Alan,
the hand on the door and the man on the landing who's shadow Chris was interested in are about 3 quarters of door's width away from each other, perhaps.
...
All I'm seeing, Barry, is that the shadow hits his head as soon as both legs have straightened up on the landing. Completely different to what we see with 'Upper Lovelady'!
We must have crossed wires somewhere Alan because the guy I'm talking about never reaches the landing.
Behind the cop with hand on door in the closer scene, Chris saw shadow only on right side of head, I'm saying when he lowers his head he gets caught, just the very top of it on the left.
