Script makeup is a term used in the film and television industry to refer to the process of creating the written dialogue for a production. The two main components of script makeup are scenes, which are the individual segments of a production, and LINES, which are the spoken words of the characters. Scenes are typically composed of multiple LINES and can be thought of as the building blocks of a script. LINES are the actual words that the actors speak and are the most important part of script makeup.
