Ever heard of this made for TV movie from the late 80's or early 90's?

All I can remember of it is the bad guy is a real old skinny man with long white hair wearing a duster or trench coat. He drives a carriage pulled by dead horses and has this worm type animal as a 'pet'. The 'pet' ends up helping the good guy tho, who's in a house with a shotgun trying to keep the bad guy out. I remember him hiding in the fireplace holding the shot gun.
