Blake Snyder (1957-2009) worked as a screenwriter and producer for twenty years. His book Save the Cat!: The Last Book on Screenwriting You'll Ever Need and its sequels have guided screenwriters, novelists, and other creative thinkers for years and continue to be bestsellers. His methodology is also used by many development executives, managers, and producers due to its precise, easy, and honest appraisal of what it takes to write and develop stories in any medium.
