SCRIPT READERSRemember, the people who read a script are trained and are used to being given well crafted, literate scripts. If you plan on writing out every camera angle and describing every prop and actor's emotion, you're not going to get anyone interested in the project unless you have been so successful in the past that your Oscar blinds the reader. In fact you are more likely to bore them or insult them.
Script readers, whether studio readers, production company assistants, directors, producers, etc., read a lot of scripts. They pick up a script and say to themselves: "Is this worth two hours of my time to read?" A script that is on yellow paper is hard on the eyes. A script in tiny font is hard on the eyes. A script that presents a wall of description with no breaks is hard on the eyes. A reader is likely to put down such a script and pick up the next one of the pile if it looked more pleasant to read. Don't let this happen to your screenplay.
