Cut For The Cutting Room Floor.
Regardless, there will always be the idea of the - 'cutting room floor' - and where some of your scenes, lines of dialogue, images and darlings will inevitably wind up as the director and editor shape the picture, cut for time, cut for flow, cut for pacing.
You never keep everything you shoot.
So what does that mean about the draft you wrote?
The idea of the cutting room floor idea can be a useful tool for a writer at any stage of the writing, as a way to look at the work and lighten the load, cut the excess, stay on the straight line of the story.
The tighter, dynamic drafts are always the ones that read best. And you're forced to keep your poetry at a high level when you have less room.
What is the 'jewel' of the scene? The emotional moment required that makes the scene important? The plot discovery that makes it crucial? What do we learn about the characters or their fate, why is it neccessary? And if it's not neccesary, lose it. If part of it isn't neccesary, lose that.
If you don't do it now, you will hit that moment in a meeting with a director, unless you're directing yourself, when you gaze down upon a scene and realize - "we'll never shoot this."
That happened to me a lot in the last few weeks, as we're in pre-production on my script. But as the last thing I had in production was ten years ago the memory of this had faded. It was a great wake up call.
Good to get rid of the scenes you know you won't shoot, now. Why won't you shoot them? Becasue they don't advance the character arc, they don't advance plot. Period.
If you cut them now, you're improving the script, making it tighter, a better film, and a document that will speak more as a production draft to those who know production.
I read the script of Saving Private Ryan by Robert Rodat that sold. It's a fabulous script, very tight, no extra scenes, nothing wasted (different ending of course), a page turner it flew along amidst a huge cast of characters and endless locations; but felt like you were watching the movie.
Think of the cutting room floor and keep a step ahead.
