I heard it said once that video or film is a five part process... plan, plan, plan tape/film and edit. Most folks I met want to skip the first 3/5s and get to the 'fun stuff' of the actual movie-making. But it is in that planning process that great stuff is devised.
I get asked occasionally if there are any good resources to learn the planning or script-writing phase. Well there is one I have read that is not at all a text-book but does provide some good insight in the script writing stage. The book is not new, written in 1994, but is a good one.
The author. Syd Field, has a number of books out on script-writing and I found this particular title a few years ago. It was an easy and interesting read. In Four Screenplays, he analyzes four movies that made it to the big-screen: Thelma & Louise, Terminator 2, Silence of the Lambs and Dances with
Wolves.
In the book he interviews Callie Khouri, James Cameron, Ted Tally and
Michael Blake - the four screen writers responsible for these four screen plays. What's interesting about this book is that each of the four movies are based on four different screen-play 'beginnnings'... from original work to adaptation from short story and novel. From Syd Fields website "This analysis of four
groundbreaking contemporary classics, in-depth interviews and
comparative remarks will help any screenwriter reach the goal of great
writing, commercial success, and winning entertainment"
