A long discussion of the structure of fiction and movies with detailed analysis of Millenium I from David Bordwell. Many here like this sort of thing -- all that outlining and page counting....
Bordwell cool quotes, most of which you guys already know:
.....a movie may display three parts, or four, or more (if the film is very long) or even two (if it’s unusually short). When the film has four parts, it tends to split the long second act that the manuals recommend into two.
A four-parter usually goes like this. A Setup lays down the circumstances and establishes the primary characters’ goals. The Complicating Action is a sort of counter-setup, modifying the original goals or creating new ones. At about the midpoint, there emerges a Development section characterized by delays, subplots, and backstory. There follows the Climax, which resolves the action by decisively achieving or failing to achieve the protagonist’s goals. The film typically ends with a brief Epilogue that establishes a settled state, happy or unhappy. Each of these sections is demarcated by a turning point—a moment of crisis, usually involving an unforeseen twist or a major decision by the protagonist.
With reference to the Dragon novel:
So I’m proposing a 138-page setup, a 150-page Complicating Action, and a 154-page Development. If you consider my two climaxes a single stretch, you have a 149-page climax section..... That makes the big parts roughly equal, with a tailpiece of 16 pages. the three-act/ four-part template provides a solid architecture for the plot.
