Unit production manager (UPM) is the Directors Guild of America–approved title for the top below-the-line staff position responsible for the administration of a feature film or TV production. Alternate titles for this role on non-DGA signatory productions are production manager or production supervisor. He or she works closely with the project’s line producer. It is not uncommon for the line producer to function as UPM as well. A senior producer may assign a UPM to work concurrently on more than one production, for film, theatre, or television.
