This document provides an overview of the basic elements of a screenplay, including scene headings, big print (present tense action lines), dialogue, and stage directions. It discusses showing rather than telling through characters' actions, conveying necessary details while avoiding overwriting, and guiding the visuals to help readers envision the world being created without dictating exact shots. Dream sequences and flashbacks should be used carefully and indicated properly. The document also provides examples and links to annotated scripts and screenwriting tools.
