El Movimiento a Través de lo Sólido

Single continuous move, no cut, 24mm at f/2.8, from a tenement stairwell into the flat beyond. The camera pushes past a dusty banister and a bicycle wheel in the foreground, reaches a painted-shut door, and carries straight through it. The interior of the passage is designed, not skipped: roughly half a second inside the door's guts — strata of old paint seen in section, splintered pine, a dead wasp between the panels, dust turning in a keyhole's thin beam — before the far side opens onto a kitchen with a running tap. The move never slows or stutters at the threshold, and keeps the operator's slight forward gait throughout. Alfonso Cuarón's unbroken traversals of space. Lit by stairwell bulb, then keyhole light, then window daylight — three distinct colour temperatures inside one move. Anamorphic barrel distortion at the wide end.
