I saw Milo and Otis just a few weeks before turning 3 back in 1989 in the theaters. A few weeks after my birthday I saw The Little Mermaid in the theaters too.
Was that the Disney Hercules or the Steve Reeves' Hercules?
I really don't remember the first movie I saw.
But the ones I do remember seeing are Old Yeller (still haven't recovered), Ben Hur, The Interns (anyone remember the shows Ben Casey and Doctor Kildare?) and The Flower Drum Song.
I was probably around 8 or so, 1975'ish. Barely remember any of the movie, just a mental snapshot of one thing. Mostly I remember lots of kids and the popcorn that came in a container similar to a cereal box, only smaller.
Mine was Oliver and Company. I think I was about three years old. My grandma used to take me to see all the Disney movies and when they were re-released they would play downtown at a theatre so I saw all those too.
I remember seeing Bedknobs and Broomsticks, but that may not have been the first. My parents took us to see a James Bond movie at the drive-in when I was really young and I was bored silly. That may have been before Bedknobs and Broomsticks.
The first one I remember seeing was My Girl. It was released in 1991, so that would have made me 4. I may have gone to see Little Mermaid too, but I don't remember going to see it.
