I often watch movies, and to be honest, many of them leave me with the regret of watching the film in the first place. The book does a nice job of explaining the background work of film-making, and the difficulties that many people never hear about. Some people think that a writer writes a script, the movie-makers like it, and the movie is made. The process is much more complicated than that, and makes me wonder how some of the films today ever had multiple executives say "Let's make this into a movie!" Good inspiration for any future writers.
