Rewrites
I have worked things out for over seven years on a single script before moving to the writing process and if I were to rewrite it as many times as you guys seem to think is needed there's no way it would be even remotely the story that I set out to tell.
Firstly, if you take seven years reworking your story, then the thing that hits the piece of paper isn't the first draft. It's a story that's had seven years of writing, and you are right, good preparation does go to produce better first drafts.
However, trying to make the piece perfect first draft slows the creative process for me. I'd rather spend some time plotting on file cards and making notes, bang out a rough first draft and get to know my characters. Usually by the end of the first draft I know them much better than when I first started writing. This allows me to go back and adjust the earlier parts of the film when I was still feeling my way. I then step away from the script for at least six weeks, go back to it, read it fresh and take notes. Stuff that looked stunning when I first looked at it, often doesn't look so great when I've got some distance from the project. I'll then go back and rewrite based on those thoughts. At this point I generally try to halve the amount of dialogue I've written, as I have a tendancy to over write in first draft.
The script then goes to my producer, who will pick up on things that I've missed, things that seemed obvious to me, but haven't translated onto the page. Mainly, these are character and plot inconsistencies. This process of notes and rewrites will go on until we both believe that the script works.
We then scout locations. This will often involve rewrites, as we find new elements in the location that will help shape the story.
Then we cast, read-through and run rehearsals. At this point re-writes will be developed to accomodate the performances of the actors, building on the strenghts that they bring to the party.
Then on location, during principle photography, additional rewrites may crop up to deal with contingencies we hadn't foreseen (location problems for instance)
For me, the script development process is something that makes the final product better. I don't believe that it has to take life out of a script.
As an independent film maker the time I invest in developing my script is the best thing I can do. It is the thing that makes everything else work.
I have never, ever had a first draft, that was anywhere as good as a fully developed script.
I've made a good living as a writer all my life, I've got a wall full of international awards to prove it and the one thing that I know for certain, is that good writing takes multiple drafts and that good ideas take time to develop.
