How to Write a Movie in 21 Days: The Inner Movie Method
No book can find your ideas for you, but this one provides a great service in helping you discover and develop a story, and to come up with the completed script. King helps you learn to think cinematically, in the language of the movies, and to keep asking the essential questions as they work: What's the story? Who is the story about? Do you care about the characters? Does anyone? King also tries to help you survive not just the structural pitfalls that can derail a script, but also the mental or emotional whirlpools that can prevent any artist from finishing a project.
