Sorry to have to add another “name the movie” post, but this is driving me crazy. I must have seen this something like 30 years ago on the lateshow, and haven’t a clue where it’s from.
It’s a black and white movie; some people (the main character I think, and a friend) are in the local pharmacy chatting with the elderly druggist. Cut to outside (it’s night), where in the shadows a shaking, sweat drenched addict is staring at the pharmacy entrance. He pulls a revolver out of his pocket, stands there with it a few moments as if making up his mind, then goes into the drug store. He goes up to the counter window the druggist is behind and demands narcotics. That’s all I can remember.
