Book excerpt: Most books about film production assume that you have an idea and a script to shoot. Most screenwriting books are geared to how to write a script that you can sell to Hollywood (as though the authors of these books had the slightest clue) and do not take into consideration that you might be shooting the script yourself, possibly with your own money. This book is about how to write a script properly that you can rationally shoot, how to shoot it, how to finish it, how to sell it, and also how to get it shown.
