Well, to answer some questions:
I used to work for Kerasotes Showplace Theaters, which was recently bought out by AMC, so lemme give ya'll some insight.
We did, in fact, show live events. Some of them were random opera stuff, concerts by groups I can't remember, as well as certain showings. I guess if we reach our goal, Alizée's concerts could be screened live.. that would be the day..
We also do have 3D projectors. We recently got a new version, though I'm not sure what the differences are, other then that we use different 3D glasses now.
Hope that helps, if any!
