Sure,
So just point by point:
-GH2 with a basic hack (44Mbs)
-Voigtlander 0.95 (can't remember f-stops throughout the shoot, but no ND-filter)
-I used a steadicam Merlin for support.
I often attach my GH2 (in its Rewo-cage) to the steadicam, just for shooting hand-held, not necessarily
using it as a steadicam. The arm gives a nice counter-weight, and can even function as a sort of monopod
in certain circumstances. (btw. GH2 + Voigtlander + Rewo-cage + videomic pro is just about the max
my steadicam can counterbalance)
-in post I basically CC'ed in FCPX for a bare minimum. I pushed the shadows towards blue & blue/purpleish, while highlights got a slight shift towards yellow. Mids were pushed just a bit towards the greens. That's about it.
-most of the flares and such were the result of filming with the setting sun hitting just the corners of the lens.
That's about it. There's some optical flow used in the staircase scenes, oh and of course a simple matte to frame it in 2.39:1.
That's about all I can tell.
Hope it's helpful!
