Unit
- Three-act structure: The most widely used narrative framework splits a story into setup, confrontation, and resolution. Act One introduces characters, setting, and the inciting incident that propels the protagonist into the central conflict. This act typically occupies the first 25% of the screenplay.
- Act Two: Often called the rising action, this middle act presents escalating obstacles and complications. The protagonist pursues their goal but faces increasing opposition. Midway through, a midpoint event raises stakes and shifts the story direction. Act Two is the longest, taking up about 50% of the script.
- Act Three: The resolution act includes the climax and denouement. The protagonist confronts the central conflict in a final showdown. After the climax, brief scenes show the aftermath and new equilibrium. Act Three comprises the remaining 25% of the script.
- Inciting incident: An event that disrupts the protagonist ordinary world and forces them to take action. It occurs within the first 10-15 pages and must be compelling enough to hook the audience. Without a strong inciting incident, the story lacks forward momentum.
- Plot points: Major turning points that end one act and begin the next. Plot Point One at the end of Act One sends the story in a new direction. Plot Point Two at the end of Act Two leads into the climax. These points are essential for structural clarity.
- Character arc alignment: The external plot must mirror the protagonist internal change. A character who starts fearful should gradually become courageous as the story progresses. The three acts correspond to the character desire, need, and transformation.
- Pacing within the structure: Each act has a different rhythm. Act One establishes tone and sets up questions. Act Two builds tension through reversals and complications. Act Three accelerates to a climax then decelerates into resolution. Understanding pacing helps maintain audience engagement.
- Genre modifications: Some genres modify the three-act structure. Comedies often have faster act breaks. Thrillers may delay the inciting incident. Horror films sometimes front-load the midpoint. Genre expectations inform structural choices while the core framework remains adaptable.
Design Principle
Principle: Dramatic Question Pacing
Definition: The dramatic question is the central story question (e.g., Will the hero save the day?) that keeps the audience invested. Proper pacing ensures the question is raised early, developed with complications, and answered only at the climax.
Application: In a thriller script, introduce the dramatic question in the first scene (e.g., Can the detective catch the killer before the next murder?). In Act Two, raise stakes and introduce false answers. Delay the final answer until the climax in Act Three to maintain suspense.
