Save the Cat!: The Last Book on Screenwriting You’ll Ever Need by Blake Snyder provides a guide to screenwriting from an industry perspective, focusing on what a writer needs to do to prep for the act of writing. These techniques include creating a logline (or one-line), watching and analyzing movies in your chosen genre, creating a beat sheet, and building a board to layout scenes as a form of outlining. Skipping over actually writing process, he then reveals some screenplay “rules” and somethings to look for during edits if the finished draft isn’t working.
