Why not the standard 1.85? Are the curtains set for the 1.78 ratio (no IMAX) or does it have black bars (some screen showing) on the sides?
They recently converted my local theater to one of the new digiIMAX setups.
When Avatar started it became slightly side-boxed (maybe 12-18" lost on each side), I'm actually a little puzzled about why they didn't just extend the screen a touch higher and lower, then it would've fit at 1:78 to the full width.
More oddly at a real IMAX theater, using 3D film projection, I noticed that it was not just letterboxed (of course for a 1.4:1 ratio screen) but also side boxed. Maybe loosing 4-6' on each side. My only guess is that some, many, all real IMAX theaters just use the same bulb they use to project their 2D stuff and when they go to 3D and with the loss of light due to polarization they can't fill the full screen width??? I'm not sure but it almost seemed like the one here looked even taller than 1:78, if not by a lot.
