Blocking refers to the planning and rehearsing of a scene by mapping out when and how each actor will stand and move once cameras are rolling. Blocking allows the crew to plan the direction from which each shot will be taken from and decide what content will be captured. The process also allows actors to memorize where they will stand, walk, and face as they deliver or receive lines.

Child actors are required to have a chaperone on set with them. The role of the chaperone is to ensure that the actors have enough to eat and drink and that they are adequately rested. They also ensure that actors are where they need to be in terms of makeup, hair, costuming, sets, or tutoring. The chaperones, who may be a family member, close friend, or a professional, also should monitor the amount of time that the actors in their charge spend on set. (Child actors should spend no more than three hours at a time on set.) The chaperone must also ensure that the minimum amount of tutoring for each day is achieved (three hours).
