1. The faintest of all white bubbles drifting upwards in the water. This is a detail you simply can’t see even on the DVD. Film only: there’s dark, really dark, and SUPER dark. Shades of black with the faintest of white specks.
2. The two figures fighting in the alley below. One with a knife? Henry watches them somewhat disinterestedly through the window and then walks away.
3. Too much going on soundtrackwise to even describe. One detail: the pitch/density/loudness of the radiator, constantly changing.
