I recommend this book to every writer. McKee teaches the
principles of story dynamics better than anyone I know. You'll
learn how to create dimension in your characters, think in terms of
sequences, and apply story principles that work.
If you're looking for a formatting book... this is NOT the one you
want. Every screenwriter should keep McKee book close at hand.
Trottier's Screenwriter's Bible is the definitive source
for screenplay formatting and writing techniques and cheats. It
will help keep your script in proper industry format and demonstrates
different ways to apply screenwriting styles that best suits your
story. This is a must have reference book.
Need I say more? Every screenwriter should have this
book. It includes sample contracts and loads of information about
how NOT to get screwed. Great book!
