Another movie I can't remember is like one of those tales from the darkside movies, but all I remember is the man telling his son about a monster with long arms, he can here you from miles away and when it can't to the end of the movie the monster came and his arms was so long I think... it went around the house and smash the family that was telling the scary stories.

And the knuckles were as big as basketballs. That's all I remember. What is it??

It's an episode of Tales from the Darkside called Seasons of Belief.
