When I was 10, my father took me to see a couple of movies back to back in the 2 screen cinema in my home town. The movies? The Road Warrior and Conan the Barbarian, both first run.
We also saw Raiders of the Lost Ark by walking in at the opening of Ark and sitting through the whole movie again, back when the phrase "This is where I came in" meant something at the movies. Jaws was the first movie we watched on VHS, after recording it off cable around the same time period.
I think I saw every Arnold flick in the 80's at the theater with my father, including The Terminator and Predator.
It was my Grandfather who sat with me through 25 of the 57 times I saw ANH in theaters back when it was just "Star Wars" though. The first time I wanted to see it, they made me go see "Herbie goes Bananas" instead. I ran across the street in a fit of petulance and slipped down in front of a car which ran completely over me. I escaped with only cuts and bruises. The next 24 times there was no questions asked. :)
