I would have seen it in the 80s or early 90s. I have a very clear memory of one scene: The hero is climbing out from underground (i think he was forced to work in a mine?) and he pauses to sleep on a ledge but when he wakes up there are all these leeches sucking on him (he fights them off and makes it to the surface, which i remember as being very surreal). Please help, nobody seems to know it!
