At the request of Brad, Steven Guttag, and a Facebook friend who peppered me with DM's while I was experiencing explosive diarrhea in a Captain D's bathroom (oh wait, that was also Steven), I am creating a dedicated thread for discussion on Bill Warren's fabulous new multiplex in Broken Arrow, Oklahoma.
This is one of two "Grand Infinity" auditoriums in the building. Notice the screen with the deep curve.
![-](http://www.film-tech.com/uploads/uploads0503/WarrenCurtain.JPG) The red stuff is all dark during the feature. There's no accent lighting in the room at all.
To give a bit better perspective, here's a shot from where I initially sat, I think the fifth row or so.
![-](http://www.film-tech.com/uploads/uploads0503/WarrenCurtain2.JPG) My neck hurts.
Projection is from a 4K laser unit mounted in the ledge of the balcony, so throw is from the middle of the auditorium.

Steve's key questions were "how even is the lighting" and "what about the geometrics of the image". The lighting was pretty even, even sitting that close. But the picture bend was terrible from that close. The green band trailer notice looked like a warped smiley face. But if you moved further back, it was less of a problem. And that image was sharp. Very nice. You want to sit back further anyway to get the full Dolby ATMOS effect.
So will my commute to see movies at a Warren be moving from Wichita to Tulsa? No. I prefer to sit closer and the 13th Avenue Warren's flat screens work for me. I'm also not really sold on Dolby ATMOS so far. But props for trying this. Go check it out if you can.
Anyway...discuss.

Then I think they failed. The idea of a Cinerama type screen IS to sit close to have that thing wrap around you such that you have to turn your head to see it all...just like in real life.
As I figured, they are missing a key element..which is a lens that will distort the image such that it looks "normal" on the deep curved screen. With film, we mostly had that with the ISCO type "C" lenses...horizontal lines were pretty straight to the masking. Vertical lines would pincushion (progressively as you moved towards the sides of the image) but since the width was much larger than the height, it was really only objectionable in the corners. The Magna-Com65 would also do a decent job of creating a good "Flat" image on a deep curve screen.
What should be done for DCinema, if this sort of design is to continue, is to design a purpose built lens that fits the image to the screen and only distort the image in the horizontal plane. Given that Warren is purpose building these theatres, the needed throw ratio(s) should be known. Furthermore, with an anamorphic lens one could have a fixed prime lens for both flat and scope.
I personally think the concept shown hear has more merit than the "Escape" type theatre as the effect could apply to all features. Yes there are those that don't like the deep-curve screen but my 30+ years, I have found that the vast majority of people will flock to a theatre with one. You just don't get that effect in the home. However, you have to do it well. The image has to look as good as possible or it is just a gimmick.
