While I can't comment too much on this movie in detail, I do remember it scared the hell out of me as a kid when I first saw it. The "headless" mannequin dummy and the eerie pounding is what I remember about it that was so scary. I also remember the ending, which I won't give away here of course. (Not that you'll ever get to see this movie.)
NO ONE, I mean NO ONE remembers this movie. The fact that I'm the only one with a comment here so far for this movie attests to this. This TV movie scared me as much as DON'T BE AFRAID OF THE DARK and TRILOGY OF TERROR. Almost everyone remembers those though. I even saw DON'T BE AFRAID OF THE DARK on video at my local Blockbuster, but NEVER this one ANYWHERE EVER.
I haven't seen it in at least twenty years. I'd like to see this again somehow and my searches turn up nothing. It's not even listed in Leonard Maltin's fat movie book. If anyone knows where this can be found on video. Please email me.
