I'm a filmmaker with several features and documentaries under my belt. I've written an extensive article I call "Getting to the "yes" - to help screenwriters, producers, directors and actors understand the system they are pitching to.
It's a 26 page article that helps you navigate the "no's" of Hollywood!
I love your answer. I have started a Ning site that helps people get unstuck and thrive. I am going to be interviewing experts of all kinds. A lot of the participants are writers who might be interested in screenwriting, etc. Here is the site if you want to check it out. . .
Who is your target market? Which documentaries did you do?
