People near my age (and older) may have an easier time of this since there won’t be a conflict with TV movies (movies first seen on TV). But what is your first memory from a movie you saw at a theater?
In my own case, I can’t be 100% sure, since I don’t remember seeing a complete feature until well after the snippets I got from being in the theater with my mother or an aunt or somebody. In any case, I would have been 4 or 5 or so.
I remember sequences from Red River with John Wayne, Montgomery Clift, John Ireland, etc.
There was some Red Skelton comedy involving beds being shifted from room to room in a hospital. I had nightmares over this one!
The Claudette Colbert and Clark Gable It Happened One Night but only the scene where she hikes her skirt up to hitch a ride.
There are also some scenes from some WWII movie that I saw from across the street. The stupid theater had the screen so you could see it from outside if the main doors (lobby and screening room) were open. It could have been anything from the mid-40’s with a bunch of guys running around getting shot at.
I have checked IMDB for dates to try to square my age at the time and the release date of the movie, but all I can rely on are some fragmentary memories that are a big jumble.
I can’t even remember what that first full length feature would have been. Most likely a western or a film noir, and most likely something before 1948.
