Props, Assistant Director & Continuity Departments is a wonderful study of three of the most important people on the set. The Props Master is responsible for all items used by the performers - no small task. The 1st Assistant Director acts as the bridge between the director and the crew. He's essentially the director's right-hand person. Finally, the Script Supervisor is certainly a critical position since they are responsible for making certain that things on the set remain the same between takes. This insures that there are no visible gaffs between takes.
