Thanks, samcook, an honor to read your words. Well, this is only the railroad, to say. The other foot of the table is the five twists script structure by Syd Field. After I publish the 12 stages of the Heroe's Journey, I will write about Syd Field. It's a good remind for people who write for the screen, and for those who teach script writting. I couldn't find again this structures without the request and pressure of my students at The National Cinema School in Caracas. So, teaching is the best way to learn... Following you!
