I found this site a while back, searching for images of a movie theater I had a lot of good memories of. Sadly, it has been partially demolished after sitting empty and dark the past several years. But I found a photo of it in all it's summer 1984 glory, and for all I know I could have been inside the day it was taken!
What I didn't realize until now was, you can also search by movie title, and there are a lot of pics of old movie theaters showing the OT. Perhaps you might find the places you first saw them there. :)
