Beat Sheet Guide: Three-Act Structure, Save the Cat Beats and the Interval Block
By Gireesh Shanbbhag, Actor | Filmmaker | Screen Writer | Editor · Published 2026-09-21
Quick answer: A beat sheet is a list of the key turning points ("beats") of your story in order, written before the screenplay. The most common model is three-act structure: Act One (setup, about the first 25%), Act Two (confrontation, about 50%, with a midpoint reversal) and Act Three (resolution, about the last 25%). Blake Snyder's "Save the Cat" breaks this into 15 named beats with approximate page targets. Indian films usually place the interval at or near the midpoint.
Key takeaways
Write the beat sheet after the logline and before the scene list.
Each beat should change the hero's situation — if nothing changes, it is not a beat.
Page targets are guides for pacing, not laws.
In Indian cinema, the interval block is a structural beat in its own right: it must leave the audience desperate to return.
What is three-act structure?
Act One — Setup (pages 1–25 of a 110-page script): introduce the world and hero, then the inciting incident disrupts it, and the hero commits to a goal.
Act Two — Confrontation (pages 25–85): rising obstacles, a midpoint that raises the stakes or flips the story, and a crisis where everything seems lost.
Act Three — Resolution (pages 85–110): the climax, where the hero confronts the central conflict, and the new normal.
What are the 15 Save the Cat beats?
Page numbers are approximate for a 110-page script.
Opening image (1) — a snapshot of the hero's world "before".
Theme stated (5) — someone hints at the lesson the hero must learn.
Set-up (1–10) — the hero's life, flaws and relationships.
Catalyst (12) — the inciting incident.
Debate (12–25) — the hero hesitates.
Break into Two (25) — the hero chooses to act.
B story (30) — a secondary story, often a relationship, that carries the theme.
Fun and games (30–55) — the "promise of the premise"; trailer moments.
Midpoint (55) — a false victory or false defeat; stakes rise.
Bad guys close in (55–75) — pressure from outside and inside.
All is lost (75) — the lowest point.
Dark night of the soul (75–85) — the hero processes the loss.
Break into Three (85) — a new idea or realisation.
Finale (85–110) — the hero applies the lesson and wins or loses meaningfully.
Final image (110) — the mirror of the opening image, showing change.
How do Indian films use structure around the interval?
Most Indian theatrical features have an interval, so the story is designed in two halves. The interval block — the sequence just before the break — is usually a major reversal, revelation or confrontation that sits close to the midpoint beat. Writers often plan it first: "What is the moment that makes the audience rush back after the samosa?" The second half then escalates toward the climax. Songs are placed as beats too — a romance song often covers "fun and games", while a sad song can carry the "dark night of the soul".
How do I write a beat sheet, step by step?
Write your logline. See step 1 in how to write a screenplay in Kannada.
Decide your ending first; structure works backwards from the climax.
Fill the four anchor beats: catalyst, break into two, midpoint, all is lost.
Fill the remaining beats, one or two sentences each.
Check that every beat changes the hero's situation and that the midpoint and finale connect.
Expand beats into a scene list, then into the screenplay.
Example: a beat sheet in five lines
Catalyst: Meera's grandfather collapses during a Yakshagana performance.
Break into Two: Meera agrees to stay in the village and learn the role.
Midpoint / interval: the troupe's patron withdraws — the festival is cancelled.
All is lost: Meera's first public performance ends in humiliation.
Finale: Meera performs at the reopened festival, in her own modern style.
Build your beat sheet on a beat board
Kathe Kaara includes a visual beat board with structure templates, so you can drag beats into order, colour-code acts, and keep the beat sheet next to the screenplay it becomes. Pair it with character bibles and location guides in the same project.
Frequently asked questions
Is a beat sheet the same as an outline?
No. A beat sheet lists only major turning points; an outline lists every scene.
Do I have to follow Save the Cat?
No. It is a tool, not a formula. Many great films break it. Use it to diagnose pacing problems.
Where should the midpoint fall?
Around the middle of the script — page 55 of 110. In Indian films it often coincides with the interval.
How long should a beat sheet be?
One to two pages: one or two sentences per beat.
