A line producer is a type of film or television producer who is the head of the production office management personnel during daily operations of a feature film, advertisement film, television film, or TV program. A line producer usually works on one film or episode of a TV program at a time. They are responsible for human resources and handling any problems that come up during production. Line producers also manage scheduling and the budget of a motion picture, as well as day-to-day physical aspects of the film production. According to Producers Guild of America (PGA) guidelines, the line producer is the individual who reports directly to the individual(s) receiving "Produced by" credit on the theatrical motion picture and is the single individual who has the primary responsibility for the logistics of the production, from pre-production through completion of production; all department heads report to the line producer. The line producer functions like a chief operations officer in running the production company. During pre-production, responsibilities include supervising the assembly of the shooting company, recruitment of key personnel and services, and production organization for how to shoot the script and transform it into a movie. The line producer plans start dates for everyone and everything, and monitors the budget in the lead up to picture. Film production generally follows a rigorous schedule. The line producer facilitates location scouting, set building and decorating, offices and stages, wardrobe, props, stunts, physical and visual effects, camera, lighting, rigging, transportation, crew and union relations, travel, cast and crew accommodation, contracting of legal permissions and agreements, safety and risk management, prep and shooting schedule. In short, the line producer oversees the joint planning, negotiations, implementation and accounting for production. In the studio system, the line producer reports to the studio and typically liaises with key executives of production divisions inside the studio such as physical production, legal, labor relations, insurance, and finance.
