- Action lines in present tense, lean and visual; only what the camera can see or hear.
- Character names centered in caps above their dialogue; parentheticals only when the delivery isn't obvious.
- Introduce each character once in caps with a 3-5 word visual tag.
- Keep action paragraphs short (1-3 lines). No camera directions unless essential.
