Oh, I'm gonna get weird on you here, check it out:
As a very young boy back in the 70s, I remember being taken to a local theater by my brother, sister and their friends, and this theater was showing old movies or pre-movie reels, so my first cinema memory was what I now think was black-and-white Flash Gordon!
When the Jessica Lange and Jeff Bridges version of King Kong was still in big city theaters, another theater in my town screened... check it out... Godzilla Vs Mechanikong! And I was taken to see that one.
My very first proper movie in a large city experience, was to go to two separate theaters that day, the first was to see the star-studded war film A Bridge Too Far in the afternoon. Then the other, later one in the evening, was... drum roll, please... Star Wars. Which involved standing in line, waiting for three hours, or so.
