This is the third edition of this book that I've purchased since I first became interested in screenwriting. The instructional portion continues to impress me and it has been updated to reflect new "rules" since the last edition. The book is actually divided into five books - how to write a screenplay, a workbook of 7 steps to a stunning script, proper formatting technique, writing & revising, and a marketing plan for selling your script. I recommend this book for all levels of writers, particularly beginners. It's an easy, enjoyable read. The large print is easy on the eyes. This is a very inexpensive book in light of all the information contained in it. If I could give it more than five stars, I would.
