Three-act structure: the skeleton of almost every film
Setup, confrontation and resolution. A simple structure that explains why so many films breathe at the same pace.

The three-act structure divides a story into beginning, middle and end, separated by turning points that change the protagonist's direction. Screenwriter Syd Field popularized the model in screenwriting manuals from the 1970s onward.
Act one: setup
We meet the world and the character. An event pulls them out of routine and pushes them into the story.
Act two: confrontation
The character pursues a goal and faces growing obstacles. It is the longest stretch and the hardest to write.
Act three: resolution
The conflict reaches its peak and resolves. The character ends up different from how they started.
Breaking the rule
Many remarkable films play with the structure, telling the story out of order or refusing a clear resolution. But even those tend to work because audiences know the model and notice when it is being challenged.
