Skin: Pore-level realism, visible fuzz, asymmetrical moles, capillary redness, pore shadows consistent with the set lighting. Acting: Hollywood level, micro-pauses before reactions, precise gaze direction, lively eyes with catchlights, visible breathing through chest movements. Characters never stay still: they react constantly. Physics: Gravity and inertia respected, each mass has a realistic weight, correct contact shadows. No floating objects. Composition: Rule of thirds + golden ratio. Every character is in motion from the first frame. Continuity: Characters, props, and sets remain identical from one shot to another. No identity drift. Technical: Fluid movement at 24 frames per second. 8K details. No shaking. Audio: Ambient sound effects only. No music. No subtitles. Character: OLD MAN (<<<5571b746-cf71-4d00-856a-e63dfbc65ea5>>>), late sixties, metal-rimmed glasses slightly crooked under a shiny red sports helmet also slightly displaced, black chin strap still attached, gray mustache, white t-shirt pulled up showing his belly, red gym shorts, black elbow and knee pads, striped high socks, and flame roller skates (<<<12af3151-dc95-4411-83d7-e8a4d1fa8c04>>>). Scene: At the bottom of the slope (<<<46231bd6-1653-4ded-b50e-69c0ff113a83>>>), at the level of the white stripes of the crosswalk, near the fire hydrant. The old man arrives at maximum speed, impossible to control. SHOT 1: Lateral tracking shot, 35mm lens, fast pan to keep him in the frame. A wheel catches a crack in the sidewalk. His whole body tips forward beyond the point of no return: his arms deploy like those of a surprised bird, one leg kicks back, his glasses leave the bridge of his nose. He lets out a muffled cry. His body language evokes a comedy of blunders, but with perfectly realistic weight and physics. SHOT 2: Wide angle at asphalt level.
