2.2 Three-act structure

The three-act structure is the backbone of screenwriting. It divides a story into setup, confrontation, and resolution, helping writers create engaging narratives with clear beginnings, middles, and ends.

This structure guides pacing, character development, and plot progression. By organizing key events and turning points within this framework, screenwriters can craft well-balanced stories that satisfy audience expectations while allowing for creative flexibility.

Applying the Three-Act Structure

Narrative Organization

• Create clear narrative arc guiding audience through story's progression
• Balance length and pacing of each act (25% Act I, 50% Act II, 25% Act III)
• Place key plot points and turning points at act transitions
• Develop subplots and secondary character arcs within three-act framework
• Ensure proper character development throughout narrative
• Employ foreshadowing, plant and payoff, and thematic resonance across acts
• Adapt structure to fit different genres while maintaining core principles

Pacing and Tension Management

• Use act breaks to control story rhythm and audience engagement
• Build tension gradually throughout Act II, leading to climax in Act III
• Incorporate moments of relief or comic relief to balance intense scenes
• Vary scene length and pacing to create dynamic storytelling
• Use dialogue and action to drive story forward within each act
• Create mini-arcs within each act to maintain audience interest
• Employ cliffhangers or strong act breaks to encourage continued viewing
