Book excerpt: Hundreds of books claim they can teach you how to write the perfect script. Listen up: your script doesnt need to be perfect to sell! It does need to include nine standard story elements. Producer, writer and story analyst Donna Michelle Anderson, best known in the industry as DMA, has been hammering this point home for more than a decade at UCLA Extension Writers Program, film fests, production companies and more, and as the founder and screenwriting instructor of the Movie in a Box one-day filmmaking seminars.With this concise guide, DMA brings you the simplest steps to unifying a theme, character arc and spine, then streamlining those elements into a sellable script. She calls it The 1-3-5 System. Youre going to call it a miracle.
