Michael Hauge shows how his 6 Act structure for novels applies to screenplays. An interesting read from the point of view of understanding what goes where in stories.
Plot structure simply determines the sequence of events that lead the hero toward this objective. And here’s the good news: whether you’re writing romantic comedies, suspense thrillers, historical dramas or big budget science fiction, all successful Hollywood movies follow the same basic structure.
In a properly structured movie, the story consists of six basic stages, which are defined by five key turning points in the plot. Not only are these turning points always the same; they always occupy the same positions in the story. So what happens at the 25% point of a 90-minute comedy will be identical to what happens at the same percentage of a three-hour epic. (These percentages apply both to the running time of the film and the pages of your screenplay.)
