All I can think of is that there are multiple versions floating around out there, because the one I saw defiinitely didn't look like the Bluray. It looked like the 35mm print, which had no red tint in the bar scene at all.
Anyway, forget the Bluray, forget the IMAX; they don't matter—my point is that DrDre is on the right track with what he's doing for that scene, and I hope he continues with it.
