Re: Your Modus Operandi
My system is similar to T.P. except my treatments are not lengthy. Since I'm a visual person, I always diagram a synthesis too. I think someone posted a great example of one on here a few years back. It is great to use as a bird's eye view of your story and spot holes before you start.
Writing the screenplay easily takes 3-4 months as I work it around the job that pays the bills.
Never mistake motion for action. ~Ernest Hemingway
