Pitch
1. a concise verbal (and sometimes visual) presentation of an idea for a film or TV series generally made by a screenwriter or director to a producer or studio executive in the hope of attracting development finance to pay for the writing of a screenplay.
“Pitch” is a contraction of the phrase “sales pitch”. A pitch is used throughout different stages of production, such as casting and distribution, as well as to urge film producers to further fund a project. Filmmakers who devise a pitch tend to manufacture a production package, which is handed out to each potential investor during the pitch. The package contains the basic information for the filmmaker’s project, such as a plot synopsis and budgeting values.
