I, too, name Snow White as being my first, even though I'd only have been three in 1952. Which doesn't make a lot of sense, does it? Did people take their three-year-old to a movie at a nice downtown theeder in Columbus in 1952? For a Disney movie? Maybe?
The next Snow White re-release I see on IMDb, if correct, is 1958, and that doesn't ring true, either, because my movie memories from the 1958-1960 period in Columbus are not nearly so vague.
It's just that I've always carried this image of being with my mother in a dark theater and getting scared at the appropriate places, and I can't shake it. But there's literally no way to prove this one. If that wasn't my first, then MAYBE Oklahoma! in 1955, which seems a little late. Oh well.
