Okay, heres a random one.
I don't know what it's called, and my description will be somewhat comical.
I don't remember if this is a movie, or just an episode of Tales from the Crypt or Darkside.
I suspect it's a movie
In any case, there's a person, or entity whose killing folk it ends when something happens to them, either they get burnt or melted down except its a false finish cause it gets back up, but it's little now, it looked like a small creature, almost like the skeleton from Tales from the Crypt and it chases someone (i think a lady?) around a house, or at least down a corridor, and they end up capturing it in a wooden box
A very vague description, but I'll give out 10 kudos to anyone who can name me what fits that bill
