I can't remember exactly why, but I was alone in the house on an average autumnal afternoon in Lansdale, PA, and I was half-asleep on the couch watching TV... probably Dr. Shock! I would have been around seven years old.
Suddenly a weird, long commercial came on for a movie called "Silent Night, Deadly Night." I thought I was about to be murdered, it was the longest, scariest stretch of time in my young life up to that point. I was too paralyzed by fear to get up and switch the channel (no remotes in 1974).
Looking at this trailer from the distance of an ironic 34 years later on youtube, I can't be sure if it's exactly what I saw (it was called Silent Night, Deadly Night and the narration was different, that I remember) but it sure was LONG, or so it seemed.
Here I was a confirmed monster freak, with all the Aurora glow in the dark monster models, and a die-hard fan of local TV creature features, but there were no VCRs, no way to "capture" a film you liked; everything was ephemeral, one-time only... and this was the only time I saw the commercial for SILENT NIGHT, DEADLY NIGHT. It sort of fell into the realm of dream... a nightmare!
But even now I have a hard time even looking at the cover to Black Christmas. Do they really have to show the chick with the plastic bag on her head? Just looking at it, my lungs feel panicky...(which is why I'm not showing it; you can link to it, though, here)
