I saw this on the old Prism cable network in the Philadelphia/South Jersey area in the early to mid 1980’s. It was a low budget affair, possibly independent, possibly a student production. It was in color and in English.
It seemed to have been filmed in a couple of abandoned locations, including some creepy ruins of a building overgrown with vegetation. I have the impression they may have written around the areas they had available. There were, I believe, three stories, framed by a group of young people (probably college students) telling them. The image that sticks in my head all these years is of a guy hovering and dazed under a single bare, blue light bulb in a very small, grey, dingy room. The point to that story, if I recall, was how someone had previously been found like this and a guy decides to investigate and winds up sharing the same fate.
I don’t remember anything else, really, but my impression is that it was a competent amateur production. It certainly creeped out my 12 or 13 year old self! Prism used to show some interesting stuff (I first saw Werner Herzog’s remake of Nosferatu there when I was maybe 11 and I became a lifelong fan of Herzog from the experience.) Early cable was without a net!
Any help would be appreciated, but I have a feeling the film I’m looking for was way under the radar… Here’s hoping! Thanks!
