The Descent?

OK. So the studio that brought us SAW and HOSTEL,
and is previewing SAW III (brilliant poster graphics!),
is descending upon us everywhere on August 4th.

Fuck, I'm such a lame-o for not knowing the original photograph.
I thought it was Man Ray, then Steiglitz or Steichen,
but I haven't researched it, and it's a tough one to research.
-5 on the credibility factor for being stumped on one I should know.
Who's screaming now?

Love the graphics on this one too.
