AD's call — camera and sound are running, take begins. Entire set goes silent and still immediately.
The command "Ça tourne!" — or "Rolling!" in English-speaking contexts — is the starting signal for a take. The Assistant Director or the production assistant calls it out as soon as the camera and sound teams have signaled that their equipment is running and stable. It's the audible cue that things are getting serious: all movement freezes, all private conversations cease, actors position themselves, and the director prepares.
On set, it works like a chain reaction. The camera operator reports to the 1st AC: "Camera's running." The sound mixer confirms: "Sound's rolling." The AD waits for both signals, glances at the director — and then: "Rolling!" The call must be loud and clear, as it needs to be heard across the entire set, all the way to the back corner where the grips are. Some sets also have a light — a red lamp flashes, visually supporting the command. This is important on noisy locations or when multiple people are working with intense focus.
What happens next is ritualistic. The director waits two or three seconds — the latency until the cameras are truly operating stably. Then, they give the cue to start the scene. For actors, this means: the performance begins now. For extras: complete freedom of movement, precise as choreographed. The set freezes in this tension. No one coughs. No one moves into the light. This isn't drama — it's craft.
A common mistake by inexperienced ADs: calling the command too early. The camera needs its second to boot up, the sound needs to peak its levels. Those who are too impatient lead to takes with micro-drops or frames that aren't yet running stably. On the other end: waiting too long, until the tension breaks and the crew starts to push and gossip. Rhythm counts. "Rolling!" is not just information — it's also ceremony. It separates preparation from action. And that boundary must be clear.
