In episode four of Scriptnotes, Craig and I discuss migraines, kidney stones and zombie apocalypse preparations before we segue to the main topic: how screenwriters work with directors, from the first meeting to on-set etiquette to giving notes in post.
Screenwriters and directors often come at a project from different directions. The writer is trying to explain the movie he's already written; the director is trying to explore the movie he's planning to make.
By understanding what a director wants and needs, you stand the best chance of getting your movie on screen in a way that satisfies both of you.
