Hired by the Location Manager to be on-set before, during, and after the filming process. General responsibilities can include arriving first at the location to allow the set dressers into the set for preparation; maintaining the cleanliness of the location areas during filming (on larger budget projects this can include securing and supervising a contract clean-up crew or assigning such duties to a set PA); limiting the impact of a working production crew on the location grounds; fielding complaints from neighbors; and ultimately, at the end of the filming, managing on-set time and crew with regard to the closure of the location within contractually-permitted time constraints. There are generally one to three assistants on a shoot at any given time.
