BUS STOP - NIGHT\nRain. An empty bus shelter under one flickering streetlight. MARA (early 20s, short curly hair, oversized yellow raincoat, headphones around her neck) runs in, out of breath, and checks her phone: 11:58.\nShe looks down the empty road. Taillights disappear around the corner. She missed it.\nCLOSE on her phone screen going dark. (Prof's note: don't show readable text on the phone in previz, it never renders right.)\nShe sits on the bench, pulls her hood up.\n\nDirector's notes:\n- Our cinematographer wants an anamorphic widescreen look, 2.39:1.\n- Total opening: 12 seconds. (The first draft was 20 seconds and dragged.)\n- Shot sizes: we want one wide, one medium, one close-up and one insert.\n- Previz is just for blocking, so no dialogue or music needed.\n- Someone suggested casting a famous actress's look for Mara.
