I have a flashback of a movie I saw when I was a little kid. I don’t know how much help this will be, but I remember the ending scene (or maybe a scene close to the ending).
The setting is a shopping mall with a fountain in it. One person is about to shoot the other but suddenly the other person pulls out a tiny revolver from his shoe and shoots the person.
For some reason, I remember it was a family film from maybe the early 90s.
Sorry, that’s all I have. Any help is appreciated!
