This was the first 'how to write screenplays' book I've ever bought, and it has encouraged me to pursue writing screenplays further. I was however a little disappointed to discover the book was last published in 1984,19 years ago, and I'm sure screenwriting has changed a lot since then. Also, there's nothing on how to layout/format your script in Word, and how to use abbreviations and all the other scripting conventions correctly. He talks about using double spacing, but all the scripts I've read don't adhere to this, which is confusing. This book needs a re-write to bring it up to date. For example, he talks about writing on a series of 3x5 cards, cutting and pasting (not using a computer), and I think once mentions the use of a word processor, which of course weren't really around then. Some of the chapters are too theoretical and lack practicality, for example chapter 2 on Structure. He tries to define what it is almost from a philosophical angle rather than through practical concrete example. What does it mean to have a 'tight' script, when does a passage 'work', and when does it not, and what does he mean when he says a script is 'sharp'? These quantities need explaining through example. Putting these chapters aside, Field is inspirational and generally structured in his approach. I found his paradigm tool particularly useful, which essentially broke the making of a script down into manageable chunks. A good first read on the subject, but not really comprehensive in its coverage.
