Quick Reference

Three-Act Structure

The foundational narrative framework dividing a screenplay into Setup (Act I), Confrontation (Act II), and Resolution (Act III). Act I introduces the world and protagonist, Act II escalates conflict through rising action, and Act III delivers the climax and denouement.

Inciting Incident

The event that disrupts the protagonist's ordinary world and sets the central conflict of the story into motion. It typically occurs within the first 10-15 pages of a feature screenplay and forces the protagonist to respond.

Character Arc

The internal transformation a character undergoes over the course of a story. A well-crafted arc shows the protagonist changing beliefs, overcoming flaws, or gaining new understanding as a result of the events they experience.

Subtext

The underlying meaning beneath the surface of dialogue and action. Effective screenwriting relies on subtext to convey what characters truly think and feel without stating it explicitly, creating dramatic tension and audience engagement.

Beat

The smallest unit of dramatic action in a screenplay. A beat represents a single exchange, shift in emotion, or moment of change within a scene. Beats collectively build the rhythm and pacing of a scene and the overall script.

Logline

A one- or two-sentence summary of a screenplay that captures the protagonist, the central conflict, and the stakes. A strong logline conveys the essence of the story and its unique hook in a concise, compelling way.

Show, Don't Tell

A core screenwriting principle that favors revealing character and story through visual action, behavior, and implication rather than through expository dialogue or narration. Since film is a visual medium, effective scripts dramatize rather than explain.

Midpoint

A major turning point occurring roughly halfway through a screenplay that raises the stakes, shifts the protagonist's approach, or reveals critical new information. It often marks a transition from the protagonist reacting to events to actively pursuing a goal.

Screenplay Format

The standardized formatting conventions for professional screenplays, including 12-point Courier font, specific margins for dialogue, action lines, character names, and scene headings (slug lines). Proper format ensures approximately one page equals one minute of screen time.

Climax

The moment of highest dramatic tension in a screenplay where the central conflict reaches its peak and the protagonist faces their ultimate challenge. The climax determines the outcome of the story's main question and typically occurs near the end of Act III.
