lines, help their partners enormously; good directors encourage this and thank actors who do it.

Across takes, a director's notes should help the actor explore rather than repeat. A useful pattern is to get one solid take that works, then use subsequent takes to try variations: a different tactic, a different tempo, a change in how a key line lands. This gives the editor real choices and keeps the actors engaged. When the director has what is needed, it is time to move on, even if more takes might find something better; time is limited and actors' energy is finite.

Different actors, different approaches

Actors vary enormously in how they work. Some arrive having decided every choice; others discover the role on set. Some want long conversations; others prefer a few words. Some need encouragement after every take; others want to be left alone. Some work from emotion, some from technique, some from physical detail. A director's job is to learn what each actor needs, often by asking directly in prep, and to adapt.

Ensembles add complexity. In a scene with actors of very different experience or approaches, the director must give each what they need without letting the scene fragment. A useful principle is to direct the relationship rather than individuals: notes that change what one character is doing to the other give both actors something to respond to.

When performances are not working

Sometimes a performance is not working, and the director must decide why. The problem may be the actor's understanding of the scene, which a conversation about circumstances and objectives can fix. It may be the staging, which forces awkward movements. It may be the scene itself, which may not work on the page. It may be tiredness, nerves or a personal difficulty. Diagnosis comes before treatment: changing notes repeatedly without understanding the problem usually makes things worse.

Some situations need particular care. A nervous actor may need reassurance, simpler tasks and a quieter set. An actor who disagrees with the director's interpretation deserves a genuine conversation, ideally in private and before shooting; sometimes the actor is right, and sometimes a compromise can be filmed both ways. An experienced star may expect more control than the director wants to give; mutual respect and clear explanation usually work better than confrontation. If an actor behaves abusively toward others, the director, producers and first AD must act, because everyone on set has a right to a safe workplace.
