Back to one: Return to your first position and standby to start your action again.

Background: When you hear the AD call, “Background,” it’s time for you to perform. Never look directly into the camera. And remember exactly what you were doing in a scene, so you can repeat your actions each time.

Call time: This is the time when you are expected to be on set. Remember early is on time, on time is late and late can mean you’re fired.

It’s a wrap: Filming is finished for the day. Time to return costumes, get signed out and go home!

Pantomime: If the AD calls “Pantomime,”  perform your actions without making a sound. Pretend you are talking, laughing, clapping, cheering, etc.

Production assistant: A production assistant, or PA, is a crew member who helps with various tasks on set, including extras wrangling.

Quiet on the set: When you hear the AD’s call for “Quiet on the set,” don’t make any sound. If one person is talking, it may sound like a whisper. If a group is talking, it sounds like a roar.

Rolling: Film is moving through the camera. Do not move yet. Your cue is coming next.
