FilmCraft: Screenwriting by Tim Grierson - This is another in the beautful FilmCraft line - very well laid out with outstanding content. This is not really a how to book - Instead, each chapter is centered around a single screenwrtier and how they look at the subject.
Screenwriting looks at the foundation on which every great film is built—the script. Whether an original concept or an adaptation, the screenplay is the key to the success of a movie—good dialogue, story pacing, and character development are the framework everything else hangs on. Featuring in-depth interviews with modern masters of film including Stephen Gaghan, Guillermo Arriaga, Caroline Thompson, Hossein Amini, and Jean-Claude Carrière, this book reveals the mysteries behind how the best scripts are written and reach the screen.
