Photorealistic live-action cinema shot on vintage black-and-white 35mm film stock, epic monochrome, deep inky blacks and blown-out highlights, high-contrast chiaroscuro, heavy natural film grain, slight gate weave and halation around lightning, anamorphic lens, real practical effects, realistic fur, feathers and moss. Not animated, not illustrated, not hand-drawn, not 3D render, no color. The characters are in constant, fast motion in every shot. A small, stocky, furry black French bulldog @Image1 with bat ears and large feathered black wings chases a glowing white butterfly through an ancient forest, out over open fields and up into the sky during a raging thunderstorm. The storm never stops: swirling clouds, driving rain, wind-whipped leaves and feathers and lightning flashing every few seconds, in every shot. The camera constantly spirals, orbits and tumbles with them. 200mm anamorphic lens, with horizontal lens flares, and bokeh effect.

Fast multi-shot sequence with hard cuts:

Shot 1 (0–2s): Macro close-up in a dark, mossy forest. The glowing butterfly rests on the Frenchie's wet black nose as rain drips off its whiskers and lightning flickers through the trees.
Shot 2 (2–4s): The butterfly flutters off. The Frenchie's eyes lock onto it, and it crouches low, ears pinned back, as its wings twitch open.
Shot 3 (4–6s): Low-angle shot. It pounces off a mossy log, its wings snapping fully open as rain and leaves explode around it.
Shot 4 (6–8s): A fast tracking shot behind it as it runs along a fallen tree trunk and launches into flight, flapping hard.
Shot 5 (8–10s): The camera spirals around it as it weaves between giant trees, chasing the glowing butterfly, while lightning strobes through the branches.
Shot 6 (10–12s): Close-up of its face mid-flight. Its jowls flap in the wind, rain streaks past and its eyes are fixed on the butterfly.
Shot 7 (12–14s): It skims low over a rushing stream, its wingtips splashing the water as the camera tumbles alongside it.
Shot 8 (14–16s): It bursts out of the treeline into a vast field of tall grass whipping in the wind, as a huge lightning bolt splits the sky ahead.
Shot 9 (16–18s): A fast tracking shot behind it, low over the thrashing grass, as it angles upward after the butterfly toward a flash of light in the clouds.
Shot 10 (18–21s): The camera orbits it as it climbs steeply into the swirling storm clouds, wings pumping, with rain and feathers whirling around it.
Shot 11 (21–24s): Low-angle wide shot looking up. It soars high in the sky, silhouetted against the clouds as lightning explodes behind it, and the butterfly glows just ahead.
Shot 12 (24–27s): It swoops down and lands on top of an ancient curved stone wall covered in thick moss and ivy, high above a misty valley, and turns its head to lick and groom one wing.
Shot 13 (27–30s): Side-profile medium shot. It tucks its wings in and settles down on the mossy stone, gazing out over the stormy, misty horizon as the butterfly flutters past it and lightning flashes in the distance.

Mood: epic, magical, adventurous. Lightning on every leap. No text.
