Conflict generates a story’s action. Nothing moves forward in a story except through conflict. There can be no change in the characters without unavoidable conflict. 1 Conflict has a tendency to be physical because it makes for great visual drama. However, physical action can only sustain a viewer’s attention for a short while. Thus, conflict is not exclusively comprised of fights. To keep a viewer’s interest, conflict needs inner turmoil to keep things interesting. This ranges from psychological problems to a clash of personalities (see Unity of Opposites).
