I also remember watching this movie as a kid and it scared the hell out of me as well. It has never left my mind even though I have not seen the film in more than 20 years. I just placed a bid for the movie on VHS at ebay and I'm hoping to win the auction so I can show it to my niece and see if it has the same affect on her (she's 14). Probably won't since she laughs at "The Exorcist" and "Friday the 13th." Ah, times have changed.
