Working with the editor on the set means that it is possible to keep track, at every moment, of the exact temperature of the trajectory of the scene - and know precisely what is required to continue, or precede, the action already shot. Like building a giant jigsaw puzzle. This is a freeing procedure because one is divested of all the options that might otherwise hamper one's choices. Clarity is possible. And that means one can relax into each shot, knowing the clear boundaries of where it might end or begin. And with relaxation, comes play.
