After the script is written ensure EVERYBODY on the production team has a copy and is aware of any changes made. This is to ensure everybody is on the same exact page in the same exact book.
Okay guys repeat after me: Props and script MUST coincide. It doesn’t make no sense you have a comedy script with blood and spiders as props. No.
No matter what anybody wants to think, without everybody having the correct version of the script you are bringing to screen your shoot will fall apart. Seriously, I’ve had similar experience. Take from my production experience and mishap. Keep everybody in the loop at all times.
