The approach Julian outlines is one that has been utilized by a few
other "underground" cinemas (a couple of which are here in Chicago). It
is one that fails miserably, on a number of levels:
1. As pointed out by Eric, it is next to impossible to get a perfectly
finished flatwall surface (at least at any reasonable cost).
2. There is no way to properly position the screen channel speakers for
correct reproduction (something that a couple of other cinema chains
have yet to figure out).
3. There will be no acoustic treatment behind the screen (standard
practice for a THX style system).
4. I don't see how a screen masking system (a necessity for a
multi-format venue) would be easily employed without having the "screen"
surface forward of the wall by at least 1 foot or more.
If you are serious about wanting to provide a venue for the proper
presentation of film and video, I would sincerely suggest consulting
with someone knowledgeable in cinema construction before embarking on a
project of this type. There are numerous issues that come into play when
doing theater design (HVAC systems, acoustics, sight lines), not to
mention all the equipment considerations. While there are some economies
that can be realized in certain areas, it takes someone with skill and
experience to determine where the tradeoffs can be made without
sacrificing presentation quality.
There are numerous resources that can be had thru SMPTE, THX and others
that will serve as guidelines.
