Lighting

Salutations Mr. Deakins,
I was looking through Shotdeck the other day putting together some examples for motivated light from lamps, and came across this still from Prisoners.
Just curious, was the light on his face from a tungsten source bounced into unbleached muslin and controlled off the back wall?
I really like how the quality of the falloff on his face feels so appropriately matched to the lamp beside him, while still giving a bit more dimension to the nearside cheek than the actual practical would. (And of course the ping of an eye light)
Thanks so much
