Query: ********** TEN STARS! ABSOLUTELY BUY THIS BOOK FIRST!

This book is ABSOLUTELY the best on the subject. And I've read _all_ of them: Field, Froug, Hunter, Seger, Halperin, and many more. The analyses of clasic and newer films are exhaustive and the "Tools" section provides an indispensible guide for any writer. It sits right next to my computer. When I sell my first screen play, David Howard will be the first one I call to say "Thank you."
