In 2013 I started teaching a course at UCLA Extension Writers Program on adapting true stories into feature screenplays. It’s a ten-week online class, available from anywhere in the world. I use the Save the Cat books to help writers identify the proper genre for their adaptation of something historical, and its “beat sheet” as a method of arriving at their own unique take on the “story’ within the true facts.
Check my page at the Writers’ Program site to see if I’m teaching it next quarter…
I took classes at this program myself in the early stages of my career, and am excited about being part of the faculty there. They bill themselves as “the largest open-enrollment creative writing and screenwriting program in the nation.” (Probably in the world, actually.)
I also recommend my "Ten Key Principles Successful Writers Understand", and my series of audio downloads. And if you'd like me to read something you're working on, check out my consulting page.
