Great site! Found it while looking for info on a movie that scared the crap out of me when I was a kid. (Just finished watching DARK NIGHT OF THE SCARECROW for the first time in 30 years and now want to watch this other one if I can find it.)
I saw it on television — can’t remember if broadcast or cable — between 1977 and the summer of 1983. The basic premise is that some object is passing close to the Earth and is making people do crazy things. There was a scene in which people go crazy and attack each other in a grocery store, and another in which a guy puts a shotgun in his mouth and pulls the trigger for no reason.
I’m positive it isn’t NIGHT OF THE COMET, but I just can’t remember what the hell it is called. Hoping somebody remembers this old one.
UPDATE: NAME THAT TRAUMA SOLVED! Special thanks to kinderpal David Fullam for naming it with STARSHIP INVASIONS.
