 Screenplays and teleplays use a set of standardizations, beginning with proper formatting.These rules are in part to serve the practical purpose of making scripts uniformly readable "blueprints" of movies, and also to serve as a way of distinguishing a professional from an amateur.Motion picture screenplays intended for submission to mainstream studios, whether in the US or elsewhere in the world, are expected to conform to a standard typographical style known widely as the "studio format" which stipulates how elements of the screenplay such as scene headings, action, transitions, dialogue, character names, shots and parenthetical matter should be presented on the page, as well as font size and line spacing.
