Here’s the “demand Atlas” section of the official website. Put in your zip code (and email) and see what happens - my guess it that it directs you to the corporate headquarters of local theaters.
So far, Pittsburgh is the 4th most demanded. I had no idea that Ayn Rand was so big in Providence, RI.

I'm really lucky, in that AMC theaters is going to be showing it at a theater less than a mile from my place. I really want to see it, both because I want to see it, and because I want to support the producers. The problem is that I've got really bad arthritis and the last time I went to a movie, I could barely get up out of the seat once it was over. It was a painful experience. Still, I may go anyway.
