Years ago, I distinctly remember seeing a western movie which featured a wagon train in the middle of nowhere. Some people were riding by the wagon train, which was stopped. Up ahead, a crowd of settlers were gathered around watching two pioneer women fight. I don't think the wagon train was central to the theme of the movie, rather, the people were just riding by. The camera only showed the women fighting from a distance, and the people riding by didn't really pay any attention to the fight. For the life of me I can't remember the name of that movie, who starred in it, or when it was made. It was complete surprise to me.
Another movie, Ice Pirates, had a scene where the major characters were entering a colony, and a wild catfight was in progress. Again, the camera was focused on the main characters, not the fighters. And again, the main characters didn't pay any attention to the fight, as I remember.
Oh....one other comes to mind. I remember a movie or TV show, whereby in front of a school, one woman's car accidentally hit the back of another woman's car. The women got out and started arguing. Then before you know it, they were fighting, with one woman on top of the other on the hood of one of the cars. Again, this was not part of the movie theme, so it didn't get a lot of attention.
These are all I remember right off the top of my head.
