When talking about a film set, you often hear the term "P.A.". This stands for production assistant. This person is the assistant to the first assistant director. These guys are the lowest in the totem pole. PA's can be asked to do any general task. This could involve being hands on working on set, or doing menial work like getting coffee. If you are looking to work on set or in production, becoming a PA is one of the easiest jobs you can find and it is also one of the easiest ways to get your foot in the door. Most accomplished film directors started out as a PA on a film set.
