The Sixteen Story Steps presented by screenwriter and international script consultant Keith Cunningham in his book "The Soul of Screenwriting – The Sixteen Story Steps" represent a breakthrough in the development of screenplay theory. This is a new, more detailed understanding of dramatic structure based on universal narrative functions and the insights of mythologist Joseph Campbell. Cunningham takes a new approach to screenwriting, directly involving the screenwriter and the creative process. This marks a departure from the traditional approach, which is linear, deductive, and more rationally oriented. Cunningham's new visual, inductive, and psychological approach engages both hemispheres of the brain equally. Strong and compelling screenplays for films that audiences remember come from authors.
