I remember seeing something like this when I was young. I remember it slightly so it may have been a movie, I don't know. All I pretty much remember is an elderly woman trying to get a pill out of a pill bottle and she drops them on a conveyor belt, she then crawls on the belt after them and gets crushed in some kind of roller thing? I know it sounds really gruesome but it's always bugged me that I can't remember it.
THE MANGLER.
Awesome! That is the movie! I didn't think anyone would figure it out for me. The movie sounds pretty terrible but I'll give it a shot. Just for old times sake. I must have only seen that scene of the movie when I was little.
Yeah, it's really bad. Robert Englund is in it and he's really the only reason to watch it. But maybe see it just so you can say "I've seen it".
Glad I could help!
