A screenplay, also known as a script, is a written work by screenwriters for a film, television show, or video game. It is a blueprint for the final product and includes the dialogue, movements, actions, and expressions of the characters. Screenplays are written in a specific format to distinguish between characters, action lines, and dialogue, and to guide the budget and schedule for its production. Proper screenplay format includes scene headings, action lines, character names, and more. The elements of a screenplay come together on the page in a specific format, and understanding and implementing format is crucial. A screenplay is the most essential part of the filmmaking process, and it is the single most important document used and referred to by all cast and crew members. The four basic components of a screenplay are images, action, sound, and dialogue, while the five foundational elements of a screenplay are character, want and need, plot, structure, conflict, and resolution. The ultimate goal of most screenwriters is to sell their screenplay, and the value of a screenplay is typically 10 to 15 percent of the productions budget.
