If you mean the Marietta square, I saw my first James Bond movie at the square theatre (Diamonds are Forever) in what, 69’?
West of the railroad tracks about 10 miles is where I grew up, lost mountain.
Lost Mountain was out in the country back then. But which theater on the square. There was the big one at the corner (later an off brand church when I was through there a decade or so ago - it was the Strand back in the day) and a much smaller, crummier one toward the middle of the block closer to the Dunaway’s drug store. (Cobb Theater, maybe. Google indicates my brain is still working.) I don’t think I was ever in the Strand. I was in the small one once for a friend’s birthday.
