Unit Production Manager
1. Unit production manager (UPM) is the Directors Guild of America-approved title for an on-set executive responsible for the administration of a production; especially a film production.
A UPM is usually hired by a film producer or television producer, and is responsible for managing the production and regulating the costs of delivering the expected film or television show on budget at the end of principal photography. Based on a shooting script, the UPM will create a working budget during (pre-production, prior to the start of principal photography), thereby charting a recommended budgetary course…the UPM is responsible for the more detailed planning and execution of the below-the-line costs (primarily for physical production).
