How about the wolf in 'An American Werewolf in London'. I don't mean the werewolf but the wolves at the beginning, the ones you don't see. There is just this guy, out on the Yorkshire moors. All alone. It is dark and misty. He is afraid. Then, from out of the cold, wet, mist comes a howl, a howl full of terror and frustration. Something is out there, something not human. He pulls his coat tighter around him, though no coat could keep this cold out. Then the sound comes again, louder, closer....... I want my mummy.
