Photoreal live-action film establishing shot, 35mm film grain, London under a heavy grey overcast sky: Big Ben and the Houses of Parliament seen across the Thames from Westminster Bridge, crowds fleeing on the bridge, and enormous silent alien ships hanging over the city, EXACTLY the same kind of alien ship as in the reference images: long organic hulls of pale bone-white weathered metal and bone with ribbed cracked seams, like huge fossil skeletons, never saucers. Cold muted palette, epic scale, no text.
