Reading guide
The excerpt explains the screenwriter’s “one-sentence rule.” Hollywood producers hear hundreds of script pitches every day, and a writer may have only a few dozen seconds in an elevator to explain who the protagonist is and what happens. If you cannot state the core of the story in one sentence, you have not truly thought it through. A one-sentence premise is like a book cover: it should make people want to open the book immediately. Robin underlines the lesson: explain exactly what you do in one sentence.
Key points
- If you cannot finish within thirty seconds, the listener loses patience.
- State the core in one sentence: who is the protagonist, and what happens?
- If you cannot explain it in one sentence, you have not thought it through.
- Robin: explain exactly what you do in a single sentence.
