Handheld shaky camera, 20 seconds, dark comedy tone.
Snow White in classic dress stands in the forest cottage, smiling sweetly as she hands poisoned red apples to the seven dwarfs one by one. The dwarfs eagerly bite into the apples. One by one they freeze, eyes roll back, and collapse hard onto the wooden floor in a messy pile — bodies twitching then going completely still.
Camera quickly pans and zooms in handheld style onto Snow White’s face. She breaks into uncontrollable, maniacal laughter, head thrown back, eyes wide with pure evil delight, laughing harder and harder while looking down at the fallen dwarfs.
Low key lighting, slight film grain, continuous handheld shake throughout. No dialogue, only the sound of her escalating laughter.
A woman looks into a mirror, but her reflection starts moving independently, smiles, then steps out of the mirror and swaps places with her. The trapped "real" one bangs on the glass from inside.
