Here's a pretty cool picture gallery of abandoned theatres - 75 in all - from across the country (even our "favorite" town in #19). There are several I'd love to get into and scronge around in for a day or two.
The old movie theatre in our towen was converted into an office building. 2 offices occupy the front of 1st floor and upstairs there is another large office. The original seating area & stage houses a specialty hardware store, has a couple different levels based on the sloped floor and is accessed from the rear. In our case, you really can't tell it used to be a movie theatre. The false facade was put up and the front accesses were totally reworked.
Do you have an abandoned or reused theatre in your town/city? Whats the status? Can you post a picture? What say you?
