Film budgeting refers to the process by which a line producer, unit production manager, or filmmaker prepares a budget for a film production. This document, which could be over 150 pages long, is used to secure financing for and lead to pre-production and production of the film. Multiple drafts of the budget may be required to whittle down costs. A budget is typically divided into four sections: above the line (creative talent), below the line (direct production costs), post-production (editing, visual effects, etc.), and other (insurance, completion bond, etc.) Film financing can be acquired from a private investor, sponsor, product placement, film studio, entertainment company, and/or out-of-pocket funds.
