Rehearsal
Film rehearsal is not theatre rehearsal, and misunderstanding that is where a lot of directors go wrong. You're not drilling a performance to lock it in — you're building shared understanding and trust, and finding what the scene is, without using it up before the camera rolls. Here's how to rehearse for film.
Film and theatre rehearse for opposite reasons, and confusing them causes real damage. In theatre you rehearse for weeks to lock a performance that will then be repeated live, night after night, without a director present. In film, the director is present at every take, the camera captures spontaneity, and a performance that's been drilled to death arrives on set stale and mechanical — the actor is reciting a museum piece instead of living it. So film rehearsal has a different goal: not to fix and polish, but to build understanding, build trust, and explore — while carefully saving the spark of discovery for the camera.
What rehearsal is really for
Given that goal, the most valuable things you do in rehearsal are rarely running lines to perfection. They're the deeper alignments that make the shoot day fast and alive:
- Shared understanding. Get everyone agreeing on what the scene is about, what each character wants — so on set you're refining, not discovering the basics under time pressure.
- Trust and rapport. Rehearsal is where actors learn how you communicate and that you're safe to be vulnerable with. That relationship pays off on every take.
- Relationships between actors. Especially for people who've just met but play intimates or family — time together builds the history the scene assumes.
- Finding problems early. A line that won't play, a beat that isn't working — far better to discover it in a rehearsal room than at hour eleven on set.
- Exploration, not fixing. Try the scene several ways, follow tangents, get it wrong on purpose. You're mapping the territory, not paving one road.
Notice what's not on that list: nailing the exact final performance. That's deliberate. If you rehearse a scene until it's "perfect," you've often spent the one thing you most needed to save.
Don't over-rehearse — and rehearse the right things
The gravest rehearsal sin in film is over-rehearsing the emotional peak. If you make an actor hit the big cry or the explosive argument again and again in a bare room, you can drain it — you'll have used up the real thing before it ever reached the lens, and on the day you get a competent imitation of the feeling you already spent. So directors often talk around the peak moments in rehearsal, exploring the character and relationship and objectives, but leaving the actual detonation for the take. Meanwhile, some things genuinely benefit from rehearsal or a run before rolling: complicated blocking, dialogue-heavy exchanges that need rhythm, physical business, and anything technical the actors must coordinate with. The art is knowing which is which — rehearse the mechanics and the understanding, protect the spontaneity and the emotional peaks. And be pragmatic about the reality of low budgets: often you get no formal rehearsal at all, just a few minutes on set. Even then the principle holds — use those minutes to align on what the scene is and to build a little trust, not to drill the feeling out of it.
When I do get rehearsal time, I spend most of it talking, not running the scene — about who these people are, what happened before the scene starts, what they want from each other. Then we'll walk it through a couple of times loosely, and I'll deliberately stop before the big moment: "we know where that goes, let's save it." Actors almost always thank me for that. They'd rather arrive on set with something still to discover than have squeezed the life out of it in a rehearsal room three weeks earlier.
